What causes the Earth to change? Some of the ways that the Earth is constantly changing is by weathering and erosion. Weathering is the breaking down of rocks and other materials. Erosion is the carrying away of these broken down particles by running water, glaciers, wind and waves. To demonstrate the affects that wind and water have on the land, the 4th graders conducted an experiment.
Representing their islands was a large mound of soil. Students were given small hand held fans to simulated the blowing wind. Then they were given a cup of water to simulated a flood or rainfall, as some sprinkled the water over the land. What were the results? Check out what happened by watching the video below.
