Hydroelectricity is a clean and renewable source of energy that supplies electricity to many parts of the United States. Assembling this kit gives your students an opportunity to produce a working model of a hydroelectric generator that will light an LED. The design element of this activity challenges your students to produce turbine blades that provide the most efficient use of the moving water. Measure output with a multimeter. Running water is needed; some tools are needed for drilling. Red acrylic base is included.
