Next, the students observed and described the flow of water through a stream model. They made changes to their stream models, such as building damns, and observed how those changes effect the flow of water on Earth. The students built "Tiny Towns" and observed what would happen to the "citizens" if and when a flood occurred. Throughout these explorations the students were able to describe the movements of earth materials in their models as erosion and the landing places of earth materials as deposition. They experienced in a concrete, hands-on way why scientists use models to help them learn about real things.
The students built stream models and observed how water moves Earth materials.
