Text and photographs present inclined planes and their function as a simple machine.
Children's LiteratureThis 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 inclined planes in daily use (stairs, a child in a wheelchair using a ramp, another lifting a bike up a curb and then using a driveway ramp). 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
