1. Launch: 1/4
 Grab your binder and immediately take a seat!
 On the folder, write your
 first name
 last name
 block #
 Carefully empty the contents of binder into the folder
 Make sure it stays organized!
 Objective: I can describe the properties of the three
states of matter

2. New Changes for the New Year!
 Late homework policy
 Late homework in now due the day after you return
 It is your responsibility to get it stamped the day after
you return, or no credit!
 Notes packets, handouts, and practice questions will
can be found:
 online (lpschem.wordpress.com)
 at the back of the classroom
 You are still responsible for taking notes!
 Absent students will be omitted from class points

3. New Changes for the New Year!
 Class consequences
1. Name on board stay outside
2. Take a break within 5 feet of
the door until
3. Call home called in by Mr.
4. Sent to Mr. Wandera Heffner

4. Same Old, Same Old
 Class rules
 PAT Time
 Big Goal!

5. What are the 3 states of
matter?
Mr. Heffner
1/4/10

6. What are the 3 states of matter?
 Molecules want to bounce around randomly
 But, attraction between molecules can sometimes
make them stick together
 inter = between
intermolecular
attraction

7. What are the 3 states of matter?
 Because of intermolecular attraction, matter can
exist in 3 different states
Solid Liquid Gas

8. What are the properties of gases?
 Gases:
 No intermolecular attractions
 Random movement
 Really fast!
 Example: steam
Gas

9. What are the properties of liquids?
 Liquids:
 Weak intermolecular attractions
 Random movement
 Slow
 Example: water
Liquid

10. What are the properties of solids?
 Solids:
 Strong intermolecular attractions
 Molecules stuck in ordered arrangement
 Don’t move
 Example: ice
Solid

11. Oobleck!
 Work in a group of four
 Take turns playing with the Oobleck
 As a group discuss: Is Oobleck a solid, a liquid, or
a gas?
 Have recorder take out a half sheet of paper
 Write names
 In 3-4 sentences, answer the discussion question.
 Your answer should include and explanation of why your
group came to that decision
 Be sure to get feedback from all group members

12. Oobleck!
 Oobleck is…
 a non-Newtonian liquid
