TEACHING EARTH SCIENCES ● Volume 26 ● Number 3, 2001<br />

Editorial<br />

The Key Stage 3 National Strategy has now hit UK<br />

secondary schools, with new and highly-structured<br />

approaches to <strong>teaching</strong> and learning advocated<br />

(and required?) for all schools. First to be<br />

implemented are literacy and numeracy, not only within<br />

English/maths lessons but also across the whole<br />

school curriculum. Literacy is the most advanced in its<br />

introduction in schools, apparently because its documentation<br />

has been produced slightly earlier than the<br />

maths materials! For Key Stage 3 teachers, other than<br />

English specialists, the key document is a large leverarch<br />

file called Literacy Across the Curriculum (DFEE<br />

2001) which was published in April 2001 for implementation<br />

during the current academic year. This<br />

INSET file is full of suggestions for enhancing children’s<br />

literacy across the KS3 curriculum. There is<br />

much that is not new but nevertheless the document<br />

provides a comprehensive source of material.<br />

Although the KS3 Literacy Strategy is obviously<br />

intended for children in Years 7, 8 and 9 (aged 11-14<br />

years), there is much that can be adapted for use in Key<br />

Stage 4 and post-16. For example the section on<br />

“Spelling and Vocabulary” includes, among other<br />

things, a checklist of 25 different strategies for improving<br />

students’ grasp of specialist words. Most of these are<br />

appropriate for post-16 <strong>teaching</strong>: hands up all post-16<br />

teachers whose students always spell “environment”<br />

correctly, with the middle “n” intact!<br />

The section called “Writing Non-fiction” is likely to<br />

be one of the most relevant sections for TES readers.<br />

Many of the issues addressed in this section relate not<br />

only to writing but also to reading, although later sections<br />

in the file deal with reading more explicitly.<br />

Analysing texts is one of these issues. Students are<br />

encouraged to examine texts (either written or read by<br />

them) at three levels: text; sentence; and word. Different<br />

questions need to be asked at each level and,<br />

through evaluation and re-drafting, written texts can be<br />

improved. By employing the same analyses students<br />

can enhance their understanding of their reading texts.<br />

This leads me conveniently to the use of narrative in<br />

<strong>teaching</strong> geoscience: an issue which is, unsurprisingly,<br />

not thoroughly covered in the KS3 strategy.<br />

Many readers will know of the so-called Deprat<br />

Affair. Roger Osborne (1999) provides a crisp account.<br />

The book is written rather as a thriller, with deliberate<br />

withholding of the final outcome till late in the book. It<br />

is a good read and not a lengthy book. I won’t spoil it for<br />

you now: well, not much anyway.<br />

Briefly, and for the uninitiated, during the first<br />

decade of the Twentieth Century Jaques Deprat (born<br />

1880) rose to become one of the most highly-regarded<br />

young geologists in France, with an international<br />

reputation. In fact his rise within the profession was<br />

meteoric. After obtaining a doctorate at the Sorbonne,<br />

he set off with his wife and two children in 1909 to<br />

French Indo-China as Head of the Geological Service<br />

of Indo-China. French Indo-China comprised present-day<br />

Vietnam, Cambodia and Laos. Deprat was<br />

based in Hanoi.<br />

Deprat was an active climber and explorer and much<br />

of his work in Indo-China involved fieldwork in<br />

remote and inhospitable localities. The narrator paints<br />

a vivid picture of a glamorous life . Deprat published his<br />

work regularly, although this was often a long-drawnout<br />

process because of the ship travel time to France.<br />

Specimens and documents were constantly and routinely<br />

moving between colony and mother country.<br />

Deprat’s international standing continued to strengthen,<br />

largely as a result of his pioneer work in structural<br />

geology: the reputation of the French Indo-China Geological<br />

Service rose accordingly. Then in 1917 the first<br />

bombshell struck: he was accused of fraud. To be precise,<br />

he was accused of placing some European trilobite<br />

specimens alongside some obtained in Indo-China.<br />

Trinucleus and Dalmanites spp. were involved. Clearly<br />

this was a most serious accusation and the story really<br />

starts here: I won’t go on.<br />

The Deprat story has all the key ingredients of a<br />

successful whodunnit: several suspects, strong personalities,<br />

envy, conspiracy, ambition, nepotism and so<br />

forth. For TES readers it has the extra ingredient of<br />

geology. Added to these are the twists in the tale itself:<br />

it is definitely not a straightforward story and the<br />

extent to which we have achieved “closure” remains<br />

highly debatable.<br />

How can we use rich narrative material such as this<br />

(Osborne 1999) in our geoscience <strong>teaching</strong>? First, we<br />

should recognise that many students, post-16 or otherwise,<br />

take well to such stories so we might ensure they<br />

engage with them. The reading simply enriches the<br />

experiences of some, but obviously not of all.<br />

Second, and more systematically, we might be able to<br />

use the narrative as stimulus material: a “way in” to the<br />

study of trilobites, investigations, structural geology,<br />

plate movements or whatever. This is particularly<br />

important for those learners who relate more readily to<br />

tales of human interaction than they do to scientific<br />

accounts (which they often perceive as cold)<br />

Third, as all teachers are teachers of literacy, we<br />

might be able to use sections of the text, or material<br />

written by ourselves covering the same ground, as the<br />

basis for analysis at text, sentence or word levels. At the<br />

word level, for example, the Deprat story involves not<br />

only the two trilobite genera named above but also several<br />

other fossil species, nappes, Tethys, various lithologies,<br />

Palaeozoic geographies, fieldwork procedures and<br />

conventions and so forth. At the sentence level the fol-<br />

lowing sample from Osborne (1999) is offered as a<br />

potentially fruitful case for analysis in terms of language<br />

and geology: “There are numerous specimens of Ptychaspis<br />

walcotti, a fossil trilobite from the Cambrian, and<br />

Deprat had found an example of Trinucleus ornatus<br />

known from Ordovician strata in Europe – one of the<br />

suspect trilobites” (p. 197). At the text level the entire<br />

book provides a tightly-structured narrative, with some<br />

key facts withheld till the closing chapters .....but tantalisingly<br />

suggested in the earlier chapters.<br />

Lastly, I am wondering if there is scope to work up a<br />

learning activity based on the Deprat material which<br />

develops children’s literacy and geoscience skills? It<br />

could require students to analyse the geological evidence<br />

and propose solutions: any offers?<br />

From the ESTA Chair:<br />

What a Year! 2000-2001<br />

How many times have we heard that phrase over the last twelve months – and<br />

with justification? Taking the period between the two AGMs – the froth of<br />

the Millennium celebrations was beginning to blow away – the Dome was<br />

deflated – getting anywhere by road, then rail (and now air) was a nightmare – an<br />

ever-warming or at least more variable climate, and that was before the ESTA conference<br />

at Kingston. Within 48 hours, the whole World was plunged into turmoil.<br />

By contrast, a review of developments across <strong>Earth</strong> science as a whole, let<br />

alone the UK or <strong>Earth</strong> science <strong>teaching</strong> and ESTA in particular, appears so<br />

infinitesimal as to be unworthy of consideration. But there are many positives<br />

to report here in the face of such wide-ranging despondency.<br />

At the beginning of our year, the first tentative moves had been made to<br />

engage the co-operation of the Royal Society of Chemistry (RSC) and these<br />

had received an enthusiastic response. The aim was to seek the involvement<br />

of those <strong>teaching</strong> ‘mainstream’ sciences to improve the quality of delivery<br />

of <strong>Earth</strong> science in all schools – starting with the secondary sector. Hosted<br />

by the Royal Society, the first full meeting went exceptionally well, and<br />

engaged the RSC, the Institute of Physics and the Institute of Biology,<br />

together with representatives of the geological community. A surprise<br />

bonus was the announcement by Annette Thomas that UK Offshore<br />

Operators <strong>Association</strong> (UKOOA) was prepared to underwrite the running<br />

costs of the Joint <strong>Earth</strong> <strong>Science</strong> Education Initiative (JESEI) and this no<br />

doubt stimulated the three scientific Institutions to add their support in<br />

their respective fields. Our sincere thanks go to all concerned.<br />

So the mythology of all-pervasive antagonism to the <strong>Earth</strong> sciences by<br />

non-<strong>Earth</strong> scientist teachers was not only debunked: there was a real spirit<br />

of engagement by people prepared to back words with action and finance.<br />

This is of course the ‘official view from the top’. The position at the chalk-<br />

(or should we say calcined gypsum) face may not yet be so enlightened, but<br />

the mechanism of cascading authoritative and proven quality <strong>Earth</strong> science<br />

<strong>teaching</strong> materials with the endorsement of their own institutions is<br />

designed to address this situation precisely. That was the essential groundwork.<br />

By the end of the summer, the hard grind of producing that quality<br />

material, the decisions on the most appropriate vehicle for dissemination,<br />

style of presentation etc were only just beginning.<br />

If you feel that you could help this initiative in any way, or have useful<br />

ideas, please contact me (especially if you are at heart a converted chemist,<br />

physicist or biologist!). Later stages will need to address primary level and<br />

links with geography – and, perhaps in the far distance, informing the wider<br />

public of good <strong>Earth</strong> science.<br />

Another ‘reason to be cheerful’, over the year has been the marked success<br />

of the <strong>Earth</strong> <strong>Science</strong> Education Unit at the University of Keele. Whereas this<br />

is not strictly an ESTA activity, access to the Keele infrastructure has enabled<br />

ESTA members to pilot an invaluable INSET service (which logistically<br />

ESTA itself would have been unable to deliver at this scale). Moreover it has<br />

now achieved a standard sufficiently high in terms of quality and results to<br />

attract further substantial funding from UKOOA to cover the costs of a<br />

national ‘roll out’. Long may this partnership continue.<br />

Having served on the Primary Group for eleven years (and providing<br />

INSET as far back as the Liverpool conference in 1991) I know that the consistent<br />

hard work of members has been very largely unsung. They are now<br />

building on the excellent pack on Rocks, by drawing up <strong>teaching</strong> material on<br />

soils. Within their relatively slender budget, their output is very good value for<br />

money indeed. Neither of these would have been possible without the generous<br />

support of the Curry Fund – we are most grateful. Cont. on page 88<br />

We should take this opportunity to thank Geo Supplies<br />

for all their efforts on our behalf over the last 15<br />

years. The new look journal also represents a great deal<br />

of hard work, particularly on the part of Roger Trend.<br />

This should mark the first step in improving ESTA’s<br />

presentation. The academic content of ESTA’s output<br />

has always been good; the ideas have been first rate (see<br />

above!) – this is endorsed by the extent to which they<br />

are copied by others! We now need to extend this standard<br />

to all our work – we live in a highly competitive,<br />

design-conscious world. Having worked in the print<br />

industry, I am only too aware that poor design can be<br />

the downfall of so many otherwise first class initiatives.<br />

The relaunch of the ESTA web site marks another<br />

advance in the same direction – thanks to Helen King<br />

for all her early work and to Carol Levitt in setting up<br />

the new site.<br />

Tribute also goes to Geraint Owen and Duncan<br />

Hawley for rescuing the Swansea Conference last year<br />

and to Neil Thomas’ valiant effort in turning around<br />

the Kingston Conference. Peter Kennett has been heavily<br />

involved in planning the 2002 conference at the<br />

British Geological Survey near Nottingham – this<br />

already promises to be a conference with a difference<br />

and one not to be missed.<br />

The year also saw a number of Council changes with<br />

Alastair Fleming, Andy Britnell, Polly Rhodes and Jane<br />

Butterfield moving on and Owain Thomas (my father’s<br />

namesake, but I assure you, no relation – nor are any of the<br />

other Thomas’s featuring here!) will be joining Council.<br />

We hope to announce other appointments shortly. In particular<br />

the work of Alastair Fleming over many, many<br />

years for ESTA deserves special mention. Although he is<br />

stepping down from Council for a well deserved retirement,<br />

he continues to play an active part in JESEI.<br />

No list can be comprehensive in recording adequately<br />

all the work of those in ESTA over the year and<br />

particularly that of my fellow Council members –<br />

thanks to you all.<br />

Where next? We need to continue developing and<br />

extending partnerships as exemplified by JESEI and<br />

ESEU; we need to extend and cascade some of these<br />

activities into the geography and primary fields; to continue<br />

upgrading our presentational standards; and in<br />

the longer term to consider other initiatives such as<br />

informal public education. We need to do this in the<br />

context of a well thought out (say 5 year) plan. (see page<br />

116 for Further Thoughts).<br />

Editor’s Note. Readers will have noticed the new-look TES. ESTA Council hopes that it meets with members’<br />

approval: please let me have your response. ESTA has also changed its design and production<br />

company. Character Design, based in rural Herefordshire, comprises Richard and Kerry Low: I have<br />

invited them to tell us about themselves.......<br />

We met working for a small graphic design company in Sussex at the foot of the South Downs and probably<br />

spent too many lunch hours walking up on the Downs and imagining living in the countryside.<br />

In the summer of 1997 we moved to Haywards Heath, to set up “Character Design”. We decided to work<br />

from home to keep costs down and avoid commuting: this then developed into a whole new way of working.<br />

Most of our work is now carried out using email, sending proofs digitally to the printers. Although this cuts<br />

down on meetings with our clients, our top priority at all times is to give a full personal service.<br />

We work with a number of associations, companies and individual business owners based in Brighton, London,<br />

Cambridge, Macclesfield and now Exeter (TES Editor). Our work varies: the majority is regular publications,<br />

newsletters and magazines which often means working into the night to achieve deadlines. We are also<br />

involved in the production and maintenance of websites.<br />

In November 1999 we moved into ‘Highridge’ in Herefordshire, with all our clients staying in tow. We now<br />

have a wonderful scenic view from our office and are able to walk straight out of our house into the fields or<br />

get lost in our garden - well worth the hard work!<br />

Working long hours during the week we spend every possible minute of the weekend outside, walking and<br />

cycling with our two children Sean and Emily.<br />

<strong>Earth</strong> System <strong>Science</strong>:<br />

A Better Way to Teach <strong>Science</strong> Enquiry<br />

RICHARD A. DUSCHL<br />

This paper was delivered as the Keynote Lecture at the Annual Conference of the <strong>Earth</strong> <strong>Science</strong><br />

Teachers <strong>Association</strong> at Kingston University in September 2001. It provides an overview of the<br />

context in which <strong>Earth</strong> System <strong>Science</strong> has emerged as the dominant perspective on global<br />

issues. This then provides the platform for the consideration of the <strong>Earth</strong> System curriculum<br />

frameworks which have been developed over the last decade. The lecture and this article are<br />

based on the chapter by Duschl and Smith in “Subject-Specific Instructional Methods and<br />

Activities”, Advances in Research on Teaching, Volume 8 (Duschl & Smith 2001).<br />

