Science at key stage 3 (Year 8)
Unit 8G: Rocks and weathering
Section 4: Checking progress
|
|
Objectives |
| Children should learn: |
- to relate a landscape to a process of weathering
|
Activities |
|
Outcomes |
|
Children: |
- Show pupils photographs of natural scree slopes,
eg Wast Water in the Lake District, and ask them to suggest how rock ended up as fragments in a pile at the bottom of the cliff and what the scree slope tells us about past conditions. Ask pupils what characteristics would lead to rocks being weathered easily.
|
|
- identify conditions under which rocks fragment
- explain the formation of the scree slope in terms of these conditions
|
|
Points to note |
- Pupils would not be expected to recall terms such as
'scree slope'.
- Extension: to test their ideas, pupils could investigate rock resistance by shaking several small specimens of different rock types in a plastic container and recording changes of size after different time intervals.
