How can you tell they’ve got it: Separating Mixtures?

If they’ve got it, you’ll see things like: Selects the correct separation technique for a given mixture with justification; Describes the steps of simple distillation and explains why it works; Interprets a chromatography result (Rf values, number of components); Explains why filtration removes sand from water but not salt. Or just try it together: If your child needed to separate salt from sand mixed together in water, could they describe two stages of separation, the equipment needed, and explain why each step works?

Separating Mixtures

Your child can pick the right way to split a mixture. A filter removes sand from water. Boiling and then cooling the steam, called distillation, separates liquids.

In curriculum terms

Select and carry out appropriate separation techniques for different types of mixtures: filtration (insoluble solids), distillation (liquids by boiling point), crystallisation (dissolved solids), and chromatography (coloured substances)
