Thermocolour paper
Thermocolour paper changes colour depending on the temperature, providing a striking visual
means of displaying temperature changes. The film responds quite rapidly. It can be used to
illustrate many concepts linked with heat and temperature, including friction, conduction,
insulation, feeling hot and cold, convection, radiation, evaporation and the greenhouse effect.
Tips on its use
Before students use the themocolour paper for the first time, they should spend a little time
becoming familiar with it. Putting the cards on the fingertips allows the range of colours
produced as the film warms up to be seen – from black to brown to green to blue. It is important
to note that the dark blue colour seen when it is hottest is quite similar to the black colour seen
when it is cold.