Introduction<br />

The second half of the 20th Century has been a time of<br />

rapid change in the character of the <strong>Earth</strong> sciences. The<br />

transition is one moving away from a focus on the surface<br />

geology of mapping and mining and toward a focus<br />

on global change and <strong>Earth</strong> systems (Mayer & Armstrong,<br />

1990). A science once dominated by historical<br />

types of explanations revealing the ‘story in the rocks’ is<br />

slowly evolving into a causal modelling science for<br />

making predictions (e.g., climate changes, <strong>Earth</strong>quakes,<br />

volcanic eruptions, flooding, hurricanes) and understanding<br />

how human activity effects global change.<br />

Thus, not surprisingly, the information or subject matter<br />

and the cognitive and the material tools needed to<br />

engage in <strong>Earth</strong> science inquiry have shifted as well.<br />

John McPhee elegantly captures the character of this<br />

change in his book Rising From the Plain. The story is<br />

about the geology of Wyoming told through the experiences<br />

of a high country, Rocky Mountain regional field<br />

geologist – Dave Love. For Love, geology was a kind of<br />

story telling. Through experiences of touching different<br />

geologic structures, you piece together the implied tectonics;<br />

i.e., the story in the rocks. He, like many other<br />

geologists, relate to the Hindu fable of blind men and<br />

the elephant (each individual feeling a different part of<br />

the elephant comes to different opinions of what it is).<br />

But field geologists like Dave Love are a dieing breed.<br />

In recent years, the number of ways to feel the elephant<br />

has importantly increased. While science has<br />

assimilated such instruments as the scanning transmission<br />

electron microscope, the inductively coupled plasma<br />

spectrophotometer, and the 39 Ar/ 40 Ar laser microbe<br />

. . . .the percentage of geologists has steadily diminished<br />

who go out in the summer and deal with rock, and the<br />

number of people has commensurately risen who work<br />

the year around in fluorescent light with their noses on<br />

printouts. (McPhee 1986, p 146).<br />

Feeding facts and fragments of the <strong>Earth</strong> into laboratory<br />

machines is referred to as “black-box geology” carried<br />

out by “analog geologists” (McPhee 1986, p 146).<br />

At the beginning of the 1900s and well into the 20th<br />

Century geology and the other <strong>Earth</strong> sciences were<br />

essentially atheoretical disciplines. The theories and<br />

paradigms that influenced geological inquiry came<br />

from the physical sciences – i.e., physics and chemistry.<br />

In the words of Thomas Kuhn (1970), geology and the<br />

other <strong>Earth</strong> sciences (e.g., oceanography, climatology,<br />

planetary geology, meteorology) were immature sciences<br />

since they lacked an organizing paradigm.<br />

The rapid changes in technology during the 20th<br />

Century have significantly impacted all the sciences.<br />

But the impacts on the <strong>Earth</strong> and geological sciences<br />

were nothing short of revolutionary. For during this<br />

past century the geological sciences made the transition<br />

from an immature science to a mature paradigm-driven<br />

science. Furthermore, observational techniques, tools<br />

and guiding conceptions (e.g., theoretical frameworks)<br />

have evolved and along the way shifted what comes to<br />

count as doing <strong>Earth</strong> science research and inquiry. In<br />

brief, descriptive inquiry approaches to the <strong>Earth</strong> sciences<br />

have given way to model-based inquiry<br />

approaches. The focus on local mapping and mining,<br />

and human-observational techniques have yielded to<br />

global mapping and modelling, and instrument-observational<br />

techniques. New tools like websites and CD-<br />

Roms have literally made it possible for students of the<br />

<strong>Earth</strong> sciences to have direct access to the raw data and<br />

models being used to study planet <strong>Earth</strong>.<br />

Consider the release of classified satellite imagery<br />

data. For approximately 30 years, Landsat satellites<br />

snapped pictures of the surface of the <strong>Earth</strong>. Employing<br />

5 bands of electromagnetic radiation (3 visible light<br />

bands and 2 infrared light bands), details about the surface<br />

of the <strong>Earth</strong> are revealed. The amount of information<br />

is enormous and computer technologies have now<br />

made this data available for public use. Schools with<br />

online capabilities can access the data. Such databases<br />

allow local, regional, and global groups to conduct<br />

inquiries about environmental and climatic changes.<br />

Consider the Terra mission that monitors the vital<br />

signs of the planet (King & Herring, 2000). Terra is a<br />

<strong>Earth</strong> Observing System (EOS), a National Aeronautic<br />

to gather data for developing models of climate and climate<br />

<strong>Earth</strong> System <strong>Science</strong><br />

Examining the list of vital signs being monitored by the<br />

5 Terra instruments (Table 1), one gains an appreciation<br />

of the <strong>Earth</strong> systems students should be learning about<br />

in schools. Scientists do not yet understand the causeand-effect<br />

relationships among <strong>Earth</strong>’s lands, oceans,<br />

and atmosphere well enough to predict what, if any,<br />

impacts these rapid changes will have on future climate<br />

conditions. Scientists need to make many measurements<br />

all over the world, over a long period of time, in<br />

order to assemble the information needed to construct<br />

accurate computer models that will enable them to<br />

forecast the causes and effects of climate change. These<br />

new activities have focused our attention on ‘<strong>Earth</strong> System<br />

<strong>Science</strong>’.<br />

In <strong>Earth</strong> system science, the planet <strong>Earth</strong> is viewed as<br />

evolving as a synergistic physical system of interrelated<br />

phenomenon, processes and cycles. Given the concerns<br />

that humankind is impacting <strong>Earth</strong>’s physical climate system,<br />

a broader concept of <strong>Earth</strong> as a system is emerging.<br />

Within this concept, knowledge from the traditional <strong>Earth</strong><br />

science disciplines of geology, meteorology and oceanography<br />

along with biology is being gleaned and integrated to<br />

form a physical basis for <strong>Earth</strong> system science.<br />

This concept of the <strong>Earth</strong> as a complex and dynamic<br />

entity of interrelated subsystems implies that there<br />

is no process or phenomenon within the <strong>Earth</strong> system<br />

that occurs in complete isolation from other elements<br />

of the system.<br />

The initial views of the <strong>Earth</strong> Systems (ES) approach<br />

to <strong>Earth</strong> science education emerged from a conference<br />

that brought science educators and Bretherton Report<br />

geoscientists together in Washington DC in April 1988.<br />

The core issue was to abandon “the reductionist<br />

approach of focusing on the specific contributions of<br />

certain scientific disciplines in understanding concepts<br />

and process with their defined domain and replace it<br />

with a curriculum framework that relates the concepts<br />

and processes “to the <strong>Earth</strong> system in which they operate<br />

and interact with other processes and concepts”<br />

(Mayer & Armstrong, 1990; p 155).<br />

The problem is that whereas scientists function in<br />

interdisciplinary teams to pursue scientific inquiries<br />

(for example, more than 800 scientists from many disciplines<br />

are working on the numerous datasets collected<br />

by the Terra mission), our science education<br />

curriculum frameworks still honor the separate discipline<br />

model of <strong>teaching</strong> science. The move to <strong>Earth</strong><br />

systems, and thus to an integrated science approach,<br />

according to Mayer and Armstrong (1990) recognizes;<br />

(1) the need for curriculum to reflect our social and<br />

economic systems and the basic understanding of the<br />

nature of scientific investigation; (2) how science disciplines<br />

are now intimately intertwined; (3) mathematics<br />

as an essential tool of modern science; (4)<br />

application of science in industry and global developments;<br />

and (5) the need for citizens to understand how<br />

technology is used in our society, to see the role evidence<br />

has as the real authority in science, and to see the<br />

power of theories in the investigation of nature.<br />

<strong>Earth</strong> System Curriculum Frameworks<br />

In the decade following the 1988 conferences, there<br />

have been several significant developments in the<br />

www.esta-uk.org<br />

TEACHING EARTH SCIENCES ● Volume 26 ● Number 3, 2001<br />

design of <strong>Earth</strong> system science curriculum. A nontechnological<br />

focused approach is found in Mayer’s<br />

“<strong>Earth</strong> Systems Education” (Mayer 1991; Fortner,<br />

1991), which became manifest as PLESE (Program for<br />

Leadership in <strong>Earth</strong> Systems Education) (Mayer et. Al.,<br />

1992). Technological approaches to <strong>Earth</strong> systems science<br />

can be found in the K-12 GLOBE Program (Global<br />

Learning and Observation to Benefit the<br />

Environment) (Rock et al, 1997); and the Learning<br />

through Collaborative Visualization (CoVis) Project<br />

(Edelson, Gordin & Pea, 1999).<br />

PLESE emerged from a teacher enhancement initiative<br />

at Ohio State University funded by the National<br />

<strong>Science</strong> Foundation in 1990. Initial efforts within<br />

PLESE led to the formation of a set of core concepts<br />

considered prerequisite for a 21st-century view of planet<br />

<strong>Earth</strong>, and the set of seven understandings that constitute<br />

a framework for <strong>Earth</strong> systems education:<br />

Understanding 1. <strong>Earth</strong> is unique, a planet of rare beauty<br />

and great value.<br />

Understanding 2. Human activities, collective and individual,<br />

conscious and inadvertent, are seriously impacting<br />

planet <strong>Earth</strong>.<br />

Understanding 3. The development of scientific thinking<br />

and technology increases our ability to utilize <strong>Earth</strong><br />

and space.<br />

Understanding 4. The <strong>Earth</strong> system is composed of the<br />

interacting subsystems of water, land, ice, air, and life.<br />

Understanding 5. Planet <strong>Earth</strong> is more than 4 billion<br />

years old and its subsystems are continually evolving.<br />

Understanding 6. <strong>Earth</strong> is a small subsystem of a solar<br />

system within the vast and ancient universe.<br />

Understanding 7. There are many people with careers that<br />

involved study of <strong>Earth</strong>’s origin, processes, and evolution.<br />

The PLESE Project yielded <strong>Science</strong> as a Study of <strong>Earth</strong>: A<br />

Resource Guide for <strong>Science</strong> Curriculum Restructure (Mayer and<br />

Fortner, 1995) that educators could use to restructure<br />

their curriculum toward an <strong>Earth</strong> systems approach.<br />

GLOBE is a worldwide initiative to recruit schoolaged<br />

children in the gathering of data to help scientists<br />

develop models that will test the information contained<br />

in satellite images. UK teachers can learn more about<br />

GLOBE by visiting their website www.globe.org.uk<br />

Students in 9500 schools in 90 countries are currently<br />

part of the GLOBE effort. Students data-gathering and<br />

reporting protocols have been established for the areas<br />

of study outlined in Table 2. Participating schools collect<br />

environmental observations at or near their schools<br />

and report their data through the Internet. These data<br />

are added to NASA and NOAA global databases. Scientists<br />

use GLOBE data in their research and provide<br />

feedback to the students to enrich their science education.<br />

Global images based on GLOBE student data are<br />

displayed on the World Wide Web, enabling students<br />

and other visitors to visualize the student environmental<br />

observations.<br />

The CoVis project also focuses on the support of student<br />

inquiries. Employing powerful visualization tools<br />

similar to those used by scientists, students develop and<br />

test <strong>Earth</strong> system models. The CoVis researchers have<br />

so far developed the Climate Visualizer, the Radiation-<br />

Budget Visualizer, and the Greenhouse Effect Visualizer<br />

and the Worldwatcher which combines all the<br />

Visualizers (Edelson, Gordin & Pea, 1999).<br />

At the KS3 level, Worldwatcher Project www.worldwatcher.northwestern.edu<br />

students learn about the<br />

scientific factors that contribute to the controversial<br />

global warming debate. The project places students as<br />

advisors to the heads of state of several different<br />

nations, prompting students to learn about the issue as<br />

they respond to the various questions and concerns of<br />

these leaders. As expert scientists on the issue, the class<br />

is challenged to understand and explain to the heads of<br />

state what forces affect climate and what global warming<br />

actually means. Once they do this, they are asked to<br />

help the different nations of the world understand how<br />

global warming will affect them and what they can do<br />

about it. Each student team advises one country and<br />

presents a proposal that offers a set of solutions which<br />

address the concerns of their country. Stages of the project<br />

include an introduction to the basic issues of global<br />

warming, understanding the factors that contribute<br />

to temperature change, investigating the factors that<br />

determine global temperature and energy use, understanding<br />

potential consequences of atmospheric pollution<br />

on global climate, and finding solutions to these<br />

types of problems.<br />

environmental science curriculum centered on three<br />

key issues: Populations, Resources, and Sustainability;<br />

will use throughout the curriculum. They begin to<br />

wrestle with the problems of sustainability as they<br />

investigate the growth in human population and<br />

resource usage.<br />

The second component of the curriculum centers<br />

on the issue of how a community will meet the increasing<br />

demand for electricity. The third portion of the curriculum<br />

focuses on organism interaction, plant<br />

adoption strategies, and impacts on the ecosystem due<br />

to resource allocation in the Mojave Desert and Great<br />

Central Valley in California. A fourth component of the<br />

curriculum allows students to apply what they have<br />

learned to their own local area. The activities that make<br />

up this unit are interwoven with the other three units<br />

over the entire year.<br />

<strong>Earth</strong> science Pedagogical Practices<br />

The structure of knowledge, the epistemic goals and<br />

data-gathering processes within the <strong>Earth</strong> sciences<br />

afford certain opportunities for learning science, learning<br />

about science, and learning to do science. The challenge<br />

is one that resides in the dual agenda of science<br />

education – learning what we know vs learning how we<br />

come to know and why we believe it. The challenge<br />

represents the balance that is sought in the curriculum<br />

between learning, on the one hand, the canonical<br />

knowledge of scientific disciplines (what we know)<br />

and, on the other hand, the epistemic structures and<br />

social and economic application issues that arise during<br />

engagement in science-in-the-making activities and<br />

inquiries. The new <strong>Earth</strong> system database and technological<br />

resources coupled with the new <strong>Earth</strong> science<br />

systems framework, make possible project-based science<br />

and extend inquiry-based opportunities not otherwise<br />

as easily attainable in other disciplines.<br />

Furthermore, the global, national, regional and local<br />

environmental perspectives associated with <strong>Earth</strong> system<br />

science have the potential to situate the subject<br />

matter in meaningful and relevant contexts of study.<br />

The implication is that inquiry instructional methods<br />

employing model-based learning and reasoning activities<br />

establish the grounds for best practices in the<br />

<strong>teaching</strong> and learning of the <strong>Earth</strong> sciences.<br />

