Lesson Question

Where does the energy come from when a cold drink warms up?

Lesson Tasks

  1. Do Now– Get out your ISN and add to the Table of Contents- “Class Data” p.32 (Left Side). Head p.32 properly with “Class Data-11/19/18.″
  2. Class Data Table– Calculate the change in temperature of hot water, cold water, and room temperature water in each cup. Share your data on the class chart and average data for groups testing similar cups.
  3. Scientists’ Circle- Bring your ISN to Scientists’ Circle. Do we have enough evidence to answer this question: Where does the energy come from when a cold drink warms up? What evidence do we have from this investigation to help us answer the question?
  4. Model Tracker– What new idea can we add to the Model Tracker? How do particles transfer energy? Which particle loses energy and which gains energy? Add to the Model Tracker on ISN pages 18-19 (or continue to pages 20-21).
  5. Summary– Use your new insights about particle collisions to discuss how energy is getting into the cup. Answer the following questions on ISNp.30: Using our new ideas about collisions, how is energy getting into the cup? Will energy always transfer into the cup? Can energy from the cup transfer out into the world this way, too? What evidence do you have from your experiences that energy can move out of the cup?
