Children will be "shocked" to learn that with just a few wires, batteries, bulbs, and buzzers they can unlock the mysteries and magic of electricity! These simple and safe experiments will prove enlightening on everything from electrons to circuits to wattage. Bend paper with a comb that's "charged up" with static electricity. Find out what lemons, potatoes, and coins have to do with electricity by using them to discover how a battery works, and then get right down to the "nuts and volts" of the matter by making one of your own. Also see why "opposites attract," construct a circuit board, send a coded message with a buzzer; and lots more. By the time children have tried out all these amazing experiments, they'll realize for the first time why electricity is more than just turning on a light switch! Cartoons and color photographs throughout add to the fun.
Grade 3-6-This attractive book covers the basics of electricity. An introduction emphasizes safety first and puts forth a complete list of supplies, most of which are readily available at home or from a hardware store. Levine and Johnstone present the history and theory behind static electricity, and explore electricity step by step through various concepts such as capacity, conductivity, flow of electrons, magnetism, and resistance. The history of research on the properties of electricity, nomenclature, and the construction of a basic circuit board are included. Full-color photographs and drawings extend the text. This volume complements Bob Bonnet and Dan Keen's Science Fair Projects with Electricity and Electronics (Sterling, 1996).
