Science

In the Patterns in the periodic table unit, pupils will build on this knowledge to learn how the chemical and physical properties of different elements are indicated by their position on the periodic table and about key groups of elements. 

In the Solutions unit, pupils learnt about mixtures, solutions and dissolving in terms of the particle model.
