    In this activity, students construct models that resemble rain falling on a hillside to observe factors affecting soil erosion and ground stability.

    By the end of this activity, students should be able to:

    • explain that erosion is the wearing away of soil by water
    • demonstrate that steepness of land affects rate of water flow and potential for erosion
    • demonstrate two ways in which vegetation prevents or lessens erosion.
