We create an underwater volcano by placing a conical flask of hot coloured water in a tank of cold water.

We use two cans, one painted black and the other painted white, to investigate heat absorption.

We use a metal box holding rods of different materials to test their ability to conduct heat.

We create a cloud in a bottle using warm water and smoke.

We use a metal ball and hoop to demonstrate heat expansion.

We use two cans, one painted black and the other painted white, to see how quickly they lose heat.
