Simple Machines

Ray Doiron is an assistant professor in the Faculty of Education at the
University of Prince Edward Island.

This accessible book outlines 13 science activities designed to teach
primary children about six simple machines: lever, pulley, inclined
plane, screw, wedge, and axle. A simple question is used to pique
children’s curiosity and start them thinking about the topic. This is
followed by a list of basic materials needed for the activity and by a
“What to Do” section that gives clear, precise directions for
completing the activity. The activity concludes with “What’s
Happening,” a simple explanation of the phenomenon demonstrated.
Sidebars and colorful photographs make the presentation inviting for
children.

The interesting and fun activities featured in Simple Machines make it
a valuable resource for teachers and parents alike. Recommended.
