Key Stage 2
Meaning
Separating Mixtures is when you take out one of the substances from a mixture.
About Separating Mixtures
- Different mixtures need to be separated in different ways:
- Sieving
- Filtering
- Evaporating
Examples
| Beach | Muddy Puddle | Sea Water |
 |
 |
 |
| You can separate the sand from the pebbles with a sieve. | You can separate mud from water in the puddle with filter paper and a funnel. | You can separate salt from the water by evaporating the water in an evaporating dish. |

Key Stage 3
Meaning
Separating Mixtures is when you take out one or more of the substances from a mixture.
About Separating Mixtures
- All mixtures can be separated without a chemical reaction.
- There are several methods of separating mixtures that you should know:
Examples
| Filtration | Evaporation |
 |
 |
| A mixture or a liquid and an insoluble solid can be separated by filtration. | A solute can be recovered from a solution by evaporating away the solvent. |
| Distillation | Chromatography |
 |
 |
| The solute and solvent can be separated by distillation. | When there are more than 1 solutes in a solution chromatography can separate them. |
