1. EQ: Compare and contrast substances and mixtures.

2. * Anything that has mass and takes up space * In other words, it has both mass and volume * Everything you see and some things you cannot see, like air

3. * Space * Sound * Light * Forces * Energy

4. * Building block of matter * Made of protons (+), neutrons (o), and electrons (-) * Protons and neutrons in nucleus * Electrons in electron cloud

5. * Matter whose composition is always the same * Ex. Sugar is always C 6 H 12 O 6, water is always H 2 O, and oxygen is always O 2. * Two types: elements and compounds

6. * Substance made of just one type of atom * Exist individually, such as aluminum atoms, or in groups, such as pairs of oxygen atoms

7. * Substance with 2 or more different elements bonded together but always with the same formula * Formula: symbols and #s that represent compound *H2O*H2O * CO 2 * C 6 H 12 O 6 * Different properties than elements that make them up

8. * Matter that varies in composition * 2 or more substances blended together physically (therefore can be separated, like sand and water) * Two types: heterogenous and homogenous * Heterogenous: not evenly mixed * Two samples can have different amounts of substances (ex. 2 buckets of sand from the beach) * Homogenous: evenly mixed * Also called solution * Two samples will have same amounts of substances (ex. 2 bottles of Gatorade)

9. * Use the following 7 terms to create a graphic organizer showing how matter is classified. * Add at least one picture and at least one example to each. * Be sure to use COLOR on this page! * Matter ** Substances ** Elements ** Compounds * Mixtures ** Heterogenous ** Homogenous

10. * Use the following 7 terms to create a graphic organizer showing how matter is classified. * To assist you in this task, use figures 4 and 6 from chapter 6. * Be sure to use COLOR on this page! * Matter ** Substances ** Elements ** Compounds * Mixtures ** Heterogenous ** Homogenous
