"Ward's Phenomena Lab Activities"

Bimetallic strips attached to wood blocks to study thermal energy.

Functional glass model of steam turbine.

Sized For Student Use.

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.

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.

Radiometer with four lightweight metal arms.

Versatile Material for Remarkable Results

Simple Thermocouple for demonstrating wide range of temperatures.
