Sorting
Separating mixtures with your hands.
Ex: separating pop corn kernels, black beans, & riceSlide3
2.
Using a Magnet
Using the magnetic property of a substance to separate a mixture
Made of iron
Ex: Iron Filings & pencil shavingsSlide4
3.
Chromatography
-Separating a colored mixture by using a solvent to see what colors make it up.
Ex: Black markerSlide5
4.
Filtration
Separating by size
A
llowing liquids or smaller items to pass through a filter, leaving a larger substance on the other side.
Ex: sand &
w
ater; rocks & dirtSlide6
5.
Dissolving a Substance
Mixing substances in water to separate the one that dissolves.
Ex: Sand & Sugar Slide7
6.
Evaporation/Boiling/Simple Distillation
Separation by changing a liquid to a gas to leave behind a dissolved substance
Ex: lemonade Slide8
7. Fractional Distillation
Separates liquids by using their different boiling points
Ex: water (100ᴼC) and ethanol (78ᴼC) Slide9
Sand, Salt, Iron Filings Mixture
Procedures for separation:
(be very detailed)
1. Take out the iron filings with a magnet.Slide10
2. Pour the sand and salt in water so that the salt will dissolve.
3. Use a filter to separate the salt water from the sand. Slide11
4. Evaporate the water out of the salt water which will leave the salt behind. Slide12
