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.
