Description
In a series of fun and involving hands-on physics experiments, kids charge an object with static electricity, demonstrate how static charges produce sound, use magnetic force to suspend a paper airplane, determine that objects in water have a different weight than they do in air, and learn how a substance's buoyancy can be changed. They will also determine if shape determines the strength of an object, learn the effect that an object's center of gravity has on motion, demonstrate how the length of a pendulum affects the time of each swing, and discover how the center of gravity is also the balancing point of an object. Featuring color illustrations and safe, simple step-by-step instructions, Janice VanCleave again shows just how much fun science can be.
