- 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.
- Do Now– Get out the following handouts: Explain It with Atoms and Molecules #1-5, Take It Further #7 (HW), Simulation Data Table; Get out your science notebook and add to your Table of Contents- “Solid, Liquid, Gas Conclusion”-p.36 (Left Side) and “Solid, Liquid, Gas Simulation” -p.37 (Right Side); Open your notebook to page 36 and head it properly with “Solid, Liquid, Gas-PhET Conclusion-11/17/15” and to page 37 and head it properly with “Solid, Liquid, Gas-PhET Simulation-11/17/15.”
- Check HW– “Take It Further- Bridges”
- Demonstration– Ball and Ring– In pairs, answer questions 3-5 on “Demonstration”
- Molecular Model Animation– Look at the animation of the heating and cooling of a solid and draw a model of the atoms in the metal ball at room-temperature and after it has been heated
- Understanding Connections– Put the statement on the Understanding Connections pages p.28-29 of your science notebook
