2. Sieving
can separate large particles from small particles
The sand and rock mixture is shaken through.
The small holes in the sieve let the sand
particles pass through and prevent the larger
rocks from passing through.
3. Filtration
can separate solids that are insoluble from a
liquid.
a. Filter paper – particles gathers in the filter paper and water
passes through
b. Funnel – channels the water into the flask
c. Flask – gathers the water after filtration
4. Evaporation
can separate solids that are soluble from a
liquid.
Condensation
Condensing is when water vapour changes into
liquid water
Evaporating dish- water evaporates into the air, leaving
only the salt.
5. Chromatography
can separate different colour dyes.
Distillation
Can separate a solvent from a solution.
Paper- spots of ink are placed on a pencil line. Solvent soaks
up to the ink and each colour sip upwards at a different rate
