Science Fair Projects: Energy

Energy is everywhere! Without even taking a step you can see a dozen kinds: Solar. Heat. Light. Fluid. Sound. Pressure. Electrical. Chemical. Mechanical. Magnetic. Electromagnetic. Gravity. And many more. You'll find 55 science fair projects here, and all are designed as "around-you-science," based on ideas you find right where you are. What's under that old board on the ground? How many rings are in the trunk of that fallen tree? How many stars can you see with your naked eye? By answering ordinary questions like these, you can explore many mysterious worlds. Show what kinds of energy are released in a storm. Point out where your home loses heat in winter or cool air in summer, and how to prevent it. Explain how microwaves heat food without raising the inside temperature of the oven. How your body turns food into energy. How trees act as air-conditioners. Or how a radio takes sound energy out of the air. Every experiment is clearly explained and illustrated. Just remember, the greatest form of energy of all is--your curiosity! 96 pages, 120 b/w illus., 8 1/4 x 11. NEW IN PAPERBACK
