Demonstrate the importance of pulleys by turning your students into giant human pulleys! Students hold onto pulley rods and investigate the setup and properties of different pulley systems. Students will actually feel the effects of abstract concepts, such as mechanical advantage and force. Participating in this active demonstration will truly “pull” these fundamental concepts together for your students! Includes complete instructions and a reproducible student worksheet.
Concepts: Pulleys, simple machines, mechanical advantage.
Time Required: 20 minutes
