"AP physics"

This activity illustrates the relationships of mass, potential energy, and kinetic energy with marble races.

Large scale demonstration of harmonic motion.

A Staple For Optic Studies

Easy to Study Inertia and Mass

The refraction tank with laser provides excellent visibility!

Excellent pads for friction rod experiments

Useful for collision and pendulum experiments.

Dramatically Demonstrate that Temperature Increases with Pressure

Easier to Use and Clean Up than Iron Filings.

Ideal for demonstrating that vapor pressure increases when temperature increases.
