How Do You Lift a Lion?
How do you lift a lion? With a machine that's big and powerful with clanking metal parts? There are machines like that. But others have only a few moving parts. In fact, some machines are so simple that they don't seem like machines at all--like the wheel, the lever, and the pulley. These machines can make work easy--even if you're trying to lift a lion!

"This book is an introduction to three simple machines: the lever, the pulley, and the wheel. Lifting lions, pulling pandas, and raising a basket of bananas are the tasks the devices are used for. The humorous illustrations both inform and amuse the reader."--The Horn Book Guide
"A 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)."--School Library Journal
