Setup

Description: Using this kit, students learn about force, measuring work, inclined plane or ramp, mechanical advantages, different classes of levers, pulleys, and axles. The kit provides oversized hands-on materials for teaching simple machines. Oversized materials make teaching K-3 about simple machines easy and fun.
