Why this why now
This unit builds on pupils’ prior learning from Solid, liquid, gas states and changes of state, where they explored how particles behave in different states and change under various conditions. It advances their knowledge by investigating how substances mix to form solutions and the factors that affect solubility. This prepares pupils for the next unit, Separation techniques, where they will apply their understanding of mixtures and solutions to learn how substances can be separated, deepening their grasp of the interactions and properties of materials.
Prior knowledge requirements
- Some materials will dissolve in a liquid to form a solution.
- Dissolving is a reversible change.
- Changes of state are reversible.
- Some changes result in the formation of a new substance.
