Two slim volumes offering a dozen or so science experiments on a variety of topics. Subjects are introduced with definitions and explanations of the project's purpose. Instructions are numbered, with accompanying colorful illustrations adequate for checking progress. Unfortunately, the indexes are confusing because they are integrated with unnecessary glossaries. In How Things Work , students can build a kite, a compass, or a rocket boat; they can design simple machines or see how jet engines react. A fine checklist of safety tips is positioned opposite the table of contents. Is It Magic? features experiments in creating optical illusions. Water is a major component in many of these tricks, but there are also the familiar line and silhouette foolers worked from paper. For magic and excitement at its best, complement this experiment book with Baum's Opt: An Illusionary Tale (Viking, 1987), in which the eye travels to a magical land through optical marvels. Scienceworks (Addison-Wesley, 1988) offers 65 experiment puzzles and tricks that this age group would also enjoy. --Ellen Dibner, East School, Long Beach, NY
