- 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 3, 4, & 7 Learning Activities:
- New Seats!
- 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 2 & 6 Learning Activities:
- New Seats!
- Do Now– Get out your science notebook and add to your Table of Contents- “Molecules in Solid- p.32” (Left Side). Open your notebook to page 32 and head it properly with “Molecules in Solid-Model & Conclusion-11/22/16.” Get out your Demonstration handout with questions 3-5. Trim and tape Demonstration questions 3-5 as a flip page to page 33.
- Notebook– Review Demonstration Questions 3-5. Set up page 32.
- Model & Conclusion- On page 32 of your science notebook, draw a model of the atoms in the metal ball at room temperature and after it has been heated based on your observations of the metal ball and ring. Make a conclusion about whether heating or cooling affects the atoms in a solid and use your observations as support. Observe animation of heating and cooling a solid to adjust your model & conclusions.
