Thermal expansion of different metals.

This unit visually reinforces heat conductivity lessons.

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

Various rods to explore thermal conductivity.

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

A new way to demonstrate thermal expansion in a metal.

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.

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

Bimetallic strips attached to wooden handle to study thermal energy.
