In the Separation Techniques unit, pupils will build on their knowledge of solutions to learn about methods for separating mixtures, including filtration, evaporation, distillation, and chromatography.

In the Solid, Liquid and Gas States and Changes of State unit, pupils learned to categorise substances into the solid, liquid or gas state and explored particle behaviour during changes of state.

This unit explores the concepts of pure substances, mixtures, and diffusion in liquids and gases. It emphasises accuracy, precision, and the use of appropriate techniques during investigations. The focus is on making predictions and recording reliable observations.
