Gr 4-6-These inviting, clearly written biographies are packed with information. Each book has 12 brief chapters and starts with the subject's childhood. Each section has a "Here's the science" side box to clarify the text. For example, in Curie, transmutation, measuring radiation, and half-life are explained, and in Bell, Morse code, tuning fork, and telephone exchanges. The latter title also has several "Try it yourself" activities, including making a speaking tube and a string phone. The busy layouts are crowded with color cartoon illustrations and the subjects' personal thoughts and feelings. The pictures show, for the most part, happy, sometimes silly-looking people. The illustration of Pierre Curie being killed by a horse-drawn wagon verges on the comical, bringing inappropriate levity to a tragic event. Glossaries are good. Despite the somewhat distracting graphics, these titles offer plenty of facts for report writers.-Anne Chapman Callaghan, Racine Public Library, WI Copyright 2006 Reed Business Information.
