From School Library Journal

Grade 3-6-- Appealing frog and lizard cartoon characters move from the cover through the pages of this collection which is arranged by the materials used in the experiments rather than by the scientific principles demonstrated. The introduction assures readers that these experiments all work and are safe; warnings are included about such things as a hot stove and that iodine and ammonia are poisonous. A brief history of the materials and some facts about them introduce the series of experiments. "Clutching at straws," for example, explains straws, shows how to make one, and then demonstrates such principles as air pressure, water refraction, and center of gravity. Included in the chapter on soap and detergent is a recipe for a bubble mix along with the expected making of bubbles and rainbows. --Sylvia S. Marantz, Wellington School, Columbus, OH
