|11:41-1:01 (includes lunch as usual with usual times)||Period 2|
- Gases and liquids are made of molecules or inert atoms that are moving about relative to each other.
- In a liquid, the molecules are constantly in contact with others; in a gas, they are widely spaced except when they happen to collide. In a solid, atoms are closely spaced and may vibrate in position but do not change relative locations.
Periods 2 & 6 Learning Activities:
- Do Now– Get out your science notebook and open to page 32. In your cooperative table group, discuss the answer to the following questions: How is the motion of particles different in solids than in liquids? What keeps particles in liquids and solids close to one another?
- Review Comparison of Particles in Liquids & Solids
- Investigative Phenomenon–Why do bridges have flexible connections?– Using what you learned about the effect of temperature on the motion of atoms in a solid in the metal ball and ring demonstration, create a model to explain what is happening to the road on the bridge. (Write-Pair-Share). Trim and tape your model as a flip page to p.32.
- Driving Questions Summary Table– Complete the Summary Table on pages 26-27 for the Molecules in Solid Activity
Periods 3 & 7 Learning Activities:
- Do Now– Get out your science notebook and add to your Table of Contents- “Molecules in Gas-p.35” (Right Side). Open your notebook to page 35 and head it properly with “Molecules in Gas-Investigation-11/29/16.”
- Period 7- Complete Driving Questions Summary Table– Complete the Summary Table on pages 26-27 for the Molecules in Solid Activity
- Demonstration- Basketball and Compressed Air- How do these demonstrations show that gas is matter? Answer questions 1 & 2 on handout.
- Notebook- Set up page 35
- Investigation-Molecules in Gas- How do heating and cooling affect a gas? On page 35, determine a problem statement, hypothesis, and experimental variables for the key question. Read the Activity handout.
