Students use a two-liter bottle, dowel rod and index cards to design and construct a water wheel. They then calculate the power created and measure the work done by the water wheel in Watts and Joules.

Chapter 19 of a report on the energy industry in Texas. It looks at hydroelectric power, its history, and how it is used. Hydropower in Texas is described, its economic impact, how it is produced and its availability. The costs and...

It's hard to believe that the same water that you use every day to quench your thirst, cook with, bathe in, swim in, and wash your clothes and dishes, is capable of another trick-it can make electricity. Electricity can be generated...

Of the renewable energy sources that generate electricity, hydropower is the most often used. Learn other interesting facts about hydropower as the pictorial illustrations bring the information to life.

What is good, bad, and next for large dams in the United States? Examine biological and ecological, sociological and cultural, legal and political, and economic effects of building a dam.

Article describes the raging controversy over the gigantic dam on the "Fabled Yangzi River." Decide for yourself; will this help China enough to warrant the environmental destruction?

Students are introduced to the concept of a dam and its potential benefits, which include water supply, electricity generation, flood control, recreation and irrigation. This lesson begins an ongoing classroom scenario in which student...

Students are introduced to the basic biology behind Pacific salmon migration and the many engineered Columbia River dam structures that aid in their passage through the river's hydroelectric dams. Students apply what they learn about the...
