Separation solutions

Explore an array of methods to separate mixed materials back into their constituent parts. Write up your user friendly experiments to include in your education pack and Pinterest page.

Science Objectives
i) Compare and group together everyday materials on the basis of their properties, including their solubility and response to magnets.

ii) Know that some materials will dissolve in liquid to form a solution and describe how to recover a substance from a solution.

iii) Use knowledge of solids, liquids and gases to decide how mixtures might be separated, including through filtering, sieving and evaporating.

iv) Demonstrate that dissolving, mixing and changes of state are reversible changes.

Working Scientifically

1. Plan different types of scientific enquiries to answer questions, including recognising and controlling variables where necessary.
2. Use test results to make predictions to set up further comparative and fair tests.
3. Report and present findings from enquiries, including conclusions, causal relationships and explanations of and degree of trust in results, in written forms.