The recent focus on science enquiry in the National<br />

Curriculum (Scheme 1) suggests previous efforts to<br />

infuse inquiry <strong>teaching</strong> approaches into science programs<br />

have not made inroads on science education<br />

practices. New research results have begun to shift the<br />

perspective away from final form science to a perspective<br />

of ‘science-in-the-making’. Driven by a consideration<br />

of the revisionary nature of the growth of scientific<br />

knowledge and coupled with analyses of the cognitive<br />

and social practices of scientists, it is not surprising that<br />

the focus has been on engaging learners in the conversations<br />

and languages of science. During science-inthe-making<br />

episodes, debates and arguments about<br />

representations, models, evidence, theories, methods,<br />

aims, are played out.<br />

The <strong>Earth</strong> system science frameworks outlined<br />

above can provide rich contexts for inquiry learning.<br />

<strong>Earth</strong> system science is well suited to promote inquiry<br />

conversations.<br />

Working with <strong>Earth</strong> system science frameworks<br />

Edelson et al (1999), have developed a set of curriculum<br />

design strategies for planning and delivering inquirybased<br />

instruction and learning. The strategies include<br />

(1) using meaningful problems to establish motivating<br />

contexts for inquiry, (2) using staging activities to introduce<br />

learners to background knowledge and investigative<br />

techniques, (3) using bridging activities to bridge the<br />

gap between the practices of students and scientists, (4)<br />

using scaffolds that embed tacit knowledge of experts in<br />

supportive user-interfaces; (5) providing a library of<br />

resources as an embedded information source; and (6) providing<br />

record-keeping tools which allow students to record<br />

procedures and store products generated.<br />

In my own work, (Duschl and Gitomer, 1997) on<br />

formative assessment learning environments we have<br />

developed a whole class instructional strategy called<br />

‘assessment conversations’. Here teachers select<br />

examples of student work that reflect the diversity of<br />

thinking or diversity of strategies. Then, the work is<br />

shared and discussed to expose what the students were<br />

thinking and what strategies were used to complete<br />

the task. In this process of formative assessment, students<br />

learn from seeing others’ ideas. The role of the<br />

teacher is to choose the work that leads to attaining the<br />

goals of the lessons. The five key features of our<br />

approach to inquiry are (1) situating the curriculum<br />

unit in a meaningful problem solving context, (2)<br />

encouraging students to use multiple ways of showing<br />

understanding (e.g., drawings, labeled diagrams, writing,<br />

etc.), (3) engaging learners in the public consideration<br />

of ideas (e.g., assessment conversations), (4)<br />

employing formative assessment practices in three<br />

domains – conceptual learning, representational<br />

learning, and epistemic learning; (5) using scientific criteria<br />

and curriculum goals as organizing principles to<br />

evaluate knowledge claims.<br />

Implications for Instruction<br />

The <strong>Earth</strong> system science framework and the inquiry<br />

models proposed by Mayer, Edelson, and myself challenge<br />

ideas about the content of <strong>Earth</strong> science courses.<br />

One shift is moving from the construction of scientific<br />

knowledge claims to the construction and evaluation of<br />

scientific knowledge claims. Another shift is from independent<br />

activities that verify conceptual relationships to<br />

sequences of activities/lessons that build and test conceptual<br />

models and inform decisions about subsequent<br />

inquiries and designs of investigations.<br />

The availability of global databases and investigative<br />

and communication tools coupled with the relevance of<br />

environmental issues and the problems of sustainable<br />

development enable the K-12 <strong>Earth</strong> science curriculum<br />

to occupy a privileged position in science education.<br />

Geology and the Human Environment:<br />

The Nuclear Waste Problem<br />

OWAIN THOMAS<br />

This paper was delivered as a workshop at the Annual Conference of the <strong>Earth</strong> <strong>Science</strong> Teachers<br />

<strong>Association</strong> at Kingston University in September 2001. It describes a Study Day set up at the<br />

National Museum and Gallery of Wales for AS Geology students. The core exercise requires<br />

students to engage with the basic spatial, geological and environmental issues which lie behind<br />

the decision to locate a nuclear power station.<br />

Introduction<br />

The National Museum and Gallery of Wales has an<br />

excellent record of supporting education throughout<br />

Wales. The Education Department is responsible for<br />

developing resources to complement the displays,<br />

including the superb “Evolution of Wales” exhibition.<br />

About eighteen months ago I suggested developing<br />

some educational resources to support the new AS/A2<br />

level specifications. Geraint Price, the Senior Education<br />

Officer was very keen to support the initiative and he<br />

worked with both Museum and Cardiff University<br />

staff to put together a study day for AS Geology students.<br />

I contributed a set of worksheets to complement<br />

the presentation made by the experts.<br />

We aimed to bring together as many aspects of the AS<br />

course as possible in an integrated problem-solving<br />

exercise and to meet this aim we developed the idea of<br />

choosing a suitable site for a nuclear waste facility on<br />

the imaginary South Pacific island of Nova Cambria.<br />

The study day<br />

Two groups of students attended the Museum for the<br />

study day in November 2000, one group from<br />

Amman Valley School, the other from Coleg Sir Gar<br />

(Carmarthenshire College) accompanied by their<br />

teacher, Dr. Liz Richards. Geraint Price arranged for a<br />

number of experts to give short presentations to the<br />

students, with each presentation being followed by a<br />

practical exercise. Dr Bob Owens and Sarah Chambers<br />

led respectively sessions on rock specimen identification<br />

and the use of fossils for relative dating.<br />

These were followed by Prof. Mike Bassett discussing<br />

fossil evidence for plate tectonics. Geraint contributed<br />

two sessions, one on volcanic hazards the other on<br />

groundwater processes. Dr Carolyn Heeps from the<br />

Education Department analysed the erosion and<br />

depositional processes affecting coasts. <strong>Earth</strong>quake<br />

hazards and monitoring was covered by Dr Pete Brabham<br />

from the University and his colleague, Dr<br />

Charles Harris, finished the day with a session on site<br />

investigation techniques.<br />

I think that the day was very successful. The students<br />

felt that the sessions were very interesting and provided<br />

a lot of interesting background information, despite the<br />

fact that we had tried to cover a great deal of material in<br />

the single day. The practical aspects were particularly<br />

popular with the students.<br />

Geraint Price and I decided that we would try to<br />

develop the materials so that they could be used in a<br />

number of different ways. The pack can be used in<br />

schools using specimens readily available in a standard<br />

departmental collection. Alternatively, materials can be<br />

borrowed from the Museum’s outreach collection and<br />

it is anticipated that the study day will be repeated at<br />

some point in the future.<br />

The activity pack<br />

The intention is that the pupils will practise a number<br />

of skills as they work their way through this pack,<br />

including:<br />

● rock specimen description and identification;<br />

● fossil identification;<br />

● cross-section drawing;<br />

● locating earthquake epicentres;<br />

● interpreting volcanic monitoring data;<br />

● calculating rates of coastal erosion;<br />

● determining permeability;<br />

● interpreting geophysical survey data.<br />

Each of the above activities is introduced to the students<br />

assuming relatively little prior knowledge.<br />

It is suggested that teachers begin by giving the students a scenario:<br />

The island of Nova Cambria is in the southern Pacific Ocean, approximately 1000 km east of<br />

New Zealand. Generating electricity is a major problem on the island because, at present, it<br />

has no accessible fossil fuel reserves. Mining was carried out in the past but the mines were<br />

abandoned long ago and mining records have since been lost. For many years the islanders<br />

have relied on imported fossil fuels, but this is now very expensive. Recently a deposit of<br />

uranium ore has been discovered and the island Government has decided to use it to generate<br />

electricity in a nuclear power station. The power station has been constructed but the problem<br />

is to find a suitable site for the storage of radioactive waste.<br />

The islanders have selected five possible sites. Your job is to use the geological data on the<br />

island to evaluate these sites and to choose the most appropriate location for the waste<br />

facility. Alternatively you can choose to abandon the project altogether.<br />

See Figures 1 and 2 which provide the spatial context<br />

for the decision-making exercise.<br />

The following Activities 1 - 6 are intended to show the<br />

students that some of these sites are unsuitable for<br />

locating a nuclear waste facility. As they proceed<br />

through the pack, it is envisaged that they will progressively<br />

eliminate some of the sites. Eventually they will<br />

be left with a few possibilities from which they must<br />

choose, justifying their proposals.<br />

Activity 1 - Background<br />

The first activity asks students to think about the social,<br />

economic and geological factors associated with siting<br />

the facility - this is merely “setting the scene”. Hopefully<br />

the students will be able to assess the impact of the<br />

waste facility on island life.<br />

Activity 2 - The geology of the island<br />

In this exercise, the students are provided with a set of<br />

five specimens to describe and identify. These specimens<br />

correspond to the five potential sites. Fossils are<br />

included among the specimens and the pupils should<br />

compare them with the stratigraphic column in the<br />

pack. The fossils can be used to determine the relative<br />

ages of the sedimentary rocks. Dip arrows shown on the<br />

outline map can be used by the pupils to draw a simple<br />

cross-section (see Fig 2).<br />

Activity 3 - Plate tectonic setting<br />

This section covers the hazards associated with living in<br />

a tectonically active region. <strong>Earth</strong>quakes generated in<br />

the nearby collision zone may affect the island and the<br />

students are asked to plot the epicentre of earthquakes<br />

using seismograms. Volcanic monitoring data from the<br />

island is given and the students should try to interpret<br />

the significance of the measurements.<br />

Activity 4<br />

One of the proposed sites is located near the coast (see<br />

Fig 2). This activity examines the hazards posed by<br />

coastal processes; using historical coastline positions<br />

students can calculate the mean rate of erosion. If a<br />

sample of volcanic sand is available, the process of longshore<br />

drift can also be discussed.<br />

Activity 5<br />

Students can use the specimens to investigate permeability.<br />

This is an important factor in the choice of location<br />

since it is important to eliminate the chance<br />

radioactive material being transported by percolating<br />

groundwater. There are also several surface watercourses<br />

on the island, many near population centres.<br />

Activity 6<br />

Site investigation techniques are used prior to any<br />

major civil engineering project. Two examples of site<br />

investigation data are given and the students use these<br />

to locate subsurface problems in the region of one proposed<br />

site.<br />

Finally, the students are expected to fill in a short<br />

report, identifying the most appropriate choice and justifying<br />

their selection.<br />

Using the pack<br />

Geraint Price and his colleagues at the Museum have<br />

worked towards publishing this resource pack on the<br />

Internet, financially supported by the Curry Fund. It is<br />

intended that readers will be able to download the pack,<br />

(including a teachers’ guide with suggested answers)<br />

directly from the Museum’s website.<br />

Feedback<br />

The pack was presented to delegates at the ESTA 2001<br />

Annual Conference at Kingston University and we<br />

were delighted with the positive feedback on the activities.<br />

In addition, some suggestions were made for<br />

improving and developing the pack further and I am<br />

very grateful to everyone who contributed. If any readers<br />

use the pack in their <strong>teaching</strong>, feedback would be<br />

greatly appreciated.<br />

Iron Ore Formation:<br />

A Laboratory Model<br />

JOHN MOSELEY<br />

Geochemical processes are not easy to replicate. Actual time, temperature, pressure and pH-Eh<br />

levels can be difficult to reproduce accurately in a school laboratory. However, an interest in<br />

small-scale hematite deposits in Charnwood Forest (Leicestershire), South Shropshire, and the<br />

well-known iron ore deposits of the Forest of Dean, Gloucestershire has stimulated the<br />

development of some simple laboratory models. This investigation can be used to develop<br />

interesting and perhaps contentious discussion on geochemical processes as well as providing<br />

