Designing Eco-Friendly Dams

Summary

People build dams for many reasons. Many dams are built to produce electricity or to control flooding. No matter what the use, dams function by blocking the flow of water in a river.

In this activity, you will build a model dam and experiment with water flow and depth to observe the effect on upstream and downstream land areas. From your observations, you will infer how changing water flow may affect the organisms that live in the area.
