"Ward's Phenomena Lab Activities"

Demonstrate the Force of Air Pressure Without a Vacuum Pump

Bring Some Heat Into the Classroom

Ideal for studying heat and thermodynamics.

Apparatus to study convection of gas.

Metal cylinder set for demonstrating density investigation and specific heat experiments.

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.

Solar furnace ideal for demonstrating solar energy.

Understand Color and Heat Absorption.

Gain an understanding of materials science and liquid crustals and how they can be used in a variety of technologies.

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.
