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!
