Changing the Shape of Land Activity for Kids
- 1Stack of books
- 1Watering can with water
- 2Cake pans
- 2Bread pans
- 1Pack of soil
- 8Plastic forks
- 1Fill two cake pans with an equal amount of soil and carefully pat it down a little.
- 2Lean the cake pan on a pile of books and lean the other side in the bread pan.
- 3In one of them, stick forks into the soil, this will act like trees.
- 4Slowly pour water onto the soil on one side of the bread pan.
- 5Watch it flow down into the cake pan.
- 6Observe how much soil was eroded away.
- 7You can test other ways to slow down or stop erosion using this model.
How It Works
Erosion is when tiny pieces of the Earth’s surface are moved from one place to another. This is usually caused by moving water or wind. In our model we used flowing water to move soil. Plants are a great way to slow down or stop erosion and the forks we stuck into the soil acted like the roots of a plant to help hold the soil in place.
