Earth Science
Water
Groundwater Model
A graphic simulation of the principles
of groundwater movement and contamination.
Using this durable acrylic
model, students will learn about the
sources of groundwater, its storage
and flow beneath the earth’s surface,
and how this resource impacts life
at the earth’s surface. Dyes are used
as simulated contaminants to reveal
how groundwater can become
polluted and affect drinking water
supplies. By demonstrating concepts, students
learn about groundwater’s critical role in the hydrological cycle. Includes
easy-to-use student and teacher guides. Size: 20" L x 5" W x 12½" H. Grades 7—12.

Environmental Monitoring Test Kit
This combination chemical test kit allows the user to
perform analysis of the six most important parameters
to be monitored in the environment: acidity,
alkalinity, carbon dioxide, dissolved oxygen, hardness,
and pH. Contains all the accessories and reagents to
perform over 100 tests each of the parameter. For pH
measurements, the kit offers the popular pH electronic
tester, pHep ® . This small and easy-to-use pH meter will
provide more accurate and reliable pH readings than
conventional litmus paper and has the added benefit
of introducing students to the use of a pH meter. The
kit comes complete with a step-by-step instruction
manual and a hard carrying case which makes it easy
to perform tests in the field. Case dimensions: 17 5 ⁄16" x
13" x 4". Grade 5 and up. Sh. wt. 2.33 kgs.

Exploring
Groundwater Pollution
Construct a mini-groundwater
simulation model showing the movement
of a simulated, coloured pollutant.
Determine under what conditions
contamination occurs from a variety of
sources such as spills, farms, and buried
tanks and how polluted groundwater
eventually reaches the drinking water
supply. In the process, students learn
about the water cycle, water quality,
ppm and ppb pollutant contamination,
porosity of soils, and other related concepts.
Enough materials for a class of 40
students. Grades 5—12.

Water Quality
Educator & Monitoring
Outfit
The tools you need to start or
enhance an existing water quality
monitoring program. Kit includes
The Monitor’s Handbook, test kits,
and CD-ROM. The Water Quality
Monitoring Outfit includes complete
tests for seven critical water
quality test factors (pH, Nitrate-
Nitrogen, Phosphate, dissolved
Oxygen, total alkalinity, turbidity,
and temperature) and lesson plans
for grades 5—8 and 9—12. CD-
ROM is compatible with both PCs
and MACs and is run through Quick Time ® Media Player. Interactive media provides stepby-step
instructions for water quality test procedures using the test kits and sampling
equipment included. Grade 5 and up. Sh. wt. 13.19 lbs.

WaterWorks 9-Way
Classroom Test Kit
With enough materials for 30
students, this classroom kit
includes test strips for testing nine
different parameters including free
chlorine, total chlorine, pH, total alkalinity,
iron, copper, total hardness, nitrite
nitrogen, and nitrate nitrogen. Safe nonhazardous
test strips feature quick, accurate,
and inexpensive water testing with
easy-to-follow dip and read instructions.
Contents: 60 tests for each parameter,
activity booklet, pipettes, and vials.
SB31266M — $114.85
Water Quality Test Kit
An ideal way to monitor the general quality of most
important chemical parameters in water: alkalinity,
chloride, hardness, iron, pH, and sulfite. Kit contains
all the reagents needed to perform over 100 tests for
each parameter. pH measurements are performed
with the electronic pH tester, pHep ® , which guarantees
more accurate and repeatable readings than litmus
paper. The chemical reagents to perform each test are
provided in numerically coded bottles and are easy to
identify. The kit is supplied with a convenient hard carrying
case which makes it easy to carry the reagents
in the field and keep them neat and organized. All
the titration reagents are prestandardized and do not
require chemical handling to perform the analysis. This
kit offers all the necessary equipment for accurate and
reliable water quality testing. Case dimensions: 17 5 ⁄16" x 13" x 4". Grade 5 and up. Sh. wt.
2.21 kgs.
SB35045M — $296.05
Coliform Test Kit
Specifically designed for the teacher
who wants to dramatically and vividly
show the classroom a pollutant
in water. This kit permits students to
determine the presence or absence
of Escherichia coli (indicative of animal
waste) in a water supply. By seeing
a dramatic colour change that
occurs in a lactose broth, students
can determine if E. coli are present.

Bacterial
Contamination of
Water Lab
Investigation
Investigate the environmental
issues caused
by waterborne bacteria.
Your class will test a variety
of water samples
they collect for possible
contamination by coliform and other bacterial strains.
They’ll also perform a total plate count of bacteria and
observe bacterial smears under a microscope. For 40
students. Grades 9—12. Sh. wt. 4.50 lbs.
SB47601M — $89.20
Do Landfills Really Work?
Lab Investigation
Build your own mini-landfill, investigating
the biodegradability of various wastes
in a sanitary vs. an open configuration.
Using the results, the class determines
the advantages and disadvantages of
these two standard types of landfills and
explores their long-term effects on the
environment. Additionally, they explore
alternatives to landfills, such as composting
and recycling. Enough materials for 40
students. Grades 7-10. Sh. wt. 10 lbs.
