This diver set expresses the effects of air pressure and buoyancy.

Sized For Student Use.

This unit visually reinforces heat conductivity lessons.

Ice Melting Blocks are a unique way to teach principles of conductivity of heat and the scientific method.

A new way to demonstrate thermal expansion in a metal.

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.

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

Brass ball mounted on brass rod for thermal expansion experiments.

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.

Accurately plot the thermal energy transferred by an aluminum bar.

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.
