Where does the energy come from when a cold drink warms up?
- Do Now– Get out your ISN and open to p.31. Turn & Talk: What did the collisions game with the coins tell you about how energy is transferred?
- Collisions Game– This game modeled how particles bumping into each other may transfer energy. Answer the questions on ISN p.31, complete the Analogy Map handout, and tape the Analogy Map handout as a flip page to ISN p.31.
- Summary– Use your new insights about particle collisions to discuss how energy is getting into the cup. Answer the following questions on : 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?
