Simple Machines - Fulcrum Balance

The Fulcrum Balance model is an ideal tool for exploring the mechanics of levers and equilibrium. With its long lever arm and central pivot point, this model invites students to investigate how the distribution of mass affects balance. By moving weights and adjusting distances from the fulcrum, learners gain an intuitive and measurable understanding of torque and mechanical advantage.

Educational benefits:

• Teaches principles of balance, torque, and lever mechanics
• Encourages mathematical reasoning through measurable outcomes
• Supports open-ended inquiry and hypothesis testing
• Enhances understanding of real-life tools such as seesaws and scales

Classroom activity ideas:

• Predict and test balance points for various weight combinations
• Compare symmetrical vs. asymmetrical loading
• Explore what happens when the pivot point is shifted
• Use the model to simulate common tools like a crowbar or beam balance
