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

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

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

Same Old, Same Old Class rules
PAT Time
Big Goal!

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

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

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

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

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

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

Oobleck! Oobleck is…
a non-Newtonian liquid
