- 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 your Lab Safety Checklist and complete questions 1-5 in the section After Lab is Completed. Get out your science notebook and add to your Table of Contents- “Molecules in Motion- p.30” (Left Side). Open your notebook to page 30 and head it properly with “Molecules in Motion-Model & Conclusions-11/16/16.
- Notebook– Set up page 30.
- Review HW- Watch the video of food coloring in hot and cold water. Modify sketch of observations. Review Lab Question #1-4. Tape the Activity handout as a flip page to page 31.
- Model & Conclusion- On page 30 of your science notebook, draw a model of water molecules in cold, room temperature, and hot water based on your observations of the investigation of food coloring in hot and cold water. Make a conclusion about whether the speed of molecules in hot water is different than in cold water and use your observations as support. Observe animation of heating and cooling a liquid to adjust your model & conclusions.
