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.

The Perfect Introduction to Temperature and Conduction.

Brass ball mounted on brass rod for thermal expansion experiments.

Two investigative areas covering six STEM activities.

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

For demonstrating the differential expansion of two metals as shown by the curvature produced when the bar is heated. Each metal band is 200 x 15mm and riveted together.

Hands-on STEM learning kit for launching rockets using a simple chemical reaction.

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.

Create and learn how bridges are engineered to make our life easier.

Demonstrate the Difference Between the Specific Heat of Objects.

High quality linear expansion apparatus to study thermal expansion.

Radiometer with four lightweight metal arms.
