Description

This editable differentiated lesson pack focuses on observing and classifying solids based on how they behave when mixed with water. Children explore dissolving by watching sugar break into tiny particles and spread through the liquid to form a clear solution, then compare this with solids like sand and flour that remain visible. In the main activity, pupils test a range of solids, record careful observations, and decide whether each one is soluble or insoluble. The lesson builds accurate scientific vocabulary, strengthens close‑observation skills, and helps children explain the difference between mixtures and solutions using real evidence.

The file includes the following resources: - editable teaching presentation - editable activity worksheets - editable additional activity ideas - editable lesson plan - editable focus assessment worksheet
