This book aims to introduce some of the theories of physics to very young readers. The concepts are those of gravity, leverage, friction, and pulleys. Each is accompanied by some physical problem involving animals. For example, the book starts out by asking how one might lift a lion. Answer: put him on a platform and use a lever. Then, if one wants to lift more lions, one would need a longer lever. This is a clever little book, with nice pictures.

Gr 2-4A basic introduction to levers, wheels, and pulleys. As two children lift a lion, pull a panda, and deliver a basket of bananas to a baboon party, Wells offers explanations for how and why these simple machines work. The hand-lettered text identifies technical terms such as fulcrum, force, friction, and other such words (also included in a glossary). One might quibble with some of the statements, such as "Leverage adds force to your own strength." Also the pen-and-acrylic cartoons are mediocre in quality and are merely adequate at depicting the concepts. A great idea with a fair-to-middlin execution.Virginia Opocensky, formerly at Lincoln City Libraries, NE
