7. Elements and Matter What is matter?

8. All living and non-living things can be broken down into different elements. Elements:

10. Periodic Table Activity Get a red, blue, and green colored pencil Make a key at the bottom of the paper with the 3 colors. For the following elements shade in the chemical symbol RED, the atomic number BLUE, and the atomic mass GREEN Oxygen, Carbon, Nitrogen, Hydrogen, Calcium, Phosphorus

11. Each element has. Ex: Oxygen Colorless Odorless gas

12. Elements in the body List in notebook: Oxygen – Carbon – Hydrogen – Nitrogen – Calcium – Phosphorus – 19 others

14. Compound: atoms of 2 or more elements joined together by chemical bonds. Ex: H 2 O (has both elements hydrogen and oxygen in it)

15. Atoms Atom:

16. Atoms are the building blocks of matter Contain 3 parts + -

17. Chemical Reactions Why do we need chemical reactions? Chemical Reactions: Broken bonds  Formed bonds 

18. ACTIVITY Baking soda + Vinegar 2 Chemical Reactions 1. HC2H3O2 + NaHCO3  NaC2H3O2 + H2CO3 2. H2CO3  H2O + CO2 OR Mentos in Soda! = LOTS OF BUBBLES (carbon dioxide) LETS WATCH!
