Preventing Erosion
Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land
Suggested ages 7–8
Learning journey
Your child is learning about Earth's structure — exploring different types of rocks and soil, understanding where water is found on our planet, and discovering how land shapes change over time.
Evidence of understanding
- Describe how wind and water can change the shape of land (erosion)
- Compare at least two design solutions for reducing erosion (e.g. retaining walls, plants, windbreaks)
- Evaluate which solution works best based on evidence from tests or observations
Assessment prompt
If Preventing Erosion sees a sandcastle being washed away by waves, can they think of ways to protect it — like building a wall or planting grass to hold the sand?
