LESSON C ONCEPT Another method of separating mixtures is sieving. It is a simple technique for separating particles of different sizes. A sieve such as used for sifting flour has very smal holes. Coarse particles are separated or broken up by grinding against one-another and against screen openings. Depending upon the types of particles to be separated, sieves with different types of holes are used. Materials one-fourth (¼) kg flour one (1) strainer/sifter one (1) plate/bowl What to do: 1.
