2 On the first day of Science, Ms. Kisner gave to me…

3 One Independent variable
IV=cause DV=effect

4 Two Electromagnets!

5 3 states of matter

6 4 reactive groups Groups 1,2,16,17

7 Melting, freezing, evaporation/boiling, condensation, dissolving
5 physical changes Melting, freezing, evaporation/boiling, condensation, dissolving

8 Law of conservation of mass Reactants -> Products
6 chemical equations Law of conservation of mass Reactants -> Products

9 7 signs a chemical Gas produced, solid produced, color change, odor change, change in temperature, sound given off, light given off

10 NOBLE GASES= unreactive due to full outer shell
8 valence electrons NOBLE GASES= unreactive due to full outer shell

11 IN ALL CHEMICAL CHANGES
9 chemical bonds IN ALL CHEMICAL CHANGES

12 10 mixtures keeping Mixtures physically combine and separate
Their components KEEP their PROPERTIES

13 11 compounds losing Compounds are combined and separated through chemical changes The components LOSE their properties

14 Graduated cylinder, triple beam balance, spring scale
12 tools and units Graduated cylinder, triple beam balance, spring scale
