Separation methods help us to separate out a mixture
How we separate the mixture depends on what's in the mixture!
5
For example...
Say you went to the beach! You used your bucket to scoop up some water but realised there was a lot of sand in there...
What could you do?!
6
Multiple Choice
7
Sand is insoluble!
This means that the sand will NOT dissolve in the seawater!
So, you can see and touch the sand in the bucket - so how could you separate this mixture in the lab.
8
Multiple Choice
Describe how you could separate an INSOLUBLE material (e.g. sand) from a solution.
9
Filtration
Filtration is used to separate an insoluble substance from a solution.

Success!
You have managed to remove the INSOLUBLE sand from your mixture! All that filtering has made you thirsty, so you decide to take a sip...
15
YUCK!
The water is salty!
16
Multiple Choice
17
That's right! Salt is soluble!
Something that is soluble CANNOT be removed by filtration! What should you do now...?

19
Crystallisation!
This helps me evaporate all of the water in a solution and just leaves the soluble material (e.g. salt).
