1. Matter is anything that occupies space and has mass.
2. A Mixture is a physical combination of two or more substances where there is no chemical combination or reaction.
3. A Solution is a uniform mixture of a solute (usually a solid) dissolved in a solvent (usually a liquid). When you stir a spoonful of sugar into a glass of water, you are forming a solution. This type of liquid solution is composed of a solid solute, which is the sugar, and a liquid solvent, which is the water.
4. Decantation is a technique used in separating a less- dense substance from a denser one.
5. Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the water passes through the filter paper (it becomes the filtrate).
6. Sieving is Involves using a strainer or a big screen to separate the components of solid mixtures.
7. Evaporation is a solid remains unaffected on heating the mixture up to the boiling point of the liquid. In this method, the solid soluble component of the mixture is separated from a liquid.
8. One way of separating the nails from the sand is to use a Magnetism. This works because the nails and sand have different properties, or features. The nails are made from a substance that is attracted to magnets, but the sand is not attracted to magnets.
9. A Heterogeneous Mixture is a mixture having a non-uniform composition throughout the mixture.
10. A Homogeneous Mixture is a mixture in which the composition is uniform throughout the mixture. All solutions would be considered homogeneous.
