Why Do Elephants Need the Sun?

Gr 2—5—Wells presents such concepts as photosynthesis, gravity, nuclear fusion, and the sun's effect on weather conditions in an appealing, easy-to-understand format. Pen and acrylic cartoon illustrations and simple diagrams strongly support and enhance the text. Information is factual and up-to-date (Pluto is not included with the solar system diagram) and covers the purposes and uses of the sun over the years, from telling time to generating electricity. By using the elephant to relate the level of importance the sun plays in the lives of all living things, Wells has found a unique way to teach some otherwise difficult concepts. Some readers might stumble over science terms such as "nuclear fusion," "electromagnetic energy," "photosphere," etc., although they are explained in both text and illustrations. The book concludes with 10 comic-strip-style panels of "Did You Know?" interesting facts. Overall, this is an excellent resource for budding young scientists.—Cathie Bashaw Morton, Millbrook Central School District, NY
