How Do You Lift a Lion? : Machines

How Do You Lift a Lion? : Machines

Description

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!
