Review by Horn Book Review

Beginning with real-life examples, this book illustrates and explains the lever, wheel-and-axle, pulley, ramp, wedge, and screw. Both the order and the language are clear, but what sets this book apart is the artwork: bright, spare cartoons and line drawings have just enough detail and humor to simultaneously clarify and engage readers. A single experiment is included. Glos. (c) Copyright 2016. The Horn Book, Inc., a wholly owned subsidiary of Media Source, Inc. No redistribution permitted.
