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 page 34. Read the definition of conduction. Now turn to your partner and give an example of conduction by touching something and it feels hot or cold.
  2. Scientists’ Circle– What have we figured out that will help us answer the unit question- “How can we design a cup to keep a drink cold?” Look back at the questions posted on the Driving Question Board (DQB). What questions can we answer now? Remove a notecard of a question that has been addressed. How was the question addressed? What are we still wondering about the cold drink warming up in the cup? What else do we need to know in order to complete our design challenge? Add any new question to the DQB.
  3. Modeling Hot and Cold– What are some examples of conduction from our own experiences? Think about times you’ve touched something and it feels hot or it feels cold. When you touch something and it feels hot or it feels cold, the particles from the object and the particles of your hand are colliding. What can we say about conduction when something feels hot? How is it different when something feels cold? Let’s model these ideas! On ISN p.37, draw two models to help explain what is happening to your hands to experience hot or cold. Draw a diagram on the top half for what is happening on a particle scale when you touch something hot like a pot from the stove. Share your model with your partner and then revise, if necessary. Then draw a diagram on the bottom half for what is happening on a particle scale when you touch something cold like an ice cube. Share your mode with your partner then revise.
