4. Today… We are going over physical and chemical changes
Your learning target today is:
I can look at a substance, or scenario, and will be able to determine if a chemical or physical change is occurring.
The Cornell notes should be taped/glued onto page 25 in IAN.

5. Why does this Matter? Has mass and takes up space
Everything around us is matter

6. What’s the Difference? Matter can change
Examples: Freeze, cut, burn, etc.
2 types of changes

7. Physical Changes
Definition: when the state or form of matter is changed without changing its chemical composition.
Examples: cutting, freezing, melting, etc.

8. Changes in State: Vocabulary

9. Chemical Change
Definition: takes place on a molecular level and produces a new chemical substance.
A chemical change always involves a chemical reaction.

10. Where is the Evidence??? Evidence of a chemical change:
color change, gas production, and release of heat, light, odor, or sound.
Examples: Burning (combustion), rusting, tarnishing and fermenting

11. Name That Change!! Talk over scenario with your table partner(s)

Good Luck!

27. For the rest of class…
You should be working on Physical and chemical changes worksheet
This should be taped/glued onto page 28 in IAN.
If this is not completed in class then it will be for homework.
Remember, we have a test on Friday…we need to be reviewing daily for this.
