1. Filtration: This method is used to separate a solid from a liquid. The mixture is poured through a filter paper, which traps the solid particles while allowing the liquid to pass through. Examples: separating sand from water, making coffee.

2. Evaporation: This method is used to separate a dissolved solid from a liquid. The mixture is heated, causing the liquid to evaporate and leave the solid behind. Examples: separating salt from saltwater, drying clothes.

3. Magnetism: This method is used to separate magnetic materials from non-magnetic materials. A magnet is used to attract the magnetic material, leaving the non-magnetic material behind. Examples: separating iron filings from sand, recycling metal.

4. Decantation: This method is used to separate a solid from a liquid when the solid settles to the bottom of the mixture. The liquid is carefully poured off, leaving the solid behind. Examples: separating sand from water, removing sediment from wine.
