Part of Picture Window Books' "Amazing Science" series, this book for the library market tries to answer kids' questions about how simple machines work. Included are side bars, fun facts, a glossary, and an activity that builds on the book's lessons. Building on the concept of a simple machine, which is defined as anything that helps people do work, children learn how wheels quickly move people and objects from one place to another. Fire trucks use wheels spinning on axles, but so do skateboarders. Readers are shown how the size of a wheel determines how much weight it can carry. They also learn that gears are wheels with teeth. And that cranks are a kind of pedal that turns wheels. The message reinforced here is that wheels help the world to work and play. The activity uses a spool of thread, string, paper cup, pennies, and pencils to show how wheels and weight work together. The bright, computerized illustrations work nicely with the text to entice young readers to hunker down and dig into the book's concepts.

Gr 1-4-These simple concept books are full of pizzazz and wonderfully illustrated with digital graphics that show kids doing typical kid things. The lumberman on the cover of Cut may not be as enticing as the active children depicted on the other titles. The book also has fewer internal pictures of youngsters, although there is a spread of a boy surrounded by wedges of cake, pie, and pizza. Other spreads depict and discuss doorstops, nails, and airplane wings. In Roll, skateboards, playground slides, and roller coasters are used as examples. Best of all is Scoop, which clearly describes several versions of the lever, found in the playground, garage, and kitchen. Tires discusses wheel sizes, gears, cranks, etc. Unfortunately, "axles" is misspelled on the cover. Each book has an activity and "Fun Facts." The FactHound Web sites listed add more information, but don't take kids to any fun, interactive sites. If you have Sally Hewitt's Machines We Use (Children's Press, 1998) or Anne Welsbacher's "Understanding Simple Machines" series (Capstone, 2001), you may not need these books.-Debbie Whitbeck, West Ottawa Public Schools, Holland, MI Copyright 2006 Reed Business Information.
