"Ward's Phenomena Lab Activities"

Sized For Student Use.

Bimetallic strips attached to wood blocks to study thermal energy.

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 new way to demonstrate thermal expansion in a metal.

High quality linear expansion apparatus to study thermal expansion.

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

Radiometer with four lightweight metal arms.

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.

Simple Thermocouple for demonstrating wide range of temperatures.

Ideal for Individual Study
