Year 5 Science – Properties and changes of materials – How can we get the salt out back out of salty water? – Lesson 6

Description

This editable differentiated lesson pack focuses on recovering a dissolved solid from a solution using evaporation. Children revisit why filtering cannot remove dissolved particles, then use research about sea‑salt production to understand how evaporation leaves the solid behind. In the main activity, pupils make a concentrated sugar solution, allow the water to evaporate over time, and record the changes they observe as crystals begin to form. The lesson develops careful observation, links research to practical testing, and helps children explain how evaporation can separate materials in a solution. The file includes the following resources: - editable teaching presentation - editable activity worksheets - editable stop and jot worksheet - editable additional activity ideas - editable lesson plan - editable focus assessment worksheet

National Curriculum objectives Science: Year 5 Pupils should be taught to:
