  2. Separating Mechanical Mixtures • Generally speaking, separating mechanical mixtures is easier, because the components of the mechanical mixture are usually quite different from each other.

  3. Filtration • Filtration is the mechanical process of separating solids from liquids or gases using a porous article or mass, such as paper or sand. • When the mixture is poured into the filter, the solid parts are trapped in the filter, and the liquid passes through. • Filtrations is used to separate solids from liquids or gases.

  4. Sorting • Sorting is a technique that involves separating substances on the basis of appearance (e.g. Size, colour, composition) • We should practice this technique to ensure our garbage is put where it belongs!

  5. Sifting • Sifting is a means of separating solids by component size. It involves shaking a solid material while it passes through a screen or mesh. • Components of the solid materials that are small enough to pass through do, separating them from larger components. • Sifting is used to separate solids from solids.

  6. Magnetism • Some metals are magnetic because their component particles are attracted to the particles within magnets • Iron, steel, and nickel are highly attracted to magnets, whereas most other substances are not. Therefore, you can use a magnet to separate magnetic materials from ones which are not.
