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

This unit visually reinforces heat conductivity lessons.

The Student Coin and Feather Tube shows the two items in a vacuum, falling at the same rate.

This apparatus is useful for studying forces during thermal contraction and expansion.

Appropriate for grades 6 to 12 Brings the First Law of Thermodynamics to life! This pair of precision-machined, chrome-plated steel balls is actually a hands-on demonstration in energy transformation. By striking the balls together, you will create enough heat at the point of contact to burn a hole in a sheet of paper.

Solar furnace ideal for demonstrating solar energy.

A new way to demonstrate thermal expansion in a metal.

Various rods to explore thermal conductivity.

Study the motion and behavior of gas molecules with this intriguing demonstration. An electric motor, running at 4 to 12 V DC, vibrates a small platform inside a transparent tube. This platform then violently vibrates the many small stainless steel balls inside the tube.

The Precision Linear Expansion Apparatus produces accurate determinations of the coefficient of expansion.
