The force is with us--experiments in force and motion prove it! Demonstrate inertia with a Card Shot trick, and by observing whether a fresh or hard-boiled egg stops spinning first. Use a cardboard rocket ship to find the center of gravity, make a "great salt lake" to display buoyancy, examine air currents with a water tower; and try balloon cars that create motion madness. Ordinary, easy-to-find materials will get you moving on these fun-filled investigations. 160 pages, 50 b/w illus., 6 x 9.