material for ‘A’ level geology course work.<br />

Figure 1<br />

The Precambrian<br />

geology of<br />

Charnwood Forest<br />

Geological Background<br />

The very late Precambrian to early Cambrian Charnian<br />

Supergroup of Charnwood Forest is overlain unconformably<br />

by red Triassic breccias, sandstones and mudstones.<br />

Field evidence and geochemical analyses show<br />

that more silicic rocks, silicified rhyolitic volcanics and<br />

quartz arenite sandstones are all preferentially hematised<br />

(Moseley 1994). The strong, slaty cleavage that<br />

penetrates all Charnian rocks provides structural planes<br />

that are stained, or carry thin deposits of hematite. Pale<br />

grey rhyolitic dust tuffs low in the succession carry a<br />

reddish hematite signature while quartz-rich sandstones<br />

from the Brand display thin hematite deposits<br />

along joint and cleavage planes. Cracked quartz phenocrysts<br />

in some of the porphyries (Whitwick) Complex<br />

of northwest Charnwood are an attractive red<br />

colour where hematite fills fractures (see Figure 1).<br />

Figure 2: Geology of South Shropshire<br />

Localities where rocks have been hematized<br />

1. Manstone Rock; 2. The Knolls; 3. Myndtown; 4. Wart hill<br />

In South Shropshire the Stiperstones Quartzite of<br />

the Ordovician Shelve inlier and Precambrian Uriconian<br />

Volcanic Group of The Knolls and Wart Hill<br />

inliers display some small scale hematisation, as do<br />

Longmyndian sandstones near Myndtown and<br />

Caradocian sandstones near Wart Hill (Moseley<br />

1994). There is no red bed cover here, but red Triassic<br />

strata crops out 20 km to the north. These strata might<br />

once have extended further south but have since been<br />

removed by erosion (see Figure 2). Sparse hematite<br />

deposits near Manstone Rock on the Stiperstones have<br />

some malachite and azurite associated with them and<br />

the possibility of derivation from weathering of traces<br />

of chalcopyrite associated with the sulphide-barite<br />

deposits of the overlying Mytton Flags Formation<br />

should not be overlooked.<br />

Figure 3:<br />

The Carboniferous Crease Limestone and Coal<br />

Measure sandstones of the Forest of Dean (see Figure<br />

3) display some intense hematisation (Lowe 1993, King<br />

1998, Moseley 2000). These deposits were once extensively<br />

worked, and views differ on their origin. Weathering<br />

of either red Triassic strata or pyritous Coal<br />

Measure shales and coal probably sourced the iron.<br />

Speliogenesis might have accompanied hematisation as<br />

acidic, iron-bearing solutions descended and circulated.<br />

A pleasant walk of 500 metres westwards from the<br />

south end of Cannop Ponds along a forest track brings<br />

one to the memorial for miners lost in the Union Colliery<br />

disaster of 1904 (see Figure 4). Close by is a small<br />

privately owned drift mine. Pyritous shale waste can be<br />

seen here, already limonite stained due to pyrite<br />

decomposition. At the entrance to the nearby Slade Hill<br />

quarry, large joint-bounded sandstone blocks carry<br />

hematite deposits up to 2 cm thick.<br />

A Laboratory Model<br />

The interpretation of British hematite deposits is that<br />

iron-bearing solutions derived from weathering of a red<br />

bed cover, or pyrite rich rocks (King 1998, Lowe 1993),<br />

or as in the Furness deposits (Rose and Dunham 1977),<br />

from a volcanic source, have circulated laterally and/or<br />

downwards, and deposited iron oxides in silicic or carbonate<br />

rocks. Unweathered source rock material is<br />

unproductive for generating solutions for laboratory<br />

shale and red Triassic sandstones stirred thoroughly<br />

with water can provide iron containing solutions.<br />

Aqua-ion chemistry (see Table 1) shows that iron<br />

in solution generates and maintains acid conditions.<br />

The pH and iron (III) concentration of the solutions<br />

described above can be determined by titration (see<br />

Photograph). As iron (III) concentration controls<br />

acidity (pH) rather than anion concentration (e.g.<br />

sulphate ion from oxidation and weathering of pyrite)<br />

iron (III) chloride can be employed at appropriate<br />

concentrations to replicate natural solutions. Samples<br />

of crushed pyritous shales produced solutions where<br />

hydroxonium ion concentration is 10 -4 M to 10 -5 M, or<br />

pH of 4-5, so 0.027g to 0.0027g of hydrated iron chloride<br />

dissolved in 1000 cm 3 H 2 O provides an appropriate<br />

concentration range for iron (III) and<br />

hydroxonium iron concentration.<br />

Different rock types and minerals can then be<br />

immersed in various iron-containing solutions. Even<br />

very dilute solutions (e.g. 10 -5 M iron (III) ions) over a<br />

few days react with carbonate rocks which develop a<br />

hydrated iron oxide coating. Unexpectedly (but much<br />

more slowly) sandstones can also develop iron oxide<br />

coatings (see discussion). Non-pyritous shales and<br />

mudstones show no reaction.<br />

This investigation is appropriate for laboratory based<br />

‘A’ level geology coursework. Depending on the range<br />

of concentrations for iron-bearing solutions, one to two<br />

hours should be allowed for initial setting up. Small<br />

hand specimens can be allowed to stand in solutions in<br />

250 ml. beakers. Reactions should be observed regularly<br />

over a one to two week period.<br />

Safety: Protective goggles should be worn at all<br />

times, due to acidic solutions used.<br />

Discussion<br />

Various discussion topics can be developed from the<br />

model described above. For example: Does the model<br />

replicate natural processes? If so, what are the geochemical<br />

reactions? This question may also appeal to ‘A’<br />

level chemistry students who have some appreciation of<br />

aqua-ion activity.<br />

The role of weak acids in speliogenesis is well<br />

known (Lowe 1993). Strong acids are those almost<br />

completely dissociated to give a high hydroxonium<br />

ion concentration. Weak acids undergo a small degree<br />

of dissociation to give low hydroxonium concentration.<br />

The aqua-ion model implies the development of<br />

strong acid conditions (Lowe and Gunn 1995) as<br />

limestone was rapidly attacked with the subsequent<br />

deposition of iron oxides. This can promote discussion<br />

on the possibility of speliogenesis not always<br />

being a slow process where limestones are overlain by<br />

pyritous sediments.<br />

Preferential mineralization is well documented if<br />

not always fully understood. Mineralogically more simple<br />

rocks often seem more susceptible to mineralization<br />

processes.<br />

The susceptibility of carbonate rocks to acid attack<br />

means that, not surprisingly, iron ore deposition has<br />

occurred in these rocks (Moseley 2000). Hematisation<br />

of silicic rocks is less easily explained. There is the possibility<br />

of attraction between positive dipoles on<br />

aqua~ions and negatively charged SiO4 4- units (Moseley<br />

1994), an association hinted at in the variety of<br />

quartz called citrine. Much research remains to be done<br />

in this field.<br />

Developing Observational Skills for Geoscience Fieldwork:<br />

A Web-based Teaching Exercise<br />

PAMELA MURPHY<br />

Introduction<br />

The use of field notebooks is a mainstay of geoscience<br />

<strong>teaching</strong>: most geologists would consider keeping an<br />

accurate field notebook, with data and observations in<br />

the form of both notes and field sketches, to be an<br />

essential skill. Assessment of fieldwork frequently takes<br />

two forms: the field notebook is used to develop and<br />

assess the observational skills of the student, through<br />

note taking and sketches; while field reports or assignments<br />

prepared after the fieldtrip are used to assess students’<br />

abilities to develop their ideas, apply their<br />

observations or put them into geological context.<br />

However, many students do not understand this<br />

emphasis on the notebook. Why do we assess their field<br />

notes when we don’t assess their lecture notes? Why do<br />

they need to make a sketch, when they have taken a<br />

photograph? Why should they make a sketch, when<br />

they can’t draw? Unless students understand the reason<br />

for the field notebook, and for field sketches, they are<br />

unlikely to make a good job of them. Although students<br />

can be shown examples of “good” field notebooks, they<br />

are more likely to learn what is required by undertaking<br />

exercises which ask them to decide for themselves what<br />

is good and bad practice, and to develop and use the<br />

necessary skills.<br />

Even if geoscience students understand the purposes<br />

of the field notebook and the importance of observational<br />

skills, many are still nervous about making<br />

observations in the field. Too often the notebook is<br />

treated as lecture notes rather than field observations.<br />

Field sketches should play a significant role in field<br />

notes but frequently student field sketches bear little<br />

relation to the actual outcrop. This is not through lack<br />

of artistic talent (which the students assume is the problem)<br />

but rather through lack of observation. The students<br />

need to develop their confidence in making field<br />

sketches, and to understand that it is in fact a skill that<br />

can be learnt.<br />

Work in the field is limited by constraints of time and<br />

expense. Developing in the classroom before a trip<br />

begins the skills and confidence necessary for fieldwork<br />

ensures that the students will gain as much as possible<br />

from their time in the field. To address these problems,<br />

an online <strong>teaching</strong> exercise has been developed. This<br />

can be accessed at www.kingston.ac.uk/esg/fieldwork<br />

The exercise is designed to teach students the reasons<br />

which underpin the tasks they are being asked to<br />

do, as well as to teach them the skills they need to produce<br />

a good field notebook. It therefore seeks to explain<br />

the reasons for field notes being recorded in certain<br />

ways: for example, the reason why an orientation and a<br />

scale are important on a field sketch, or indeed why a<br />

field sketch is required at all. The aim is to promote<br />

deeper understanding through practice and evaluation.<br />

Development<br />

Why on the web?<br />

A web-based exercise seemed ideal for this project<br />

because it is flexible, allows the use of photographs, and<br />

text and graphic explanations can be added where necessary.<br />

Websites comprise an attractive format for students,<br />

making it more interesting than a normal,<br />

paper-based exercise. The students can spend as long as<br />

necessary on each part of the assignment and can access<br />

it from university or school computers or from home.<br />

Little or no introduction or contact <strong>teaching</strong> time is<br />

needed. The web-based format also allows the resource<br />

to be shared between institutions.<br />

Who is it aimed at?<br />

The site was designed for Level One degree students,<br />

but it can also be used for A or AS Level students. Very<br />

little specific prior knowledge is assumed, and text and<br />

graphic explanations are included to cover, for example,<br />

normal versus reverse faulting, sedimentary way-up<br />

structures, or en echelon vein sets.<br />

How does it work?<br />

The exercise has been created as a fairly simple website,<br />

using HTML and javascript, and can be accessed using<br />

any appropriate web browser (e.g., Netscape or Internet<br />

Explorer). The site can also be copied to CD and then<br />

accessed in the same way. The website uses a framesbased<br />

layout. Although frames are often discouraged<br />

for web sites, because they can confuse navigation and<br />

search engines, in this case there should be no need to<br />

“search” the pages. When a link is followed, the lefthand<br />

frame loads the text or explanation page, while the<br />

right hand frame loads a graphic example (see Figure1).<br />

It was decided that use of online assessment would<br />

limit the exercises to multiple choice, short answer or<br />

drag-and-drop labelling exercises, preventing practice<br />

in drawing. Instead, a worksheet (in the form of a Word<br />

document) can be downloaded, printed out and completed.<br />

The worksheet has space for individual answers<br />

and diagrams, and a marking scheme.<br />

Features<br />

Photos<br />

The website is illustrated with numerous photographs of<br />

outcrops and geological features. These were mainly taken<br />

If you are unsure about how to work out and mark the fault<br />

movement, click below for an explanation.<br />

EXPLANATION<br />

Normal Fault<br />

Extensional: rocks are<br />

pulled apart and upper<br />

block slides downwards<br />

Reverse Fault<br />

Compressional: rocks are<br />

squeezed together and upper<br />

block moves upwards. (Also<br />

called a thrust fault)<br />

Strike-slip Fault<br />

Rocks move horizontally. There<br />

may be a component of normal<br />

or-reverse movement:<br />

(oblique-slip) (Also called a<br />

wrench or tear fault)<br />

knowledge of the regional geology is not necessary.<br />

Many of the photographs are active, and clicking on them<br />

allows users to zoom in for more detail of particular sections.<br />

In some examples, moving the mouse over a photo<br />

or graphic will bring up explanations of certain areas.<br />

Frequently Asked Questions<br />

The website is set out in fairly informal language, and<br />

uses the common web format of a FAQ (or Frequently<br />

Asked Questions) page to explain the background and to<br />

answer students’ common questions about notebooks.<br />

Examples include why they are being asked to draw<br />

things, or why some teachers or lecturers insist that they<br />

“ink in” their field notebook, while others insist they do<br />

nothing to it at all once they leave the field.<br />

Explanations<br />

Very little prior knowledge is assumed, and explanations<br />

are given of the geological features in the examples. For<br />

example, alongside an exercise requiring students to<br />

draw a diagram from a photograph of a fault, and to<br />

work out and mark the direction of movement, there is<br />

a link to a page explaining fault movement, and reverse<br />

versus normal faulting (see Figure 1). In another example,<br />

a labelled diagram of a fold shows features such as<br />

axial planar cleavage: students are asked to produce a<br />

similarly labelled diagram from a photo of another fold,<br />

identifying similar key features (see Figure 2).<br />

Simple animated graphics have been created to<br />

demonstrate dynamic processes, such as refolding of<br />

folds or the production of curved mineral fibres in<br />

veins through shearing.<br />

Exercises<br />

The students are asked to download and complete the<br />

workbook. Some of the exercises require short textual<br />

answers, such as:<br />

● Explaining which of several methods of data recording<br />

is the best<br />

● Assessing the quality of examples of work from field<br />

notebooks by listing good and bad points<br />

● Listing the important features of an outcrop from a<br />

photograph.<br />

However, most of the exercises require students to produce<br />

a labelled diagram from a photograph. The aim of<br />

the task is not simply to copy the photograph: the diagram<br />

must be labelled, and it must contain information<br />

such as the direction of movement on a fault or the<br />

way-up of sedimentary structures. The students are<br />

therefore being asked not only to make observations<br />

but also to interpret them.<br />

A common problem when students are asked to produce<br />

field sketches is that they have no confidence in<br />

their drawing ability: they believe that they cannot draw.<br />

While there is no doubt that some people have a talent for<br />

drawing and others do not, many of the problems with<br />

student field sketches are the result of a lack of observation<br />

and care, rather than a lack of drawing ability. To<br />

overcome these problems, the students are taken<br />

through a sequence of steps, beginning with the decision<br />

whether or not a field sketch is necessary. It they decide<br />

to proceed with a field sketch, they have to identify its<br />

purposes (what the sketch is meant to show) before they<br />

begin to draw. They are then taken through the steps of<br />

adding labels, details, orientation and scale. In all cases,<br />

examples are given to illustrate the points being made.<br />

There are also tips such as how to record angles or proportions<br />

by first imagining a grid over the outcrop.<br />

In one exercise, the students are asked to draw a<br />

number of folds, using the minimum number of lines<br />

(see Figure 3). The point of this task is to develop students’<br />

skills of concentration on accurate observation of<br />

Figure 3<br />

Example exercise:<br />

students are<br />

asked to draw the<br />

shapes of these<br />

folds, using a<br />

limited number of<br />

lines. This forces<br />

them to<br />

concentrate on the<br />

shapes of the<br />

folds, rather than<br />

shadows, fractures<br />

or colours.<br />

A<br />

C<br />

2 lines should be<br />

enough to show<br />

this fold.<br />

In this case, one<br />

of the beds has<br />

been weathered<br />

out, leaving a<br />

hole, but this<br />

does not affect<br />

the shape of the<br />

fold. Two or three<br />

lines should be<br />

enough to show it.<br />

B<br />

D<br />

Again, one or two<br />

lines should be<br />

enough. There is<br />

some minor<br />

faulting present,<br />

but for this<br />

exercise it is not<br />

important: it is the<br />

shape of the fold<br />

you are looking at.<br />

Take extra care<br />

with this example,<br />

as the shapes are<br />

complicated.<br />

2. Using as few lines as possible, draw the shapes of these folds (only use lines, not labels):<br />

VOLCANOES<br />

BAD AND GOOD?<br />

Published by the <strong>Earth</strong> <strong>Science</strong> Teachers<br />

Published by the <strong>Earth</strong> <strong>Science</strong> Teachers’ <strong>Association</strong> Registered Charity No. 1005331<br />

This issue of Teaching Primary <strong>Earth</strong> <strong>Science</strong> addresses aspects of the National Curriculum areas of<br />

Geography and <strong>Science</strong>. Activities involving ICT and Literacy skills are suggested. There is opportunity<br />

to include Atlas skills, Research skills, imaginative writing and discussion.<br />

Introduction- Some Background Information<br />

In this issue we intend to consider Volcanoes, not only as a hazard but also to draw attention to how<br />

they can benefit people as well.<br />

Most volcanoes, on land or at sea, are located at or near plate boundaries. (See Teaching Primary<br />

<strong>Earth</strong> <strong>Science</strong>, number 4 - winter 1993- Mountain Building).<br />

Some of the disadvantages<br />

Volcanic eruptions are usually very spectacular. The really explosive and dangerous eruptions make<br />

the headlines in the news. Many of the less spectacular ones do not. The character of volcanic<br />

eruptions are very varied. The variations are related to the chemistry and temperature of the molten<br />

rock (lava).<br />

Runny lavas flow easily away from the crater of the volcano rather than solidifying in or close to it.<br />

Dissolved gases within the lava escape easily and so pressure rarely builds up. As a result the<br />

volcanoes associated with this type of lava erupt with less violence, but usually more frequently. Even<br />

fast flowing lava rarely kills anyone, though it can cause serious damage to property. Volcanoes in<br />

Iceland, for example, are of this type.<br />

Sticky lavas trap gas more easily. They don’t flow as far before they cool and solidify. Sticky lavas<br />

often ‘plug’ the volcano which causes pressure to build up below the earth’s surface. Eruptions are<br />

usually more violent. They consist not only of lava but also lava droplets and solid bits of rock<br />

blasted into the air. These bits are varied in size from small ash fragments to big ‘bombs’ and<br />

‘blocks’. Ash fall out is not particularly deadly but it may cause damage to buildings as a result of<br />

ash overloading roofs and causing them to collapse. The eruption in 1991 of Mount Pinatubo in the<br />

Philippines was of this type.<br />

Sometimes dissolved gas from the erupting lava mixes with the ash to produce a dangerous red-hot<br />

cloud that travels rapidly down the side of a volcano usually causing death and damage. Poisonous<br />

gases associated with volcanic eruptions kill people. Generally the air is unpleasant with sulphurous<br />

gases smelling like bad eggs. The ash that settles on the side of a volcano may at a later occasion get<br />

swept down in a huge mudslide.<br />

A good detailed account of Volcanic Hazards can be found on the Internet:<br />

www.cotf.edu/ete/modules/volcanoes/vclimate.html


WINTER 2001 ● Issue 35 ● VOLCANOES – BAD AND GOOD?<br />

Published by the <strong>Earth</strong> <strong>Science</strong> Teachers<br />

Some of the advantages<br />

● Soils that form from weathered basalt lava and ash fragments are normally very fertile. Crops grow<br />

very well. Many people choose to live on the flanks of the volcano to take advantage of such soils.<br />

● Lava flows that enter the sea build new land. This has happened in Hawaii, for example.<br />

● Fragments often make good building materials<br />

● Useful mineral deposits such as diamonds and opal are associated with volcanoes.<br />

● In Iceland, water heated by molten rock is used for heating homes or for making electricity.<br />

● Volcanoes such as Mount Vesuvius in Italy are important tourist attractions.<br />

● The earth’s atmosphere and the water on it evolved from gases produced by volcanic eruptions.<br />

● Volcanic eruptions that happened over millions of years created the earth’s atmosphere that<br />

enabled life to evolve on <strong>Earth</strong>.<br />

Suggested Activities<br />

Raising awareness of Hazards Associated with Volcanoes<br />

It would be topical to look at volcano hazards at the time of a volcanic eruption that was being<br />

regularly reported in the news. Many less spectacular volcanoes don’t make the news. However you<br />

can obtain relevant information on current eruptions from the Internet. Look at information on Current<br />

Eruptions on the following sites<br />

http://volcano.und.nodak.edu/<br />

http://volcanoes.usgs.gov/<br />

Class exercise:<br />

Use a World Map poster to locate and mark the volcanoes that are currently erupting. This might be an<br />

ongoing exercise that can be updated throughout the school year. Also mark onto the World Map any<br />

volcanoes that the children actually know about or have visited.<br />

Class exercise:<br />

Encourage the children to bring in any mementoes from their holidays- photos or rock specimens<br />

relating to volcanoes. Make a class display.<br />

Class exercise:<br />

Start a class scrapbook of articles from newspapers and magazines about volcanoes.<br />

Use video clips to illustrate how volcanoes can be dangerous.<br />

Source of good video footage and commentary may come from News reports from the Main News or<br />

from BBC Children’s Newsround. Alternatively record programmes and documentaries relating to<br />

volcanoes.<br />

Obtain information from the Internet describing the hazards of an eruption.<br />

The following site has a very detailed account of the 1991 eruption of Mount Pinatubo:<br />

http://wrgis.wr.usgs.gov/fact-sheet/fs113-97/<br />

A class exercise using ICT Skills for older children:<br />

Using resources from the Internet, newspaper articles and video information word process a<br />

newspaper report about a volcanic eruption with attention to the dangers volcanoes present to people.<br />

For younger children:<br />

Read the following (above right) extract to the class to emphasis the dangers of volcanic eruptions.


