Separating Mixtures Mixing sulphur and iron. . . how could you separate this mixture?
Separating Mixtures
Do not put magnetic directly on iron Hold the magnet below the Petri dish Sulphur + Iron mixture Petri dish Magnet
Separating Mixtures You’re stranded on a desert island surrounded by sea water, sadly your science teacher is lost at sea but luckily all your science equipment has washed up. . . how could you separate a mixture of sand, salt and water to get drinking water?
Goal: to extract clean fresh water Come up with a plan, you will need: - A list of equipment - A series of steps You should be able to explain your reasoning for each step, use your science knowledge! You have 10 minutes
