KS1 & KS2 science curriculum

This unit builds on pupils' prior learning from Properties, changes and separating materials, where they explored the properties of materials and how they can be changed and separated. In Materials, pupils will delve deeper into methods of separating materials, such as filtering and evaporation. This prepares them for the next unit, Solutions, where they will apply their understanding to explore how different materials dissolve and interact in various mixtures, reinforcing their knowledge of material properties and solutions.

1. Comparing rock salt with table salt (non-statutory)
2. The effect of adding salt to ice: plan (non-statutory)
3. The effect of adding salt to ice: do and review (non-statutory)

• Know that some materials will dissolve in liquid to form a solution, and describe how to recover a substance from a solution
• Use knowledge of solids, liquids and gases to decide how mixtures might be separated, including through filtering, sieving and evaporating
• Demonstrate that dissolving, mixing and changes of state are reversible changes
• Explain that some changes result in the formation of new materials, and that this kind of change is not usually reversible