WINTER 2001 ● Issue 35 ● VOLCANOES – BAD AND GOOD?<br />

Published by the <strong>Earth</strong> <strong>Science</strong> Teachers<br />

Mount Pinatubo in the Philippines, a volcano dormant for 600 years, erupted on June 12th 1991. Thunderous<br />

explosions, shot out a mushroom of ash estimated by some to be 24km high was heard 80km away. There was<br />

so much ash that it blotted out the sun and made it cold. The volcano made the ground shake (earthquakes)<br />

which also caused damage to buildings. The eruption caused panic among the residents of nearby towns and<br />

cities. Many people left their homes and tried to get away from the eruption. Rocks the size of tennis balls were<br />

thrown up to 50km from the volcano. The ash gradually fell out of the sky. A reporter flying over the area wrote<br />

that the surrounding mountains looked as if snow had fallen on them. The ash fell everywhere- on towns, roads,<br />

cars, fields, and people. In some places it was 35cm deep. The weight of the ash caused many buildings to<br />

collapse, killing more people than the eruption itself. Electricity, water and telephones all failed. People found<br />

it difficult to breathe with all the ash in the air. The air also stank from the sulphur rich gases that had been<br />

thrown out in the eruption. It was like a massive stink bomb had been let off. The ash that fell on them<br />

destroyed many crops growing in the fields. Heavy rain washed much of the ash away and turned it into huge<br />

mudflows. These travelled very quickly down the hillsides and destroyed many bridges , roads and buildings.<br />

Unfortunately many people were swept away and lost their lives.<br />

Discuss with the class the meaning of the words in bold lettering. List the variety of hazards described<br />

in the article.<br />

A class exercise:<br />

Imaginative writing: To write a diary of a person who lives near Mount Pinatubo during the time of its<br />

eruption in 1991.<br />

Encourage the class to write about what it was like during the eruption. They could write about what<br />

they could see, hear, smell and feel.<br />

How did they feel during the eruption?<br />

They could also write about the ways in which the eruption made everyday life difficult and dangerous<br />

for people.<br />

Raising awareness of some of the benefits Associated with Volcanoes<br />

Overleaf is a list of statements that highlight some of the advantages and disadvantages (good and<br />

bad features) of volcanic eruptions. The list includes many features that are not used in any of the<br />

previous suggested resources and activities<br />

Duplicate and enlarge the list, laminate and cut into individual statements. Have spare blank cards<br />

prepared.<br />

Group Exercise: Each group separates the statements into ‘ good’ and ‘bad’.<br />

Alternatively lead a class activity and place ‘good’ and ‘bad’ onto prepared posters of two volcanoes.<br />

As visual aids use a bottled water such as Volvic that comes from a volcanic region. Obtain some<br />

pumice from Boots. In both cases students should be able to suggest additional comments- good and<br />

bad that they have witnessed in the previous activities. They could be written onto blank cards and<br />

also added to the work.<br />

The Laki eruption in Iceland in 1783<br />

killed no people. People living nearby<br />

were able to get safely away.<br />

The Laki eruption of 1783 covered and<br />

destroyed two churches and 14 farms.<br />

Ash and the gas from the Laki eruption of<br />

1783 killed grass and crops.<br />

The ash from the Laki eruption thrown<br />

into the air blotted out the sun. It made it<br />

cooler. Crops could not grow very well.<br />

The gases from ancient volcanic<br />

eruptions helped to create the<br />

atmosphere on <strong>Earth</strong>.<br />

A volcanic eruption on the island of<br />

Heimaey, Iceland in 1973 added a lot of<br />

extra land to the island. It provided better<br />

protection to the harbour.<br />

Mount Pinatubo threw much sulphur<br />

dioxide gas into the air. Scientists believe<br />

this caused a 1o C fall in world<br />

temperatures for over 5 years.<br />

Some people think that bottled drinking<br />

water from volcanic areas contains<br />

minerals that are good for their health.<br />

In Iceland as a result of the Laki eruption<br />

of 1783, nearly all of the cows, sheep<br />

and horses died. Many people died of<br />

famine.<br />

Icelandic people quarry a volcanic rock<br />

called pumice. Pumice is sold to Boots<br />

the Chemists in England who sell it to<br />

people so that they can scrub themselves<br />

in the bath!!<br />

In Iceland they use hot rock moving under<br />

the ground to heat water. This is used to<br />

heat people’s homes, outdoor swimming<br />

pools and even to help make electricity.<br />

In many parts of the World, ash from<br />

volcanoes makes very rich, fertile soil.<br />

Crops grow very well in those soils. Today<br />

people are once more farming the sides<br />

of Pinatubo.<br />

Many people go on holiday to Iceland to<br />

look at the volcanoes. Especially those<br />

that are not erupting!<br />

The ash from volcanic eruptions can get<br />

into the engines of aeroplanes flying<br />

through it. This is very dangerous!!<br />

In 2001 a group of tourists visiting Mount<br />

Pinatubo were surprised to find that<br />

many animals such as deer and monkeys<br />

are now once again living in the area.<br />

Gold and silver may be formed in<br />

volcanic material.<br />

the geological elements rather than any “noise”. They<br />

have to draw the shape of the fold, and not get distracted<br />

by shadows, unimportant fractures or vegetation.<br />

Using the website<br />

The project was developed at Kingston University for<br />

first year students on a range of degree courses including<br />

Geology, Applied or Environmental Geology, Joint Honours<br />

Geology/Geography, <strong>Earth</strong> <strong>Science</strong>s and <strong>Earth</strong> and<br />

Planetary <strong>Science</strong>s. The original plan was for the students<br />

to complete the web-based exercise just before<br />

attending a week-long field course to South West England.<br />

However, the outbreak of Foot and Mouth in<br />

Spring 2001 meant that the field trip had to be delayed<br />

for several months. As a result, the exercise was not fresh<br />

in the students’ minds by the time they reached the field.<br />

However, references to the exercise were made during<br />

the fieldwork to remind them (and they often recognised<br />

sites of photographs, such as the refolded fold at Penally<br />

Point). The quality of field sketches did appear to have<br />

improved relative to previous years.<br />

Plagiarism<br />

A few students chose to copy off each other, rather than<br />

making drawings from the website photographs. This<br />

was fairly easy for the tutor to spot because the suspect<br />

pairs of drawings often looked almost identical but very<br />

different from the photographs! If the website was to be<br />

used purely within Kingston University, this problem<br />

could be avoided by using a learning management system<br />

(such as Blackboard (tm)) which can keep track of<br />

access by individual students. However, in this case the<br />

intention was to make the resource available to external<br />

users, so such a solution was not practical.<br />

Evaluation<br />

Students were asked to provide feedback via an anonymous<br />

questionnaire. Most completed the yes/no questions<br />

but many students did not select any of the<br />

optional comment boxes. The questions were:<br />

● How long did you spend on the assignment?<br />

40% 1-2 hours,<br />

50% 2-3 hours,<br />

10% >3 hours (usually 3 1/2 hours)<br />

● Do you think it will improve your field notebook<br />

skills?<br />

(100% Yes)<br />

● Did it help you to see the point of the field<br />

notebook?<br />

(95% Yes)<br />

● Other comments<br />

(tick-boxes, in order of positive responses)<br />

The explanations were useful (77%)<br />

It made me think about what I was doing (68%)<br />

It was easy to follow (50%)<br />

It was interesting (45%)<br />

I liked the fact that it was on the web (45%)<br />

I enjoyed it (32%)<br />

It took too long (27%)<br />

I had difficulty getting access<br />

to a computer to log on (18%)<br />

It was too difficult (9%)<br />

The website didn’t work properly (9%)<br />

I couldn’t download the workbook properly (9%)<br />

It was a waste of time (0%)<br />

It was too basic (0%)<br />

In the “open comments” section, several students commented<br />

on the flexibility provided by being able to<br />

complete the exercise in their own time. Interestingly,<br />

those who commented that the exercise had taken too<br />

much time said it took 2-3 hours, which is the normal<br />

length of time for a practical assignment. Their definition<br />

of “too long” is clearly different to the author’s!<br />

However, some commented that spending several<br />

hours logged in from home was expensive. In future, a<br />

few copies will be made available on CD to people who<br />

want to work from home.<br />

Conclusions<br />

The website format is ideal for <strong>teaching</strong> material such<br />

as this, when students can work at their own pace, and<br />

additional information can be provided. The indications<br />

are that such an approach is interesting to students<br />

and improves their performance in the field. The development<br />

time for such a project is large, however, and<br />

can only really be considered to be cost-effective where<br />

institutions can share software or where student numbers<br />

are large. It is for this reason that the website is<br />

being made freely available. Feedback from teachers or<br />

lecturers who use the website will be welcomed.<br />

The website is available at www.kingston.ac.uk<br />

/esg/fieldwork. Copies can also be made available on<br />

CD for a nominal charge. Enquiries or feedback should<br />

be addressed to Pamela Murphy (details below).<br />

Editor’s Note: The following extracts are reproduced, with minor editing, from “<strong>Earth</strong> <strong>Science</strong><br />

Activities and Demonstrations” by Mike Tuke, published by John Murray, with the kind permission<br />

of author and publisher. Three items are given here: Frost Shattering; Making Rock; and Making<br />

Layers. All worksheets may be reproduced for non-commercial class use provided due<br />

acknowledgement is made.<br />

Frost Shattering<br />

Purpose<br />

To show how the expansion of water when<br />

it freezes may break up rocks.<br />

Requirements<br />

Per group:<br />

● Small glass jar with screw-on lid (plastic<br />

containers often stretch rather than break)<br />

● Clear polythene bag<br />

● Access to a freezer<br />

Notes (refer to worksheet)<br />

This activity is a useful one for pupils to do<br />

at home, although some parents may object.<br />

Several methods for finding the amount<br />

of expansion of ice are given below. The<br />

change in volume is about 9%.<br />

1. Seal off the needle end of a syringe with<br />

quick-glue or sealant such as Araldite.<br />

Half fill the syringe with water and note<br />

the position of the plunger. To get the<br />

air out of the syringe insert a wire down<br />

the side of the plunger before pushing it<br />

in. Then place the syringe in the freezer,<br />

and when the water has frozen note<br />

how far the plunger has moved out.<br />

2. Fill a balloon with water, tie its top and<br />

measure its circumference. Freeze it,<br />

and when it is solid measure its circumference<br />

again.<br />

3. Place a plastic measuring cylinder threequarters<br />

full of water in the freezer.<br />

When frozen the top of the ice will be<br />

uneven but an average level can be<br />

found.<br />

Q2 Water gets into the cracks in rocks,<br />

freezes and expands. This widens the crack<br />

and eventually breaks the rock apart.<br />

Q5 The scree (or talus deposits) which<br />

covers many the hillsides in the Lake District<br />

is formed in this way.<br />

Q6 Rocks shattered by frost will be found<br />

at the top of mountains, where lowest temperatures<br />

occur<br />

Making Rock<br />

Purpose<br />

To show how sediments are turned into rock.<br />

Requirements<br />

Per pupil:<br />

● Bunsen burner<br />

● Old dessert spoon<br />

● Concentrated sugar solution<br />

● Level dessert spoon of sand<br />

● Teat pipette<br />

Notes (refer to worksheet)<br />

There are three methods for making rock.<br />

Only this one can be completed in a lesson<br />

but the following are in some ways better.<br />

Method 1. Take a bucket and nearly fill it<br />

up with builders’ sand. Saturate the sand<br />

with water and leave for several days. This<br />

works well in hard water areas such as southeast<br />

England. You can part-bury a penny in<br />

the sand to show that the rock is artificial.<br />

This is the most effective method because it<br />

uses normal water and produces large lumps<br />

of rock, but it is the least reliable.<br />

Method 2. Fill a margarine container<br />

with sand and a concentrated solution of<br />

common salt. Leave it to evaporate. The<br />

top surface will become quite hard.<br />

Q1 Common salt is soluble, so would be<br />

dissolved away by rainwater.<br />

Q2 Precipitation differs from evaporation<br />

in that the water is not driven off; the<br />

chemical compound ceases to be in solution<br />

but the water is still present.<br />

Q3 No-one has yet observed sugar solutions<br />

in the <strong>Earth</strong>, but solutions containing<br />

calcium carbonate and iron compounds<br />

are common. The compounds may be precipitated<br />

between the sand grains to<br />

cement’ the grains together to form rock.<br />

Making Layers<br />

Purpose<br />

To show why sedimentary rocks are layered.<br />

Requirements<br />

Per group often pupils:<br />

● Several types of sand and pebbles, some<br />

rounded and some angular, of various<br />

sizes and colours, in separate containers<br />

(see Notes)<br />

● Coffee jar one third full of water and<br />

with a layer of sand in it (see Notes)<br />

● Cups or bottle tops with a capacity of<br />

about 30 ml<br />

Notes (refer to worksheet)<br />

This is a very important concept to get<br />

over to pupils, but it is also fairly easy to<br />

understand. This activity is often best done<br />

as a demonstration but is also useful as an<br />

activity for low ability children. It is best to<br />

choose pebbles that can easily be separated<br />

again, unless you have sieves.<br />

About ten cupfuls of sediment are sufficient<br />

in one coffee jar. Take care that the<br />

water in the jar does not overflow and that<br />

pupils do not all choose the same sediment.<br />

Both of these problems can be<br />

avoided by having cups already filled with<br />

sediment which pupils can just tip in. In<br />

this case the amount in each cup can be<br />

varied to give different thicknesses of sediment.<br />

Sand should be the first layer and if<br />

it is used to make another layer it should be<br />

put onto pebbles about 2 mm across, to<br />

stop it sinking down and obliterating the<br />

lower layers.<br />

Q1 (a) and (b) would have taken many<br />

years, (c), (d) and (e) days. (f) months.<br />

Q2 Sediments found: peat (top and latest<br />

layer), shells, volcanic ash, pebbles, mud,<br />

sand, mud, sand, mud, sand (lowest and<br />

oldest layer).<br />

An <strong>Earth</strong> <strong>Science</strong> Fieldtrip<br />

for Key Stage 3 Pupils<br />

OWAIN THOMAS<br />

In a recent article in Teaching <strong>Earth</strong> <strong>Science</strong>s I described some activities that could be used in<br />

science courses in Key Stage 4 (<strong>Earth</strong> <strong>Science</strong> in Double Award <strong>Science</strong>, TES 26(1), 2001: 13-14).<br />

