Thermal expansion of different metals.

This unit visually reinforces heat conductivity lessons.

Various rods to explore thermal conductivity.

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

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

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.

Bring Some Heat Into the Classroom

This working model thermostat will demonstrate how differential expansion is used to control temperature. A bimetallic strip is used to open or close an electric circuit when temperature changes. The contacts will carry about three amperes. The unit can be operated with a 6 V lantern battery, low voltage power supply, or a blow dryer. Mounted on a metal base; approximately 15 cm high.
