I have participated in practical activities to separate simple mixtures of substances and can relate my findings to my everyday experience. 

SCN 2-16a

Benchmarks:

· Draws on findings from practical investigations to explain how a mixture of solids of different sizes can be separated using a sieve or magnet, for example, sand and peas or salt and iron filings.

· Selects the most appropriate practical technique for separating insoluble solids, for example, filtering or sieving.

· Explains why a dissolved solid cannot be separated from the solvent by filtering but can be separated by evaporation.

· Uses scientific vocabulary such as ‘soluble’, ‘insoluble’, ‘dissolve’ and ‘solution’ in context. 

· Relates findings of practical investigations about dissolving to everyday experiences, for example, recycling, salt production and water purification.
