Awesome Experiments in Electricity & Magnetism
These simple, fun experiments in magnetism and electricity will get kids all charged up. Test out a kitchen magnet and watch what it attracts; "light the light" with a fluorescent bulb and a piece of wool; "see" invisible magnetic fields and find the strongest part of the magnet; paste things together with static glue; make your TV screen snap, crackle, and pop; and transmit Morse code with a station you build yourself. Almost all the materials are easy to find in the house or inexpensive to buy, and each experiment has a section that explains the underlying scientific principles--plus, they're all safe. This collection is absolutely electrifying!
