Editorial Reviews

Children's Literature
This entry in the "Looking at Simple Machines" series supports national science standards for helping early readers understand simple science concepts. The simple machine is described, and a diagram uses arrows and "force" to show the work being accomplished. Child-friendly examples show the screw in daily use (a lid, a bolt and a lightbulb, although technically it is the "base" of the lightbulb that is the screw, not the whole thing, as the text indicates). Endmatter includes five words defined, some related books, several web sites for more information and an index or word list. The format of one sentence per page invites young readers to use the books for independent reading, but a teacher or adult could lead children to discuss the pictures beyond what the sentence suggests, making the book useful for discussion or basic research. Color photos include children of various ethnicities and are current. 2001, Capstone Press, $13.25. Ages 5 to 7. Reviewer: Susan Hepler
