- 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, 4, & 6 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.”
- Periods 4 & 6- 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.
Remember: As long as you act like a scientist when we do science, you will be treated like a scientist and conduct investigations. If not, you get to watch the rest of us do science.
Periods 3 & 7 Learning Activities:
- Do Now– Get out your science notebook and open your notebook to page 35.
- Investigation- Molecules in Gas- How do heating and cooling affect a gas? Read procedure and model steps. Review Science Safety Regulations and complete Lab Safety Checklist- Before You Begin. Review Table Group Member Responsibilities. Begin Lab! Record observations by sketching on bottom of handout. Complete Lab Questions 4 & 5 and Lab Safety Checklist– After Lab is Completed. Tape Activity handout as flip page to p.35.
