Tape the paper onto the whiteboard provided

9. To understand the difference between chemical and physical changes
Objective- Again
To understand the difference between chemical and physical changes

11. States of Matter Solids = definite volume, definite shape
Liquids = definite volume, no definite shape
Gases = no definite volume, no definite shape

12. Law of Conservation of Matter: Matter cannot be created or destroyed
Laws of Matter
Law of Conservation of Matter: Matter cannot be created or destroyed
Law of Definite Proportions: a compound contains the same proportion of elements by mass

13. Physical Properties
Definition
Examples
Properties that can be observed or measured without changing the substance
Melting
Malleability
Solubility
Conductivity
Mass
Length
Color
Boiling point
Luster
Volume
Ductility

14. Chemical Properties
Definition
Examples
Properties observed when substances are chemically changing
Ability of a substance to chemically change
Rot
Decompose
React
Burn
Rust
Explode pH

15. Intensive Properties
Definition
Examples
Properties that do NOT depend on the amount of matter
Color
Chemical potential
Boiling point
Density

16. Extensive Properties Properties that do depend on the amount of matter
Definition
Examples
Properties that do depend on the amount of matter
Mass
Volume
Length
Particle number

17. Physical Changes Changes in size, shape, state, or appearance
Definition
Examples
Changes in size, shape, state, or appearance
Matter stays the same
Breaking
Bending
Cutting
Melting
Boiling

18. Chemical Changes Matter changes to a different kind of matter
Definition
Examples
Matter changes to a different kind of matter
Make something new
Rusting
Cooking
Burning
Reacting
**Indicators: Color change, gas formation, precipitation formation, temperature change

Why do leaves change color

22. Homework
Create 2 Posters (1 for chemical change and 1 for physical change)
Can use computer or draw on an 8 ½ x 11 sheet of paper
Must include
What type of change it is (chemical or physical)
What is happening (example: iron rusting)
Picture (or multiple pictures)
Explanation of why you categorized it as a chemical or physical change
Name and period ON THE BACK
NOTE: These are to be nice since I want to hang them up in the room!!! 
