Science - Particles
Task 1: What are the following used for when separating mixtures?
Sieving:
Filtration:
Evaporation:
2
Task 2: Write down what each of these is an example of (sieving, filtration or evaporation).
3
1. Leaving a mug of milo outside in the sun for a week. | |
2. Straining a tin of corn. | |
3. Leaving a saucepan of tomato soup on the stove until it is dry. | |
4. Pouring hot water with coffee grounds through a coffee filter. | |
5. Pouring the rice and boiled water through a sieve. | |
Task 3: Identify the parts of the mixture to be separated, the process to use and any key equipment you would need.
4
Mixture | Components to be separated | Process | Key Equipment |
Glittery water | | | |
Watercolour paint dissolved in a dish of water | | | |
A bowl of flour and lego pieces | | | |
Task 4: How would you separate a container of shells, sand and water into its components? It may require you to use multiple separation processes.