Of course, pupils’ learning at Key Stage 4 must build on their prior learning in Key Stage 3, so this<br />

article describes a simple field trip for Key Stage 3 pupils. The area is south west Wales in the<br />

vicinity of Saundersfoot on the Pembrokeshire coast.<br />

Figure 1<br />

Why bother?<br />

Many teachers of GCSE and A level geology are concerned<br />

with the numbers of pupils who choose the subject.<br />

For several years in Amman Valley School, the<br />

number of students taking A level geology has declined<br />

alarmingly and we felt that one way of improving the<br />

uptake of the subject was to provide younger pupils<br />

with a positive experience of <strong>Earth</strong> science. An obvious<br />

way of doing this was to provide a field trip, on the basis<br />

that in pupils’ minds any time out of school is a positive<br />

experience, by definition!<br />

Another reason for organising a field trip was to<br />

provide help for my colleagues in <strong>teaching</strong> some of the<br />

Key Stage 3 <strong>Earth</strong> science. This is taught as a module<br />

in Year 9 in the chemistry lessons. I teach with three<br />

colleagues in the chemistry department, all of whom<br />

have little or no background in <strong>Earth</strong> science. As a<br />

geology specialist working within the science faculty,<br />

it is clearly my responsibility to provide curriculum<br />

leadership in this field and thereby help to make the<br />

<strong>Earth</strong> science component as interesting as possible for<br />

pupils and teachers alike.<br />

Organisation<br />

Time for field trips is becoming more difficult to find in<br />

school because of timetable and exam constraints.<br />

However, we normally schedule the trip as close to the<br />

end of the Summer Term as possible (tides permitting).<br />

Pupils are accepted on a first come first served basis (we<br />

usually take only one bus load) and they only pay a contribution<br />

towards the cost of hiring the bus. <strong>Science</strong><br />

staff accompany the pupils in the ratio 1:15.<br />

TEACHING EARTH SCIENCES ● Volume 26 ● Number 3, 2001<br />

The activities<br />

The aim of this field trip is to stimulate interest in <strong>Earth</strong><br />

science rather than try to get them to learn lots of new<br />

ideas. The beach south of the harbour at Saundersfoot<br />

has a spectacular anticline (see front cover photograph)<br />

that clearly illustrates the ideas that sedimentary rocks<br />

form in layers and that these layers can be bent under<br />

pressure. The first activity (see Figure 1 Task 1) asks the<br />

pupils to draw the shape of the anticline and to decide<br />

on the type of rock it is made of (sedimentary, igneous<br />

or metamorphic). The quality of the field sketches is<br />

usually quite poor at first but at least it makes the pupils<br />

look at the rocks with a “scientific eye”. They examine<br />

the rocks (avoiding all possible hazards such as overhanging<br />

rocks) and estimate the dip of each limb.<br />

Approximately 50 metres back towards the harbour<br />

there is a small syncline in the cliff. This is much more<br />

difficult to spot, but once the layers have been pointed<br />

out the pupils can usually distinguish the structure. The<br />

pupils can appreciate from this that you can have “up”<br />

and “down” folds (see Figure 1 Task 2).<br />

In the same region there are some faults. This time a<br />

sketch is provided (see Figure 2 Task 3) and the pupils are<br />

expected to estimate the distance that the rocks have<br />

moved and to interpret this movement in terms of compression<br />

or extension. Initially they find this quite difficult<br />

but once the teacher has pointed out the sandstone marker<br />

bed they can easily identify the sense of movement.<br />

The final two activities involve simple observations on<br />

the sand and the pebbles found on the beach (see Figure<br />

2 Tasks 4 & 5). These exercises simply show the range of<br />

different materials that can be found in a small area and<br />

are designed to get pupils to think about their origins.<br />

I am planning to introduce a new activity for next<br />

year’s trip in which the pupils will measure and describe<br />

the ripples found in the sand. This will lead towards some<br />

new statements in the AQA double award syllabus.<br />

Conclusion<br />

Fieldwork is one of the great strengths of <strong>Earth</strong> science.<br />

Pupils can learn that science is all around us and we can<br />

“do science” in all of these environments - not just the<br />

laboratory. The pupils get a lot out of the experience<br />

and I feel that it is very worthwhile.<br />

If you are involved in <strong>teaching</strong> the <strong>Earth</strong> science component<br />

of the Key Stage 3 course, can you find a suitable<br />

site for a field trip like this? If, on the other hand, you are<br />

an <strong>Earth</strong> science specialist not involved in Key Stage 3<br />

science, why not offer your services to your colleagues?<br />

Further Thoughts – Where Next for ESTA?<br />

IAN THOMAS<br />

This brief article continues with the theme I started<br />

in my item “From the ESTA Chair” (page 87).<br />

Can we learn lessons from others? What potential<br />

partnerships might be developed? As I write the<br />

anticyclonic gloom is all pervasive. However, if we are<br />

to address one of the issues in Roger Trend’s last Editorial<br />

(TES 26/2) regretting the lack of interest (indeed<br />

outright avoidance) of meteorology in schools, few of<br />

those now leaving school will have the slightest idea<br />

what the label “meteorology” means, let alone its scientific<br />

basis. This is quite astounding when we live on a<br />

series of islands where changing weather is a national<br />

obsession. This is even more staggering when we are<br />

bombarded hourly by programmes, acres of newsprint<br />

and newsflashes on meteorological disasters, global<br />

warming, el Nino, the warmest October on record and<br />

so forth. Yet again, conditioned by the constraints of<br />

Exam Board specifications and the National Curriculum,<br />

many schools appear to be lagging behind developments<br />

(some of them longstanding) in the ‘real’<br />

World. This is perhaps even more remarkable still when<br />

one considers the emphasis for at least a decade on the<br />

environment – the main gap appears to be the unwillingness,<br />

inability or possibly fear of many involved to<br />

make the fundamental links between events and scientific<br />

explanations.<br />

Clearly ESTA cannot bite off more than it can chew<br />

– members are already stretched as they continue to<br />

make good progress in a wide range of fields. Just are we<br />

are improving <strong>Earth</strong> science <strong>teaching</strong> through an evergrowing<br />

network of partnerships, there may even be<br />

members willing to take this aspect further, for example<br />

by linking up with the Met. Office as it moves into its<br />

new home in Exeter.<br />

Broadening the theme a little further still, we might<br />

consider media coverage of the most popular, current,<br />

non-news issues of the day. In no particular order, these<br />

are likely to include: environmental matters; food and<br />

drink; art and design; and history/archaeology. ‘The<br />

environment’ can in turn embrace wildlife, major <strong>Earth</strong><br />

events, astronomy and at a stretch – dinosaurs. ESTA<br />

can rightly claim an interest in most of these. However,<br />

when set against the memberships of, for example, the<br />

National Trust, RSPB or county Wildlife Trusts, the<br />

number signing up for <strong>Earth</strong> science pales into insignificance.<br />

I may have missed a critical slot but David<br />

Attenborough’s recent highly-acclaimed Blue Planet<br />

series appeared to have little, if any, coverage of the<br />

most fundamental question of why the oceans are located<br />

where they are! Apart from the odd five minutes on<br />

black smokers, there was more on polar bears alone,<br />

although the piece on corals was instructive.<br />

Turning to another field, and bearing in mind that<br />

Sc4 ‘<strong>Earth</strong> and Beyond’ is virtually 100% ‘beyond’, it<br />

might be instructive to consider astronomy in a little<br />

more depth, or, as we should now term it, cosmology.<br />

On a recent cold Saturday night I joined about 200 others<br />

(some of whom had made an 80-mile round trip<br />

and including at least two school groups) outside, staring<br />

at a large video screen. For an hour nothing<br />

appeared to happen, but very few people left. It was too<br />

cloudy. Apparently it was equally cloudy at the two linkup<br />

stations in Portugal and Poland. Then, minutes<br />

before 9 pm, the clouds here began to break up as if to<br />

order, and we began to see on screen an eight-foot<br />

image of part of the Moon with a small but growing<br />

detached blob to the left – this was Saturn emerging<br />

from behind the Moon. With time, the image became a<br />

little clearer so that you just about pick out the planet’s<br />

rings. We were watching the ‘Occultation of Saturn by<br />

the Moon’. I would guess that 99.9% of the population<br />

have never heard of the term ‘occultation’ – yet this was<br />

how it was advertised and the press release (with the<br />

same title!) generated numerous calls for interviews<br />

with my colleague Rod Tippett (he has just been<br />

appointed honorary education officer for the Federation<br />

of Astronomical Societies).<br />

I want to mention two more examples. First, think of<br />

the room set in almost any American movie – a telescope<br />

is a prerequisite prop. Even more remarkable was<br />

news we received recently of people signing up for a<br />

luxury flight across southern Africa next year to watch<br />

the next major eclipse – at £10,000 each! There is not<br />

the slightest doubt that in the media, ‘astronomy’ is a<br />

magic world, yet you cannot even touch it.<br />

So what is it about <strong>Earth</strong> science in Britain which<br />

induces a Cinderella syndrome? Perhaps if we had<br />

more effective ways of predicting earthquakes or volcanic<br />

eruptions it might gain a little more popular<br />

appeal – not that we would witness too many of these<br />

events here. The British Geological Survey has made a<br />

step in the right direction in respect of the recent<br />

Melton Mowbray earthquake, by using a questionnaire<br />

in the press to solicit accounts of experiences of local<br />

people. Perhaps a selection of the results could be used<br />

in some new <strong>teaching</strong> materials?<br />

But this is hardly the real answer. I am sure that<br />

skilled and up-to-date presentation are critical factors –<br />

possibly one or two embryo Patrick Moores, David<br />

Attenboroughs and Tony Robinsons are now beginning<br />

to emerge but it is a very slow process – there is no<br />

magic bullet.<br />

However, considering its size, for many years ESTA<br />

has achieved much and continues to do so. With so<br />

much ground still to cover we can only do this, as I have<br />

always emphasised, through partnerships - with other<br />

institutions in the scientific community including universities,<br />

the other scientific institutions, the BGS, both<br />

New ESTA Members<br />

GAs, UKRIGS and, at some stage, those engaged in<br />

meteorology and cosmology. Should we extend our<br />

brief to cover what is conventionally called the public<br />

understanding of (<strong>Earth</strong>) science - which should perhaps<br />

more correctly begin with scientists better understanding<br />

the public. To do this effectively we do need a<br />

co-ordinated prioritised rolling plan covering, say, the<br />

next five years.<br />

POSTSCRIPT 1<br />

As I drew to a close, after days, the gloom outside has<br />

broken up to reveal an <strong>Earth</strong> scientist’s ‘to die for’<br />

panorama of sunset over the Matlock gorge – complete<br />

with dramatic folding, fault controlled features, a variety<br />

of rock types, classic mineralisation and, glacial geomorphology,<br />

but which most people see in perfectly<br />

valid terms effectively in one dimension as, ‘a nice view’<br />

(and I write as someone who has painted the scene a<br />

dozen times).<br />

POSTCRIPT 2<br />

Incidentally, has anyone tried recording the shipping<br />

forecasts – reports from coastal stations – over a number<br />

of days, then asking students to plot the returns to<br />

establish moving weather systems from real data – here<br />

is plenty of good science, mapwork, ICT and the added<br />

possibility of numeracy.<br />

An introduction to Atmospheric Physics by David G. Andrews<br />

Cambridge University Press, 2000, £17.95 (paperback), £50 (hardback).<br />

ISBN 0-521-62051-1.<br />

This book, as stated in the preface, is<br />

intended as an introductory text for<br />

third or fourth year undergraduates<br />

studying atmospheric physics, for<br />

graduate students studying atmospheric<br />

physics for the first time and for<br />

students of applied mathematics,<br />

physical chemistry and engineering who<br />

have an interest in the atmosphere. As<br />

such it assumes a basic knowledge of<br />

thermodynamics, electromagnetic<br />

radiation and quantum physics, together<br />

with some vector calculus. Its emphasis<br />

throughout is on the basic physical<br />

principles and their expression in an<br />

atmospheric context, rather than on a<br />

range of applications. Thus, it covers the<br />

three fundamental pillars of atmospheric<br />

physics – thermodynamics, radiation and<br />

fluid mechanics – with additional<br />

chapters on stratospheric chemistry,<br />

remote sensing and atmospheric<br />

modelling.<br />

The style of the book follows that of<br />

an earlier successful atmospheric physics<br />

text from an Oxford University author –<br />

Physics of Atmospheres by J. T.<br />

Houghton – in that an extensive list of<br />

problems follows each chapter which<br />

both illustrate the fundamental<br />

principles and introduce important<br />

applications. The problems will be<br />

indispensable to a serious student<br />

seeking to learn from this book and<br />

represent a valuable resource for<br />

<strong>teaching</strong> atmospheric science within<br />

physics courses. Solutions to each<br />

problem (and hints on how to obtain<br />

some of them) are provided at the end of<br />

the book.<br />

As expected from the target<br />

readership, the text concentrates on<br />

developing the basic equations of<br />

atmospheric physics from the first<br />

principles, explaining the many<br />

approximations and shortcuts that can<br />

make this branch of classical physics so<br />

confusing for undergraduates. Its remit<br />

is the <strong>Earth</strong>’s neutral atmosphere, from<br />

the ground to around 100 km altitude,<br />

which contains the weather and climate<br />

and the ozone layer as well as less<br />

familiar phenomena such as noctilucent<br />

clouds; it does not cover the ionosphere<br />

and magnetosphere.<br />

A short initial chapter introduces<br />

some essential terminology, presents the<br />

mean temperature and wind fields of the<br />

atmosphere and introduces some of the<br />

key phenomena (such as Rossby waves<br />

and the greenhouse effect) treated in<br />

detail in later chapters. This leads on to<br />

the second chapter, on atmospheric<br />

thermodynamics. The treatment here<br />

follows Houghton in introducing the<br />

tephigram – an invaluable graphical tool<br />

for representing the thermodynamic<br />

state of the troposphere, much used by<br />

meteorologists but often omitted from<br />

the basic text books. The introduction to<br />

cloud physics at the end of this chapter<br />

is rather short, and a reader interested in<br />

this subject will need to consult more<br />

specialised texts (one of which is given<br />

here as a reference).<br />

The strength of this book is<br />

the way it develops the<br />

fundamental ideas of<br />

atmospheric physics without<br />

introducing too much<br />

extraneous detail.<br />

The third chapter, on radiation, first<br />

derives basic equations of radiative<br />

transfer and spectroscopy before going<br />

on to describe the interaction of<br />

ultraviolet, visible and infrared radiation<br />

with the atmosphere. This leads on to a<br />

more detailed discussion of the<br />

greenhouse effect and atmospheric<br />

scattering. The mathematical<br />

development in this chapter is measured<br />

and carefully builds on basic principles; a<br />

careful balance must be struck between<br />

detail and clarity in this subject and<br />

Andrews is more successful than most<br />

authors in presenting this material in<br />

introductory texts.<br />

The two chapters on fluid mechanics<br />

are the best of the eight chapters in the<br />

book. They begin by deriving from first<br />

principles the basic equations of fluid<br />

dynamics, since this topic is often<br />

omitted from undergraduate physics<br />

courses. By building up carefully to<br />

quasi-geostrophic theory, gravity waves<br />

and Rossby waves the text emphasises<br />

the common principles underlying these<br />

concepts as well as opening up a broad<br />

field of atmospheric flows to quantitative<br />

study. This allows baroclimic and<br />

barotropic instability – topics often<br />

guarded by a palisade of differential<br />

equations in other texts – to be explained<br />

in a straightforward and logical way at<br />

the end of the chapter. An introduction<br />

to Ekman flow in the boundary layer is<br />

also included.<br />

The book concludes with three<br />

shorter chapters, on stratospheric<br />

chemistry, remote sounding and<br />

modelling. That on chemistry covers the<br />

basic concepts of atmospheric chemistry<br />

and provides an introduction to the<br />

Antarctic ozone hole. The remote<br />

sounding chapter has an impressive<br />

breadth for a book of this type, covering<br />

both passive and active (radar, lidar)<br />

ground-based methods as well as the<br />

more conventional space observations.<br />

The short final chapter gives a brief<br />

introduction to atmospheric modelling.<br />

The strength of this book is the way it<br />

develops the fundamental ideas of<br />

atmospheric physics without introducing<br />

too much extraneous detail. Its level is<br />

very well suited to its target readership<br />

and it is considerably more affordable<br />

than some of its competitors. Thus, I<br />

expect this book to become a standard<br />

text for many atmospheric physics<br />

courses in future years.<br />

<strong>Science</strong> for GCSE: Double Award, 2nd edition by Graham Hill<br />

