(b) Filtration: Mixture of sand and water is passed through a filter paper (a filter with very fine pores). Sand particles being larger in size are retained by the filter paper and get separated from water.

In this method we use a filter paper which is fixed in funnel. Then the mixture is poured on the filter paper. Mud particles being larger in size will remain on the filter paper whereas clear water will pass through it.

(b) Impurities settled at the bottom when muddy water was kept overnight in abucket. The clear water was then poured off from the top. The process of separation used in this example is called ________.

This Chapter introduces you to methods of separation such as hand-picking, winnowing, threshing, sieving, sedimentation, decantation, filtration and evaporation. This Chapter will make you understand the process of separation by using real-life examples, such as separating husk and stones from grains, separation of solids from liquids etc.

When two or more substances are mixed together they form a mixture. Components of a mixture should be separated because some components may not be useful or may spoil the useful component of the mixture.

The method of separating the components from a mixture is known as winnowing. In this method, heavier and lighter components of a mixture are separated by wind or by blowing air. This method is used by farmers to separate lighter husk particles from heavier seeds of grain.

Sieving is a method in which fine particles are sieved through holes of the sieve while the bigger impurities remain on the sieve.
