Editorial Reviews

Children's Literature
This entry in the "Early Bird Physics" textbook series explains what work is, defines the simple machine under discussion, introduces special terminology such as fulcrum, friction, or axle, and shows variations on that machine that make it more complicated. Simple hands-on activities explore some of the properties of a screw and illustrate ways screws are configured to increase or decrease the force needed to turn them. A multiracial cast of children who look to be about nine or ten are photographed in posed situations to illustrate concepts and most of them look realistic. Diagrams also help children see where force is applied or what can be altered to make work easier. An endnote to adults suggests helpful discussion questions and ways to explore the vocabulary specific to this machine while a bibliography of other books on the topic and two generic websites suggest further exploration. A glossary and index with a note on how to help children use these sources are added as well. All in all, the books in this series present solid support for adults in introducing simple machines to elementary age children. It is an appealing package children can also read for themselves. 2002, Lerner Publications, $23.93. Ages 7 to 10. Reviewer: Susan Hepler
