1. Classification of Matter

2. Matter Has mass Takes up space Everything is made up of it

3. Substance Same chemical composition; pure. They stay the same all the way through; they are made up of elements and compounds Elements- pure substances that are made up of one type of atom; atoms are the smallest part in an elements Compounds- are 2 or more elements that are chemically bound; molecules are the smallest piece of a compound

4. Mixture When two or more things are physically put together They can be.. homogeneous (solution)- they are the same through out, when something dissolves into something ex: Kool Aid, lemonade Heterogeneous- they have compositions that vary ex: cereal and milk

5. Heterogeneous Are made up of suspensions and colloids Suspension- are particles that are big enough to be seen and they settle out Colloid- are in a gel, foam, or cream form. The particles do not settle but they are larger than the solution
