Bimetallic strips attached to wooden handle to study thermal energy.

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

Brass ball mounted on brass rod for thermal expansion experiments.

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.

Bring Some Heat Into the Classroom

High quality linear expansion apparatus to study thermal expansion.

Radiometer with four lightweight metal arms.

Understand Color and Heat Absorption.

A set to demonstrate the rise in temperature when a fixed mass of gas is compressed.

Ideal for studying heat and thermodynamics.
