Effective Method of Showing Normally Invisible Currents

Brass ball mounted on brass rod for thermal expansion experiments.

Bimetallic strips attached to wooden handle to study thermal energy.

This is a classic example of thermodynamics in action.

Sized For Student Use.

A new way to demonstrate thermal expansion in a metal.

The Student Double-Wall Calorimeter is an inexpensive necessity for your experiments.

This unit visually reinforces heat conductivity lessons.

High quality linear expansion apparatus to study thermal expansion.

Radiometer with four lightweight metal arms.

Demonstrate transformations of energy - thermal, electric, and kinetic - with this amazing device.

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.

Laminated for long use.
