Grade 4-7-Hauser gives directions for creating a lot of gadgets, gizmos, contraptions, and doohickeys constructed with stuff often found in cupboards, closets, garages, and "junk" drawers. Materials such as plastic soda bottles, marbles, buttons, straws, and cardboard tubes are cut, trimmed, shaped, and bent as a way to be glued, stapled, sewn, and taped. They are ultimately formed into objects being tossed, balanced, spun, flung, and strung-all to indicate various principles of physics. Also included are nudges to encourage individual forays in the worlds of problem solving and inventing. Fun to make-and probably fun to experience with-the crafts, if followed sequentially, introduce such basic topics as motion, energy, balancing, and gravity. Even though used as random crafts, they will result in questions regarding the predictable behaviors for these objects as boomerangs and yo-yos. Classroom teachers can team this with Vicki Cobb's Why Can't You Unscramble an Egg? (Lodestar, 1990; o.p.) and Bernie Zubrowski's Raceways: Having Fun with Balls and Tracks (Morrow, 1985; o.p.).

Using simple things around the house to generate toys that spin, fling, collide, and whiz, kids will grasp the basic principles of concepts of gravity, inertia, balance, and energy. Projects are incredibly hands-on. Most activities can be completed with minimal assistance. Every page is jam-packed (in age-appropriate vocabulary) with factoids, fun facts about famous inventors, and inspiration for science lovers of most ages. A 1999 Parents' Choice® Silver Honor.
