K-Gr 2-Two welcome additions to a prolific series designed to educate and stimulate young learners. In the first book, Branley explores magnetism and the uses and history of magnets. Several simple experiments allow for hands-on, empirical verification of concepts. The illustrations, the tone of the text, and the device of a helpful mouse add appeal to a subject that may have had a limited audience. The second title, which is complemented by Lloyd's artful renderings, examines camouflage as an animal defense. Each spread shows several creatures blended into their natural environment; all of them are accurately illustrated and clearly identified. The final pages invite readers to take a closer look at the world around them and discover hidden life. These titles are well-designed, written, and illustrated. In both books, the information is relevant and succinct. These beautiful and simple introductions to science will appeal to any child who has ever asked, "Why?"-Christy Norris, Valley Cottage Library, NY

Branley practically wrote the book on bringing science down to kid level. This entry in his Let's-Read-and-Find-Out-Science series smoothly describes how magnets work and includes a couple of nearly foolproof experiments for making a magnet and a compass. Kelly's illustrations are always a delight--as they are here--employing bright, splashy watercolors that make scientific exploration look like the fun it ought to be. (Reviewed November 1, 1996)

Branley's nicely constructed demonstration includes experimenting with magnets, magnetizing a sewing needle, explanations of the earth's iron content and the magnetic attraction of opposite poles, examples of the ways the compass is used, and an account of the ancient discovery of magnetite (lodestone). Kelley's happy line drawings incorporate a humorous mouse to add safety warnings and goofy side comments.