Hodder and Stoughton. August 2001, £15.99, 328pp.<br />

ISBN 0-340-80044-5.<br />

Ifirst encountered this title, in the<br />

Spring, in its first edition, when asked<br />

to review it for the current ESTA exercise<br />

of evaluating the <strong>Earth</strong> science content in<br />

all the available school <strong>Science</strong> textbooks.<br />

This review relates to the <strong>Earth</strong> science<br />

content, with only passing reference to<br />

the other aspects of science.<br />

My first reaction, on hearing of the<br />

appearance of a second edition, was one<br />

of annoyance – in order to be fair to the<br />

publisher, I would have to look at it all<br />

over again! On second thoughts, perhaps<br />

the many errors in the first edition<br />

would have been corrected, so I turned<br />

to the task with expectancy. I soon<br />

realised that the wording and diagrams<br />

had been “tweaked” in many places, but<br />

that very few misunderstandings had<br />

been altered; new errors had been<br />

introduced, and various topics, such as<br />

transport and erosion had been deleted<br />

altogether. So, what is it like now?<br />

At first sight, the book is beautifully<br />

produced, and well laid out. It allows more<br />

space than the dreaded double page spread<br />

approach, and is full of good photographs,<br />

which must surely attract the average Y10<br />

and 11 student: indeed, it is aimed at those<br />

who are likely to be in the A* to C grade<br />

category at GCSE. It is divided into the<br />

traditional categories of Life processes and<br />

living things; Materials and their<br />

properties and Physical processes. The<br />

<strong>Earth</strong> <strong>Science</strong> content is distributed<br />

throughout the three sections, with most<br />

of it, of course, being in the Materials bit.<br />

Of the book’s 322 pages (excluding<br />

index), <strong>Earth</strong> <strong>Science</strong> in the widest sense<br />

occupies about 10%, which is par for the<br />

course, in comparison with other books<br />

surveyed. However, it also ranks too<br />

highly in the list for the number of errors<br />

per page, which is around 2, depending<br />

on how many times you count things like<br />

“liquid mantle” on the same page!<br />

So, why am I so disappointed with<br />

this book? I have to say that it gives the<br />

appearance that the <strong>Earth</strong> science has<br />

been grudgingly squeezed in, to satisfy<br />

the National Curriculum, and not<br />

because the author derives any pleasure<br />

from the subject. I assume that he is<br />

thoroughly familiar with his own<br />

specialism, but it is very obvious that he<br />

has not studied <strong>Earth</strong> science. To their<br />

shame, the publishers do not seem to<br />

have supported their author by asking a<br />

competent <strong>Earth</strong> scientist to check the<br />

manuscript before publication. In<br />

general, the approach does not fulfil the<br />

spirit of the National Curriculum,<br />

which is to get students to evaluate the<br />

evidence – as found in the rocks; for or<br />

against evolution; plate tectonics etc.<br />

Instead, there are brief statements of<br />

facts (or near-facts!) which students are<br />

expected to digest, with minimal effort<br />

at working things out for themselves. A<br />

classic example of the author’s own lack<br />

of application of the evidence is found in<br />

the perennial problem of the nature of<br />

the mantle. Throughout most of the<br />

book (e.g. pp 199 and 200), the mantle is<br />

stated as being liquid, yet on page 301 it<br />

is implied, in the briefest treatment of<br />

seismic waves that I have seen, that S<br />

waves do not penetrate the core, because<br />

it is liquid, yet they are able to pass<br />

through the mantle.<br />

It is all too easy to pick out the errors<br />

in any book and to share a giggle over<br />

coffee, but there are so many serious<br />

ones here, that I think another approach<br />

is needed. Examples include the<br />

statement that limestone is a good<br />

example of a mineral (p192); there is<br />

confusion between weathering and<br />

erosion (p 194), and no coverage of<br />

transport and erosion, per se at all;<br />

reference to plates as being “crustal”, and<br />

no mention of the lithosphere (although<br />

this is named in the National<br />

Curriculum). An appropriate<br />

photograph of a beautiful fossil fern<br />

(albeit referred to as being preserved in<br />

slate) appeared in the first edition. In the<br />

second edition however, it has been<br />

replaced with a superb fossil fish, with<br />

the caption, “This fossil of a prehistoric<br />

fish was left when the rest of it became<br />

crude oil”. The most inaccurate item in<br />

the whole book is the diagram on page<br />

196, purporting to show “the formation<br />

of igneous, sedimentary and<br />

metamorphic rocks”. Among several<br />

interesting phenomena, it depicts<br />

“igneous rock next to mantle, e.g.<br />

quartz, granite”, and it really must be<br />

redrawn before too many students see it.<br />

Overall, it is not even the gross errors,<br />

such as those identified above, so much<br />

as an almost indefinable air about the<br />

book, that one cannot always put a finger<br />

on, yet which confirms the impression<br />

that the author is uncomfortable when<br />

writing outside his own field.<br />

So what can ESTA members and other<br />

readers do to be helpful? I suggest that<br />

readers might like to consult whichever<br />

colleague is responsible for buying books<br />

for the school, and offer to look at any<br />

inspection copy which might be ordered,<br />

to see if you could help correct the main<br />

problems before any purchase is<br />

confirmed. Alternatively, if the school is<br />

already equipped with the first edition, at<br />

least students will hear of erosion and<br />

transportation! Perhaps you could then<br />

prepare an erratum page, to be inserted<br />

into each copy. With a group which has<br />

already learned its stuff, the book could be<br />

issued for the students to spot the errors<br />

themselves – an instructive exercise, when<br />

used with the right group!<br />

In common with other firms, the<br />

publishers have expressed their<br />

willingness to take part in the overall<br />

ESTA review exercise, and we believe<br />

that they have done so, partly so that they<br />

can attend to any errors and omissions<br />

before further editions appear. This<br />

independently solicited review will appear<br />

before the major project is completed,<br />

and may appear more embarrassing to the<br />

publisher, but I do hope that it will<br />

prompt them into taking the appropriate<br />

action in time for the next edition.<br />

This Dynamic <strong>Earth</strong>: the story of plate tectonics, by W J Kious and R I Tilling,<br />

USGS, Landscape format 27 x 21.5cm, 80pp, Obtainable from ESTA<br />

Promotions, price £7, post free. ISBN 0 16 048220 8.<br />

This Dynamic Planet - world map of volcanoes, earthquakes, impact craters<br />

and plate tectonics, USGS. Landscape format wall map, 140 x 104cm, also<br />

from ESTA price £6 post free.<br />

This is an unsolicited review,<br />

written because I think the<br />

materials are so good that<br />

everyone ought to have them!<br />

ESTA also needs to declare an<br />

interest in that the items are<br />

stocked by ESTA Promotions.<br />

The map has been available<br />

through ESTA for several years,<br />

and a much-used one still features<br />

on a display board in my old lab (I<br />

pop in now and then, just to<br />

check!). It shows all that the title<br />

says, and is excellent for patternseeking<br />

exercises, as well as for<br />

stimulating students’ interests in<br />

general. The topography of the<br />

ocean floors is shown faintly, but<br />

used in conjunction with the<br />

colourful map of the oceans floors<br />

by Marie Tharp (which also<br />

happens to be available from<br />

ESTA), one has all one needs for<br />

doing justice to plate tectonics and<br />

a lot more besides.<br />

I first became aware of the<br />

booklet, This Dynamic <strong>Earth</strong>,<br />

whilst enduring the heat of<br />

Australia at the International<br />

Geo<strong>Science</strong> Education Conference<br />

last year, it having been brought as a<br />

free gift by the US delegation. It is<br />

quite excellent, giving the story of<br />

plate tectonics in clear English, with<br />

well chosen photographs, and with<br />

simple, bold diagrams. It also<br />

includes some of the human stories,<br />

such as how Wegener died in<br />

Greenland in 1930 and how Harry<br />

Hess managed to combine hunting<br />

enemy submarines during the War,<br />

with thinking about the geology of<br />

the ocean floors. It is not over<br />

(overly?!) American, and Vine and<br />

Matthews’ work is explained very<br />

clearly, among others.<br />

So far, I have only been made<br />

aware of one error, and that is a<br />

simple transposition of a caption<br />

on page 18, spotted by a historian!<br />

Since my discovery of the<br />

booklet, ESTA has ordered copies<br />

from the USGS and the <strong>Earth</strong><br />

<strong>Science</strong> Education team has<br />

added the items to the kit of<br />

“samples” taken round to INSET<br />

courses. Both the booklet and the<br />

map have proved extremely<br />

popular among <strong>Science</strong> teachers,<br />

who see them as a way of<br />

enlivening their own knowledge<br />

of the subject and of capturing<br />

their students’ interest. I find that<br />

I am selling either one or the<br />

other, and quite often both, at<br />

most of the meetings in recent<br />

months, and we have had to<br />

reorder twice already.<br />

If I made any personal money<br />

out of promoting something like<br />

this, I could rightly be castigated<br />

(I did look it up!). However, the<br />

only people to benefit will be<br />

YOU; your students and<br />

colleagues; ESTA (not by much!);<br />

and, of course the USGS and their<br />

carriers! Excellent value for money<br />

- buy one of each for Christmas!<br />

Cash for Research: The P. T. Carr Award<br />

In 1996 the late Peter Towsley Carr left a bequest of £3,000 to create an award to be<br />

administered by the <strong>Earth</strong> <strong>Science</strong> Teachers <strong>Association</strong> (ESTA). The purpose was to fund<br />

geological research by practising schoolteachers.<br />

Peter Carr was born in 1925, and<br />

began his working career at High<br />

Duty Alloys in Slough. While<br />

working he studied part-time at Chelsea<br />

Polytechnic for a geology degree (with<br />

subsidiary maths) which he obtained<br />

around 1950.<br />

He joined the staff of what eventually<br />

became Herschel School, Slough, a technical<br />

high school, and remained there for<br />

the rest of his career. Initially he taught<br />

both subjects to A-level, but with only a<br />

small number of A-level geology students<br />

and an increasing shortage of qualified<br />

maths teachers, the school<br />

eventually decided that he was better (?)<br />

employed as a full-time mathematician.<br />

His brother Alan thinks he understood<br />

their logic in this, even if he was reluctant<br />

to agree with it.<br />

Peter himself struggled to do a research<br />

project on the Lizard in Cornwall, and was<br />

anxious that others might be funded in<br />

such a project to enable a successful outcome<br />

without undue financial difficulties.<br />

He died in February 1996.<br />

Aim of the award<br />

The aim of the award is to help to fund a<br />

practising schoolteacher wishing to undertake<br />

geological research, or to enable such a<br />

person to complete research already begun.<br />

‘Geological research’ is here interpreted<br />

in a wide sense, to include<br />

research into:<br />

● an aspect of the geology of an area,<br />

particularly one local to the teacher’s<br />

school<br />

● geological and <strong>Earth</strong> science education<br />

at all levels<br />

● the role of conservation in geology and<br />

<strong>Earth</strong> science<br />

● improving the use of geological collections<br />

in education<br />

● improving the public understanding of<br />

geology and <strong>Earth</strong> science<br />

● the use of Information Technology in<br />

any of the above<br />

Finance<br />

The legacy of £3000 has been invested to<br />

produce an income. This income will be<br />

used to fund an award every THREE<br />

years. It is anticipated that the award will<br />

usually be of the order of £500, but this<br />

cannot be guaranteed.<br />

Procedure for making the award<br />

ESTA Council will delegate responsibility<br />

for administering the award to a sub-committee<br />

which must include at least one<br />

from the Chairman, Secretary or Treasurer<br />

of the <strong>Association</strong>.<br />

Notice of the award will be publicised<br />

by the sub-committee in Teaching <strong>Earth</strong><br />

<strong>Science</strong>s (or its successor journals) and<br />

by other appropriate methods as decided<br />

by the sub-committee to try to maximise<br />

the number of potential applicants. A<br />

deadline for the receipt of applications<br />

will be set.<br />

The sub-committee, with the approval<br />

of ESTA Council, may suggest a specific<br />

area of geological research for which the<br />

award might be made on a particular occasion.<br />

This discretion is intended to allow<br />

the sub-committee to encourage research<br />

that may be of particular value to geological<br />

education at a given time.<br />

Applicants will be required to supply<br />

sufficient personal details of their qualifications<br />

and experience, including previous<br />

research if any, at least two referees who<br />

can attest to their suitability to undertake<br />

research and receive the award, and an<br />

outline of the research proposal in such<br />

format as the sub-committee may from<br />

time to time determine. Applicants will<br />

also be required to outline how the award<br />

will be used to enable the research to proceed.<br />

The sub-committee will scrutinise<br />

and evaluate the applications, and may ask<br />

to interview applicants if it is felt to be necessary.<br />

The sub-committee’s decision will<br />

be ratified by Council, and that decision<br />

will then be final.<br />

Wherever possible, the selection procedure<br />

will be timed to enable an announcement<br />

and presentation of the award at the<br />

Annual Conference of the <strong>Association</strong>,<br />

usually held in September.<br />

No serving member of ESTA Council<br />

will be eligible for the award, although<br />

an award-holder may later be elected or<br />

co-opted to Council without prejudice.<br />

Expectations of the award-holder<br />

The award-holder will be expected to<br />

1. undertake and complete the planned<br />

research project within an agreed<br />

timescale, in general before the next<br />

award is due to be made (normally<br />

three years).<br />

2. keep the sub-committee informed of<br />

the progress of the research by means<br />

of a brief annual report in a form specified<br />

by the sub-committee.<br />

3. inform the sub-committee without delay<br />

if a change in circumstances may lead to<br />

a delay in completing the research project<br />

within the agreed timescale, or to<br />

abandonment of the project.<br />

4. return such part of the monies awarded<br />

as the sub-committee may determine to<br />

be reasonable should he or she fail to<br />

complete the research project within the<br />

agreed timescale, or within such extended<br />

timescale as the sub-committee may<br />

grant at their complete discretion.<br />

5. publish his or her work as a paper in<br />

Teaching <strong>Earth</strong> <strong>Science</strong>s, and present his<br />

or her work to members as a talk at an<br />

Annual Conference of the <strong>Association</strong>.<br />

The closing date for the 2002 Award is July 31st 2002.<br />

Best Practice Research<br />

Scholarships<br />

Nearly two years ago the UK<br />

government announced a budget<br />

of £6 million over 2 years for<br />

serving teachers to carry out smallscale<br />

classroom-focused research<br />

which would be immediately<br />

relevant to their own situations.<br />

Bids in certain fields were invited,<br />

although these are sufficiently<br />

wide to encompass almost any<br />

school-based research. Teachers<br />

were invited to link up with<br />

Higher Education Mentors and<br />

submit bids for sums of about<br />

£2,500. Teachers across the<br />

country are now carrying out their<br />

research, some working alone<br />

(well, you know what I mean!) but<br />

most are in small teams or larger<br />

Press Release:<br />

“Material World” –<br />

Hanson’s education project for schools is launched on 1 October 2001<br />

“Material World is designed to introduce Key Stage 2 children (primary school children)<br />

to the processes of quarrying and brickmaking. The Material World project is made up<br />

of two essential resources for schools. Firstly, a visit to a Hanson quarry or brickworks,<br />

and secondly, the accompanying teachers’ resource pack. The site visit and the teachers’<br />

pack are designed to provide an enjoyable educational experience that relates closely to<br />

the National Curriculum.<br />

During a school visit to a Hanson site, teachers and pupils will learn about the history<br />

of quarrying and brickmaking in their area. They will see how stone or clay is collected<br />

and then processed. The site visits and resource pack show how these processes relate to<br />

the National Curriculum, with particular emphasis on materials and their properties,<br />

environmental issues and environmental change.<br />

Over 130 Hanson quarries and brickworks all over the UK are taking part in the<br />

project from September 2001, with school visits planned throughout the autumn<br />

months.<br />

The teachers’ resource pack has been written by Mike Hirst PGCE, an experienced<br />

teacher, author and editor. It has been checked by Hanson’s educational advisors. The<br />

