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.
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).
