Giving kids a hands-on opportunity to see energy in action, these 25 projects are an exciting introduction to the ways this hot topic affects both world politics and everyday lives. Packed with information about what energy really is, where it comes from, and its alternative sources, the projects range from a steam-powered boat and a solar-powered water heater to an electric burglar alarm and a geothermal geyser. The tough topics of energy shortages are covered with enthusiasm in a lively discussion so kids can make educated, positive changes for their future.
