Bring the 2nd Law of Thermodynamics to life.

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.

Bring Some Heat Into the Classroom

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

This new conductivity bar set features sensitive liquid crystal temperature indicators, which are attached to the front of each of four metal bars.

Apparatus to study convection of gas.

Ideal for studying heat and thermodynamics.

Organize the study the disorder.

Vividly illustrate the transformation of energy.

Versatile Material for Remarkable Results

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.

A hands on visual of converting heat to power.

Various rods to explore thermal conductivity.
