Operating the Models and Experiments

Once a model is assembled, refer to the Instruction Booklet for specific experiments and activities designed to demonstrate scientific principles. Each model provides unique learning opportunities.

The Balance Model:

The balance model allows for exploration of first-class levers and equilibrium. Use the included weights or other small objects to observe how different masses affect balance and leverage points.
