Why Do We Have Dams?

This activity examines many of the reasons why it is important to construct large dams, specifically, the three major dams across the Gunnison River leading into Black Canyon (Colorado). The importance of the dams for irrigation, electrical supply and recreation throughout history is explored. Students will learn about the different types of dam constructions, with pros and cons for each. There is also a component that allows the user to conduct a simulation of dam strength by changing load and stress characteristics on a virtual dam. Finally, students learn about dams near their school and home and of their environmental impact, as well as considering the importance of dam construction to human beings.