Material World project took two years to develop, and - as well as a range of pupil<br />

activity sheets - includes 4 posters, a rock and a brick box, and fun elements including<br />

stickers, tree tags and quiz cards.<br />

Hanson are making no charge for site visits or the accompanying Material World<br />

resources. Hanson takes issues of safety at its sites extremely seriously. All site tours are<br />

thoroughly assessed for potential risks in accordance with company and Government<br />

regulations.<br />

Teachers can find out more information about Material World and how to contact<br />

their nearest Hanson brickworks or quarry by visiting:<br />

www.hansonplc.com/education<br />

consortia. The scheme is managed<br />

by Nord Anglia on behalf of<br />

DFES. It is anticipated that<br />

teachers will be invited to make<br />

bids for the next round of<br />

allocations (ie starting in<br />

September 2002) in January and<br />

February 2002. If any TES reader<br />

has an interest in drawing up a<br />

bid, or in being part of a larger<br />

research group, they should get<br />

further details from the Best<br />

Practice website at<br />

www.dfee.gov.uk/bprs. They could<br />

also contact an <strong>Earth</strong> science<br />

educationalist in the education<br />

department of a higher education<br />

institution. The TES Editor<br />

(Roger Trend) coordinates all Best<br />

Practice scholarships at the<br />

University of Exeter (ie not just<br />

the <strong>Earth</strong> science ones) and he<br />

would welcome enquiries.<br />

a new pack on quarrying and<br />

brick-making, intended mainly for<br />

use at Key Stage 2 but with some<br />

potential for use at Key Stage 3. At<br />

the core of the project is a large<br />

ring-bound Teacher Resource Pack<br />

which is to be used in conjunction<br />

with a site visit (quarry or<br />

brickworks). This file contains<br />

detailed teacher notes, pupil<br />

resource sheets and pupil task<br />

sheets. Four folded A2 coloured<br />

posters are also included and at<br />

each of Hanson’s UK sites there is<br />

a Rock Box or a Brick Box which<br />

can be loaned to schools who are<br />

arranging a site visit. The materials<br />

are very attractive, very<br />

comprehensive and well-presented<br />

as robust sheets. All photocopiable<br />

sheets are laminated.<br />

The teacher file is divided into<br />

8 sections, each with teacher<br />

information and pupil learning<br />

activities. The Introduction sets<br />

RAISING STANDARDS IN EARTH SCIENCE TEACHING (The Joint <strong>Earth</strong> <strong>Science</strong> Education Initiative)<br />

In the run up to taking the ESTA chair in 2000, perhaps somewhat naively,<br />

I suggested that ESTA’s vision and priorities should be re-orientated,<br />

to address more fully the needs of the c10 million children in UK schools<br />

being taught science. The enormity of the task was awe-inspiring. The<br />

odds were clearly against success: not only were the resources meagre<br />

in the extreme, by all accounts there was an ‘entrenched folklore’ of<br />

antagonism towards <strong>Earth</strong> sciences on the part of ‘mainstream’ science<br />

teachers, having to shoe horn this alien science into an overcrowded<br />

science curriculum.<br />

At the same time, the initial findings of research (ongoing) by Chris<br />

King and Alastair Fleming of the <strong>Earth</strong> <strong>Science</strong> Education Unit (ESEU)<br />

at Keele University were disturbing. They pointed not only to<br />

widespread poor standards in <strong>Earth</strong> science <strong>teaching</strong> in schools by<br />

non-specialists, but also to howlers in textbooks and, even more<br />

worrying, in examination board questions, which would not be out of<br />

place in the pages of Just William (King 2001).<br />

To our pleasant surprise and great relief, preliminary soundings of<br />

the other science subject <strong>teaching</strong> associations were encouraging. Far<br />

from objections and turf wars, talks began in earnest in late 2000,<br />

embracing the Royal Society of Chemistry, the Institute of Physics, the<br />

Institute of Biology and ESTA under the good offices of the Royal<br />

Society. The Geological Society is also represented on the steering<br />

group. The parties involved were not merely amicable but enthusiastic<br />

in their willingness to confront the issues. Working together, the Joint<br />

<strong>Earth</strong> <strong>Science</strong> Education Initiative (JESEI) was established. With<br />

generous core funding (and most welcome direct involvement) from the<br />

United Kingdom Offshore Operators <strong>Association</strong> (UKOOA) and<br />

contributions of finance or expertise, from the subject <strong>teaching</strong><br />

organisations concerned, material is now being prepared to support and<br />

improve standards of <strong>Earth</strong> science delivery by chemistry, physics and<br />

biology teachers respectively. The aim is not necessarily to reinvent<br />

wheels, but to point practitioners to existing high quality material.<br />

Initial topics under way or being considered include: volcanoes<br />

(origins and impacts); copper mineralisation; limestone (the World’s<br />

most useful rock); characteristics of sandstones; seismic waves/ <strong>Earth</strong><br />

structure; and fossils. Again, thanks to UKOOA sponsorship, some of<br />

these will receive a first airing at the <strong>Association</strong> for <strong>Science</strong> Education<br />

annual conference in January 2002 in Liverpool. These and other<br />

dedicated <strong>Earth</strong> science workshops are being widely promoted at this<br />

annual event which usually attracts 4-5,000 participants.<br />

The current JESEI programme focuses upon secondary (Key Stages<br />

3 and 4) science; the ultimate intention is to extend the work to<br />

primary (Key Stages 1 and 2) and to geography.<br />

Ian Thomas<br />

the scene, not only by giving<br />

mildly promotional information<br />

about Hanson’s global operations<br />

in quarrying and brickmaking but<br />

also by pointing teachers to the<br />

relevant National Curriculum<br />

statements in science, geography,<br />

maths and English.<br />

Section 1 of the teachers file<br />

(“Magnificent Materials”) focuses<br />

on rocks and minerals, especially<br />

in relation to a site visit. It is<br />

significant that “minerals” in the<br />

teachers’ notes are described as<br />

“ingredients from which rocks are<br />

made”, with no reference to the<br />

concept of bulk construction<br />

minerals. Surely this is an<br />

opportunity to clarify the<br />

difference in the two uses of the<br />

“mineral” label, at least for the<br />

teachers. Section 2 (“Researching<br />

Rocks”) contains a good selection<br />

of <strong>teaching</strong> ideas, although I<br />

always get suspicious when I read<br />

something like “geologists also<br />

group rocks according to their<br />

hardness” (page 2:2) because I<br />

know what often follows! I am<br />

afraid it is true this time as well.<br />

Later in Section 2 we find a pupil<br />

resource sheet (“Rock Fact Chart”)<br />

which comprises 15 rock types<br />

(basalt and granite, through shelly<br />

limestone and coal to slate and<br />

schist) which are summarised<br />

under 5 variables: Is it found in<br />

the UK? (all are ticked, of course);<br />

type of rock (igneous, sedimentary,<br />

metamorphic); can you scratch it<br />

with your fingernail? (the concept<br />

of hardenss applied to a rock: no<br />

comment!); can you scratch it<br />

with a steel nail? (ditto: no<br />

comment again, although<br />

conglomerate is ticked and granite<br />

is not ticked.... interesting); what<br />

colour is it? It is a pity that such<br />

woolly material is allowed to find<br />

its way into such a good resource.<br />

I wonder how it happened?<br />

Section 3 (“Bricks for Building”)<br />

offers some excellent <strong>teaching</strong> ideas<br />

about brick-making, heating<br />

materials and developing numeracy<br />

skills (although goggles are not<br />

mentioned where they should be).<br />

Sections 4 and 5 look at “Quarries<br />

in Action” and “Quarry Control”<br />

respectively and are strongly<br />

orientated towards a site visit.<br />

Section 6 continues with the strong<br />

environmental emphasis started in<br />

Section 5 and deals with the issues<br />

associated with quarry extension. A<br />

lively and imaginative role play is<br />

given: Miss Busy, Mr Strong, Mr<br />

Green etc, each with a brief role<br />

and each putting their views on the<br />

proposal to extend Rocky Quarry.<br />

Unlike other similar role-play<br />

situations, however, the “correct”<br />

answer is provided with the<br />

resources: “The local council<br />

decide to allow the extension to<br />

Rocky Quarry”! This predetermined<br />

outcome is given on<br />

the pupil resource sheet (p. 6:8), so<br />

perhaps the bright spark in Year 6<br />

who spots it right at the start of the<br />

debate might suggest that they call<br />

the whole thing off and either go<br />

home to watch tele or organise a<br />

militant demonstration! Clearly<br />

rational debate is merely a charade!<br />

The final two sections in the<br />

Teacher Resource Pack deal at<br />

greater length with environmental<br />

management.<br />

This is a good resource which,<br />

in the hands of a teacher who can<br />

not only exploit its strengths but<br />

also avoid its potential weaknesses,<br />

will enhance children’s<br />

understanding of the science and<br />

geography of quarrying and brickmaking<br />

in the UK.<br />

Jurassic Coast Makes a Splash on the World Wide Web<br />

A new and exciting website about<br />

the internationally important<br />

geology and fossils of the Dorset<br />

and East Devon coast is now<br />

accessible on the World Wide Web.<br />

The web site aims to promote<br />

new forms of special interest and<br />

out of season tourism through<br />

sections exploring interests such as<br />

fossil collecting, Portland Stone,<br />

dinosaur footprints, geology in the<br />

landscape and how the use of local<br />

stone has created the different<br />

character of the coastal towns and<br />

villages. Much of the content is<br />

based on the current nomination<br />

of this coastline for World<br />

Heritage Site status centred on the<br />

case that has been made to<br />

UNESCO. A further section<br />

provides educational resources for<br />

schools and colleges, based on the<br />

difficult issues of coast protection.<br />

‘We hope that the site will help<br />

people who already come to the coast to<br />

enjoy it further. However, many of these<br />

interests, by their very nature, are best<br />

explored outside of the main season and<br />

therefore we hope to promote visits in<br />

the spring, autumn and even winter.’<br />

Dorset and Devon County<br />

Councils and the Dorset Coast<br />

Forum have developed the web<br />

site. The funding partners reflect<br />

the multiple aims of the site: the<br />

Countryside Agency wish to<br />

promote awareness of the coast,<br />

the South West Grid for Learning<br />

are developing local educational<br />

resources and SCOPAC, (the<br />

Standing Conference On<br />

Problems Associated with the<br />

Coast) wish to explain the difficult<br />

issues that coastal engineers face<br />

when seeking to manage the coast.<br />

The Okehampton based company<br />

‘Image Makers’ has provided the<br />

technical expertise.<br />

Richard Edmonds said:<br />

‘In order to appreciate the problems facing<br />

the coastal engineers it is important to<br />

understand the geology and coastal<br />

processes acting along this coast. That is<br />

why we are developing a series of animations<br />

to illustrate the last 125 thousand<br />

years of history along this coast, including<br />

the latest theories on the formation of<br />

Chesil Beach.’<br />

‘And this is just the start as the site<br />

offers the potential to link with other<br />

internationally important fossil and<br />

geology sites around the world in order<br />

to promote a network of the top<br />

geological sites, again promoting special<br />

interest tourism.’<br />

The web site can be accessed at:<br />

www.jurassiccoast.com<br />

The World Heritage Site<br />

nomination has been put<br />

together by Dorset and Devon<br />

County Councils and the Dorset<br />

Coast Forum.<br />

An Important New British Geological Survey<br />

Project to boost school <strong>Earth</strong> science education<br />

Are you frustrated by a lack of good, imaginative<br />

<strong>teaching</strong> resources? Then you might like what the<br />

British Geological Survey is planning!<br />

We have just launched a new project - a<br />

programme of market research aimed at UK<br />

teachers of <strong>Earth</strong> <strong>Science</strong>, Geography and<br />

Geology to find out what they require in the way<br />

of <strong>teaching</strong> resources and materials; to identify<br />

any gaps in the spectrum of available <strong>teaching</strong><br />

resources for those subjects, and to attempt to<br />

discover what those teachers would ideally like in<br />

terms of <strong>teaching</strong> resources.<br />

The purpose of this market research will be<br />

to determine if the BGS can produce <strong>teaching</strong><br />

materials and resources to meet teachers’<br />

requirements. We are not only considering<br />

books as <strong>teaching</strong> resources - we shall be<br />

looking at resources across all media; printed<br />

text, web pages and downloadable information,<br />

CD-ROMs, slide sets and other photographic<br />

resources, sets of rock and mineral samples...let<br />

us know your needs! If new BGS products and<br />

publications prove to be feasible, they will be<br />

developed in tandem with those teachers<br />

willing to help the BGS with this aspect of the<br />

market research.<br />

The market research programme will initially<br />

take the form of a questionnaire, and will be<br />

backed up by face-to-face meetings with teachers,<br />

to discuss specific resource needs in detail. We are<br />

keen to get in touch with as many teachers as<br />

possible, and we would like as wide a range of<br />

input as we can gather.<br />

The questionnaire may be found on the BGS<br />

website: www.bgs.ac.uk/education/home.html<br />

This will take you to the BGS Education<br />

home page; there is a link on that page called<br />

‘Teachers’ Questionnaire’, where the<br />

questionnaire can either be downloaded or<br />

completed online. If you do download the<br />

questionnaire, please return it to:<br />
