6. Introduction to Matter
-What is matter?
-Is anything not considered matter?
-What are the three forms of matter?

7. Modeling the three phases
Liquid
Gas
Solid

8. You will assigned a phase of matter:
As a group you will have to
-Model it
-Explain the key details associated with that phase of matter
You will have 10 minutes, then you will have to present it

9. Phases of Matter
-What differentiates the different forms of matter?
-What are the key characteristics?
-How can we tell which is which?

10. Solid, Liquid, Gas -Shape -Compressibility -Volume

11. Physical Changes:
-Reversible
-Alter matter but composition stays the same
Physical Properties:
-Observable qualities

12. Chemical Property:
-What occurs during a chemical reaction
-Help ID unknown substances
Chemical Change:
-Cannot be undone
-When reactants go through a reaction it is the
end result

13. Physical or chemical property
