This editable differentiated lesson pack focuses on separating mixtures to make muddy water clearer. Children learn that mixtures can be undone because the materials do not change, and explore a range of separation methods including scooping, settling, sieving and filtering. In the main activity, pupils use problem‑solving to choose and test different methods in a sensible order, observing what each one removes and recording how the water changes. The lesson strengthens understanding of mixtures, builds confidence in selecting appropriate techniques, and helps children explain their decisions using clear evidence.
