SURFACE CHANGES<br />
Lesson 6<br />
Lesson plan<br />
Introduction:<br />
1. As a class, recall what erosion is (the taking away/movement of broken-down s<strong>and</strong> <strong>and</strong> rock by<br />
wind, water <strong>and</strong> glaciers). How might humans be another force of erosion? In pairs, students<br />
brainstorm examples of human activities they think may contribute to erosion, <strong>and</strong> compile words<br />
<strong>and</strong> pictures using a digital application such as Popplet. QP<br />
Development:<br />
2. Students investigate the ways that humans contribute to erosion by conducting internet research.<br />
Students can begin their search at . PC<br />
3. In pairs, students create a digital presentation or slide show using an application such as<br />
PowerPoint ® or Keynote ® . Students should include a title/introduction page, a definition of<br />
erosion, a photograph demonstrating four types of human erosion as mentioned in the website<br />
(deforestation, mining, development <strong>and</strong> construction, <strong>and</strong> agriculture), <strong>and</strong> a sentence explaining<br />
how humans move or take away the s<strong>and</strong> <strong>and</strong> broken-down rocks in each photograph. PA C<br />
Differentiation<br />
• Less capable students can use one website <strong>and</strong> write keywords <strong>and</strong> less complicated sentences<br />
instead.<br />
• More capable students can conduct further research <strong>and</strong> use another website to gain more indepth<br />
information.<br />
4. As a class, view <strong>and</strong> discuss the video Hillside erosion: how to stop it at , which shows how a Natural Resources Management board in Willunga Hills,<br />
South Australia is helping reduce the impact of erosion caused by poor farming practices, by<br />
encouraging farmers to look after their l<strong>and</strong> <strong>and</strong> revegetate areas near creeks. How did humans<br />
cause erosion in Willunga Hills? How are they trying to help stop erosion? PC<br />
5. In small groups, students locate <strong>and</strong> document a local example of how humans have caused<br />
erosion but also how humans can help reduce erosion. Students create a short documentary similar<br />
to the Hillside erosion video, incorporating a question-<strong>and</strong>-answer format. An application such as<br />
iMovie ® can be used. QP PA PC C<br />
Reflection:<br />
6. Students play their short documentary to the class, upload it to a school website or email it to<br />
classmates or family. As a class, discuss the different examples shown. Write a list of the different<br />
areas <strong>and</strong> the ways that humans have impacted each, <strong>and</strong> how people can help prevent future<br />
erosion. C<br />
