Learning Intention: Students will understand that the different properties of substances allow them to be separated in different ways – particle size, density, magnetism etc.
Success Criteria: Students will be able to identify 10 different methods of separation and give an example of each. They will be able to draw a flow chart to separate a mixture of sand, salt, rice and iron filings.
This term in Year 7 Science you will be starting a unit of work on Separating mixtures. You will be learning about the following processes and how they are used when separating mixtures:
- Froth Flotation
- Gravity Separation
- Magnetic Separation
Can you think of some examples of how these methods are used in the home and in the workplace? At the end of this unit of work you will be asked to separate a mixture of salt, sand, rice and iron filings. Download a worksheet to check your understanding of the definitions for each of these processes here: Separating Mixtures worksheet
