I know that when a solid changes to a liquid it is called melting.
I know that when a liquid changes to a solid it is called freezing.
I know that when a liquid changes to a gas it is called evaporation.
I know that when a gas changes to a liquid it is called condensation.
I know that melting, freezing, evaporation and condensing involve a change of state and that all changes can be reversed

I can identify the pattern in data and use this to make predictions
