(4) K-3 Buddy Books: Simple Machines series. Attempting to explain physics to a very young audience, these books wisely follow a simple template involving definition, parts, principles, history, and applications. Some of the color photos, diagrams, and clip art are clear; others, such as a complicated wheel and axle, are confusing. Some definitions are helpful, while others are incomplete (e.g., how a wedge can help fasten is never explicit). Glos., ind. Review covers these Buddy Books: Simple Machines titles: Inclined Planes, Levers, Pulleys, Screws, Wedges, and Wheels & Axles.
