Grade 3-5?Entertaining and instructional series entries. Double-page experiments consist of illustrated step-by-step directions with proper safety cautions, explanations of how or why they work, and suggestions for further exploration. Making Shapes uses shape making and shifting to illustrate concepts from different branches of science. Pushing and Pulling introduces gravity, weight, friction, hydraulic forces, fluid drag, and pulleys. Understanding Electricity uses a 6-volt battery and 6-volt lightbulb along with other simple household products to explain resistance and electroplating as well as the parts of an electric circuit itself. There are also projects showing the effects of static electricity and how batteries work. All three books have full-color photographs and cartoon drawings that are appealing and informative. Youngsters will pursue these titles for fun as well as for assignments.?Margaret M. Hagel, Norfolk Public Library System, VA
