Core Ideas:

  • 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.

Learning Activities:

  1. Do Now– Get out your science notebook and add to your Table of Contents- “Molecules in Solid- p.33” (Right Side). Open your notebook to page 33 and head it properly with “Molecules in Solid-Demonstration-11/21/16.” Discuss with your group the following questions: What do you know about molecules in a liquid? How does heating or cooling affect the speed of the molecules and the distance between them? Do you think what you learned about molecules in a liquid would be the same as or different than the particles in a solid?
  2. Complete Driving Questions Summary Table (Period 3)– Complete the Summary Table on pages 26-27 for the Molecules in Motion Activity
  3. Notebook- Set up page 33.
  4. Demonstration– How does heating and cooling affect the atoms in a solid? On page 33, determine a problem statement, hypothesis, and experimental variables for the key question. (Write- Pair- Share). Observe the ball and ring demonstration and answer questions 3-5 on the Demonstration handout.
