Key Stage 2
Meaning
A mixture is when two or more different substances are in the same place or are part of the same object.
About Mixtures
- Many materials are mixtures of different substances.
- Mixtures can usually be separated, but sometimes it is very difficult to do.
- Mixing is reversible change. Once two substances are mixed they can usually be separated again.
Examples
| Sea Water | Muddy Puddle | Beach |
 |
 |
 |
| Seawater is mixture of salt and water. | This puddle is a mixture of mud and water. | The beach is a mixture of sand and pebbles. |
Key Stage 3
Meaning
A mixture is a substance which contains more than one type of chemical.
About Mixtures
- A mixture can be made of different elements or it can be made of different compounds.
- The different chemicals in a mixture are not chemically bonded with each other.
- Mixtures can be separated without a chemical reaction.
Examples
 |
 |
 |
| A mixture of two different elements. | A mixture of two molecular elements. | A mixture of three different elements. |

 |
 |
| A mixture of two compounds. | A mixture of a compound and an element. | A mixture of a compound and an element. |
Key Stage 4
