Learning Question

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

Learning Tasks

  1. Do Now– Copy down today’s homework assignment in your planner. Open your ISN and add to the Table of Contents- “Touching Hot & Cold” p.37 (Right Side). Head p.37 properly with “Touching Hot & Cold-11/29/18.″
  2. Consensus Model– Observe individual student scientists’ models in Google slides. What do you notice that is similar across all models? Is there anything that you think is different about your model? We’re going to take stock of the ideas in everyone’s models to build a class consensus model that everyone agrees upon and that explains what happens to cause a drink to warm up inside a cup. Remind students of class norms for productive scientific discussions and refer to the Communicating in Scientific Ways on ISN p.14. As student scientists offer proposals, create a public representation of the consensus model on chart paper. Agree on how we should represent cold and hot, particle motion, temperature as average kinetic energy, etc.
  3. Scientific Language Key Term– Introduce key term- conduction. Add definition below model on ISN p.34- “Heating that happens when two things of different temperatures touch and the particles with more energy collide with particles with less energy and transfer their movement.” Add the key term conduction to Index.
  4. Brain Break– Optical illusions
  5. 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.
