Most children will:
name and describe examples of the main processes associated with water changing state and recognise that these processes can be reversed; explain the water cycle in terms of these processes; use patterns in data to make predictions
Some children will not have made so much progress and will:
describe how to change water into ice and steam and steam into water; describe a few examples where these changes occur, and recognise patterns in data
Some children will have progressed further and will also:
explain how changing conditions affects processes such as evaporation and condensation, and give reasons for predictions made using patterns in data
