Electricity is so much more than just plugging a lamp into the wall to make it light. Its power is found in batteries—in a flashlight and in a car—as well as in the world around us in the forms of static electricity and lightning! In this volume, readers learn the many aspects of electricity, including complementary information about conductors and insulators, circuits, and voltage. Simple, step-by-step instructions guide readers through creating a robot head, a circuit, a simple switch, and more.
