I know that ice melts when it gets too warm and that liquid water turns into solid water (ice) when it gets too cold.

I know what mixtures are (e.g. salt & sand, water & salt etc.) I can put different materials into different groups (solid, liquid, gas).

I can classify materials as soluble or insoluble.

I know that when water is heated or cooled the change involved is reversible. 

I know that we can get solid salt from a salt solution by evaporating off the water (you cannot use filtration).
