Children have previously learnt:
● to compare and group materials according to whether they are solids, liquids, or gases (Year 4
Chemistry – States of matter)
● to recognise how temperature changes may cause materials to change state (Year 4 Chemistry
– States of matter)
● about the processes of evaporation and condensation in the water cycle (Year 4 Chemistry –
States of matter)
● about pollution (Year 4- Living things and their habitats
● to compare and group everyday materials on the basis of their properties and give reasons for
the particular uses of materials (Year 5 Chemistry – Properties and uses of materials).
In this module, children will learn to:
● that some materials dissolve in liquid to form a solution, and describe how to recover a
substance from a solution
● to use knowledge of solids, liquids, and gases to decide how mixtures might be separated,
including through filtering, sieving and evaporating
● to demonstrate that dissolving, mixing and changes of state are reversible changes
● to explain that some changes result in the formation of new materials and that this kind of
change is not usually reversible, including changes associated with burning and the action of
acid on bicarbonate of soda.
This prepares children for later learning:
● about chemical reactions of different types.
