- 1Sieving method in which two or more components of different sizes are separated from a mixture on the basis of the difference in their sizes. You can separate sand and gravel with this technique.
- 2Evaporation process whereby atoms or molecules in a liquid state gain sufficient energy to enter the gaseous state. You can separate salt and water by evaporating it.
- 3Distillation Process of separating the components or substances from a liquid mixture by using selective boiling and condensation. An example can be the purification of alcohol.
- 4Decantation Process of pouring away a liquid while leaving a solid behind. You can separate oil and vinegar.
- 5Crystallization Natural process which occurs as materials solidify from a liquid, or as they precipitate out of a liquid or gas. An example can be turning water into ice.
- 6Filtration Process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of some substance, called a filter. An example can be the separation of water and bacterias.
- 7Magnetism Power to attract. It refers to the attraction to iron and other metals in electric currents and magnets. You can separate components from recycling, isolate metals, and purify ores.
- 8Paper Chromatography Technique for separating dissolved chemical substances by taking advantage of their different rates of migration across sheets of paper. An example can be to identify finger prints.
- 9Centrifuging Technique which involves the application of centrifugal force to separate particles from a solution. Centrifugation of protein solution, for example, allows elimination of impurities into the supernatant.
