In this unit pupils:
- extend their knowledge of dissolving and the separation of the components of a solution and relate this to particle theory
- begin to distinguish between a 'pure' substance and a mixture
- apply the particle model of solids, liquids and gases in a range of contexts
In scientific enquiry pupils:
- make measurements of temperature and mass
- describe and interpret patterns in graphs and chromatograms
- make predictions from graphs and data about solubility
- investigate how a sample of pure salt can be obtained from a sample of rock salt, evaluating the method in terms of salt obtained
This unit is expected to take approximately 8 hours.
