Electricity From Water, Wind & Sunlight (grades 4-6) Students' and teachers' interests in renewable energy sources provide a stimulus for activities that clarify the nature of electricity and the process of generating it. Students build their own galvanometers to detect small electric currents. Working in groups and using patterns provided in the booklet, they construct wind turbines (from construction paper) or water turbines (from milk cartons), connect them to a generator, and detect the electricity produced. Experiments with a photovoltaic cell are also suggested. This hands-on unit is an excellent complement to our Generating Electricity and Energy Transformations titles. The thoughtful Teacher's Guide gives a complete overview of the activities and makes suggestions for introducing different subjects into the curriculum. Kits with both print materials and hard-to-find lab activity supplies are available.  Student booklet: 16 pp., full color.

"The Los Angeles Department of Water and Power has found that Enterprise for Education's materials have been among our most well received programs for teachers, especially related to green power, electric vehicles, and electric safety. I encourage other utilities to consider using these fine materials with their teachers in their respective service areas." -- Walter Zeisl, Manager, Public Affairs and Education, Los Angeles Dept. of Water and Power
