Pupils learn about the changing state of water and the process involved that transform it from a solid to a liquid, from a liquid to a gas and vice versa.
Learning Objectives:
PoS - identify the part played by evaporation and condensation in the water cycle and associate the rate of evaporation with temperature
NaG - pupils should observe water as a solid, a liquid and a gas and should note the changes to water when it is heated or cooled
WS - pupils could research the temperature at which materials change state
