Simple Machines - Lever

The Lever Model is a simple yet powerful demonstration of how levers help lift or move loads with minimal effort. Designed with a clear pivot point and movable lever arm, students can adjust lengths and weights to understand how distance from the fulcrum affects the force needed. Perfect for classroom experiments, this model is crafted for durability and consistent performance.

Educational benefits:

• Demonstrates mechanical advantage through force and distance
• Reinforces key physics concepts in an engaging, hands-on way
• Encourages hypothesis development and testing
• Makes abstract physics content tangible and visual

Classroom activity ideas:

• Explore how changing arm length alters required force
• Compare first, second, and third-class lever setups
• Challenge students to lift various weights using minimal force
• Connect classroom findings to tools like bottle openers and scissors
