How do cups made from materials with air in them minimize energy transfer?
- Do Now– Copy down today’s homework assignment in your planner. Open your ISN and add to the Table of Contents- “Air vs Liquid Test” p.40 (Left Side). Head p.40 properly with “Air vs Liquid Test- 12/20/18.″
- Turn and Talk– Last time we examined materials closely and found some interesting patterns that could help us explain why certain materials are better than others at keeping the drink cold. What was the pattern we observed about the materials that performed best? What was the pattern we observed about the materials that performed the worst?
- Demonstration- Air vs Liquid Test– Set up ISN p.40 with the question “How do cups made from materials with air in them minimize energy transfer? Draw the demonstration setup and data table. Record temperature in data table every minute for 5 minutes. Work with your partner to develop an initial explanation for the differences in the data. Write the initial explanation in the space below your data table on ISN p.40.

- Individual Model– Remember: the purpose of building an individual model is to gather your initial thinking. Imagine putting the cup of very cold water into something solid at room temperature. Then imagine putting it into a liquid at room temperature. Then imagine keeping it in the room temperature air (gas). Your models need to zoom in to show energy transfer through particle collisions in each of those three examples. Draw your models on the Lesson 7 Student handout.
- Notebook Work– Tape the Section B/C/D handout as flip page to ISN p.36. Tape the Lesson 7: Student Handout as flip page to ISN p.40.
