Learning Question

How does energy transfer into a cold drink when it warms up?

Learning Tasks

  1. Do Now– Get out your ISN and open to pages 18-21. Try to solve the word picture puzzle.
  2. Scientists’ Circle– When we decided to look at the drink warming up, what new things did we figure out about how this happens? Support your new ideas with evidence from class investigations and simulations. Look back in your scientist’s notebook! Summarize the big questions we’ve been working on and pose the question “How does energy transfer into a cold drink when it warms up?” Remember that we have data on how energy transfers between the water in the cup and the air outside of the cup. Analyze the class data by sharing what you notice about patterns in the data and what they might mean. What do you notice when the hot water was inside the cup? What do you notice when the cold water was inside the cup? What do you notice when the room temperature water was inside the cup? For each instance, what was the KE of the particles like at the beginning compared to the end and where did the energy go? When energy was moving between two substances? When was energy not moving? Why does the energy not move when the temperatures are the same? How do you know this? Which way did energy flow when there was a temperature difference? How do you know? How does our class data support our claims? Can energy ever flow from something cold to something hot?
  3. Model Tracker– What have we figured out that helps us answer the question “How does energy transfer into a cold drink when it warms up? What rule about the direction of energy flow did we figure out? Add to the Model Tracker on ISN pages 18-19 (or continue to pages 20-21).
