For demonstrating the thermal conductivities of metals. Consist of strips of copper, aluminium, iron and brass, fixed on a ring, meeting in the center with small cups formed on the outer ends.

For showing convection currents in air. Comprises of metal box, 220x100x100mm with a removable glass front, two chimneys and candle holder fixed to the base of the box beneath the left hand chimney

For demonstrating convection in liquids. Glass tube of 20mm diameter bent into a rectangle of approximate size 38x30cm, fitted with a funnel.

For demonstrating the difference in expansion of different liquids over the same temperature. Consisting of five glass tubes with bulb of equal capacity mounted on a support, with scales and metal trough to hold hot water.

For determining the thermal conductivity of bad conductors. Three copper discs 42mm diameter x 12mm thickness each drilled to support a thermometer. A 6V D.C. Electric heater with wires led out to 4mm sockets and clamped in a wooden frame by means of a plastic screw.

For demonstrating the mechanical effect of reflection and absorption of light and heat. Partially evacuated glass bulb has four vanes which spin on low friction pivot. Alternate vanes are dark and white in colour.

Hollow cube of 125mm side made from tin sheet with an opening at the top. The vertical surfaces are dull black, bright black, white and bright.
