Physics
Heat conduction rods, 4 x metals
Set of four rods in steel, brass, aluminum and copper in the same holder. Each rod is equipped with a liquid crystal indicator that turns green at approx. 40 °C and where the green temperature indicator moves up the rod in step with heat conduction in the metal. Max. working temperature approx. 100 °C; after cooling the experiment can be repeated.

Miscellaneous
Heat radiation bottles
To demonstrate the importance of color for heating and cooling.
Fill with cold water and place near a strong light source, possibly in the sun. The increase in temperature over time shows the importance of the color for the absorption of radiant energy. Similarly, with warm water first – a light source is not necessary.
