Thermal Camera images
These videos show thermal camera imagery detecting hot and cold heat energy. To conduct an experiment of these kinds in the classroom, you will simply need a thermal imaging camera.
The bench gets warmer when a hand is placed on it. The hotter section of the bench transfers heat to the cooler surroundings and the hand print slowly fades.
The cold ice cubes appear as blue on the thermal imaging camera.
People are, of course, warm!
