6. 2. What is matter made of? Elements Pure substances that can’t be broken down oxygen = O 2 table salt, sugar Compounds Pure substance made of 2 or more elements Carbon + 2 Oxygen = Carbon Dioxide CO 2 Hydrogen + Oxygen = H 2 O A. PURE SUBSTANCES: 1 kind of matter

7. What is matter made of? B. NOT A PURE SUBSTANCE Mixtures - 2 or more substances mixed together not chemically combined Substances keep their properties Solutions are the “best-mixed” mixture

8. Changes in Matter Physical change: alters the form, but not its identity Chemical change: a substance that changes or combines to form a new substance Chemical activity: the ability of a substance to change

9. Testing your knowledge…. In the photos, can you tell which is an element, compound, or mixture. Review: An element contains just one type of atom. A compound contains two or more different atoms joined together. A mixture contains two or more different substances that are only physically joined together, not chemically. A mixture can contain both elements and compounds.
