(4) K-3 Flintstones Explain Simple Machines series. Illustrated by Paco Sordo. Fred Flintstone describes the basic workings and everyday uses of simple machines in these cartoon books. Small inset photos of modern real-world examples connect readers to sound factual material, but the text format--paragraph-long word bubbles of tin-eared dialogue ("something tells me today is going to be a great day for using pulleys") in small type--is cumbersome.

(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.
