How does energy transfer into a cold drink when it warms up?
- Do Now– Copy down today’s homework assignment in your planner. Open your ISN and add to the Table of Contents- “Revised Model” p.34 (Left Side). Head p.34 properly with “Revised Model-11/27/18.″
- Turn and Talk- Open your ISN to page 32. Look at the class data table- The data table supports our ideas about energy flow from hot to cold when there is a temperature difference between inside the cup and outside. But is this true in the same way for all of the cups that we tested?
- Model– It sounds like we know something is happening with particles colliding to transfer energy from warm air outside cup to cold water inside cup. Let’s make a diagram to make sure we agree on how this is happening. Look at your own initial model on ISN p.16. Now turn to ISN p.34 and create a revised model to explain how energy got inside the cups. Present your individual model to your Cold Cup Design Challenge group and now as a group, complete the model of how you now think the drink in the cup is warming up.
