School Library Journal Review

Gr 1-3-These two lively books include easily accomplished experiments designed to make children aware of the existence of scientific laws. Each one has 13 busy spreads with colorful watercolor-and-pencil illustrations and large print. The headings on the left pose a question, which is then answered in a paragraph. The rest of the page is devoted to further explanation and illustrations. The right-hand pages give relevant experiments, using very simple materials. The steps are numbered, and warnings are given when appropriate. Color asks such questions as "What's in my box of paints?" The brief answer discusses pigment and absorbed and reflected light. The accompanying experiment produces a twirling color wheel. Center of gravity is demonstrated in "Why do towers topple?" The explanation of "What makes my top spin?" is oversimplified in that it does not discuss transfer of energy, nor does the discussion of wheels, although the "What makes toys go?" section does briefly discuss the stored energy in a spring. In Counting Sheep, the age-old question "Why do I have to go to bed?" is adequately answered in a paragraph about sensory data being sorted and stored and the harmful consequences of sleep deprivation. The accompanying experiment helps children find their best time of day for learning. Other spreads deal with light, clothing materials, bedroom critters, curtain opacity and glass transparency, night fears, equilibrium of a cradle, and moonlight. Jean Potter's Science in Seconds with Toys (Wiley, 1998) offers better explanations of science concepts than these books, but the projects here are more creative.-Lynda Ritterman, Atco Elementary School, Waterford, NJ (c) Copyright 2010.
