Science

In the Acids and Bases unit, pupils will build on their understanding of chemical reactions to learn about the properties of acids, bases, alkalis, and the neutralisation reaction.

In the Atoms, Elements and Compounds unit, pupils learned about atoms, elements, and compounds and how particles reorganise in a chemical reaction.
