2. What is a Mixture?
A mixture is combination of different substances, the amount of the parts can vary.

3. Types of Mixtures Homogeneous – looks the same throughout
Heterogeneous – can see the different parts

4. What is a Solution? Solution – a liquid mixture
Solubility – how well something dissolves
Solvent – the liquid doing the dissolving (water)
Solute – the solid being dissolved (salt)

5. Separating Mixtures
Depending on what the mixture is made of there are several ways to turn it back into the basic parts.
5 ways
Filtration
Evaporation
Magnetism
Chromatography
Distillation

6. Examples of Separation
Filtration – large particles stay on the filter paper or in the funnel, while small passes through.
Evaporation – heating a solution until the solid remains in the dish.

7. Examples of Separation
Magnetism- using a magnet to attract some of the mixture.
Chromatography – uses special paper to pull the solvent up and the parts are attracted at different strengths.

8. Examples of Separation
Distillation – the solvent is heated and some of it evaporates into a gas. The gas is collected, cooled and condensed back into a liquid.
