1. Molecular Dance Party HOW would you dance to THIS SONG?
Now HOW would you dance to this song?
Which song do you think represents high kinetic energy?
Therefore, which songs do you think represents hot and cold molecules?

2. Matter with more Thermal Energy also has more Kinetic Energy.
What we learned
Matter with more Thermal Energy also has more Kinetic Energy.
In other words, the hotter it is the faster the molecules move.

3. When I leave a metal spoon in a pot of hot water the spoon gets super hot.
How does this happen?
What is happening at a molecular level?

4. Molecular Dance Party Continued
Now lets think about how the Thermal and Kinetic Energy is TRANSFERRED?
How is heat being transferred from one calorimeter to the other?
How could our class dance party relate to the transfer of kinetic energy in the calorimeter lab?

6. What direction is the energy flowing?

7. Molecular Movement in Heat Transfer
If a bowling ball that is traveling slowly is hit from behind by a bowling ball that is moving fast, what happens to the slow ball? What happens to the fast ball? starts moving faster, starts moving slower, stays at the same speed
The slow ball__________________________.
The fast ball___________________________.
If we replace the bowling balls with molecules, this example helps us visualize thermal energy transfer, or how energy from hot objects can affect the energy in cold objects and vice versa.

8. Create a Group Model
With your group create an initial model of what was going on in the calorimeters on a molecular scale as time went on.
How is energy being transferred? (write question on top)
Models always include:
Drawings
Labels
Description
NO Color (pencil only)

9. Effective Feedback Each person gets two sticky notes
Look at every poster
Choose two that you would like to put constructive comments on
Effective Feedback
SPECIFIC
POSITIVE
PURPOSEFUL
HELPFUL

10. Adjust Initial Models Read the feedback each student gave your group.
Use the information that your peers gave you adjust your initial model.
Be prepared to share with the class your improvements.

11. In the calorimeter lab:
Where is the energy coming from when the temperature increases?
Where is the energy going when the temperature decreases?
How is the energy moving through the metal bar?
Can molecules with less kinetic energy transfer energy to molecules with more kinetic energy?
Adjust your model to illustrate any new ideas.

12. Class Discussion
What sort of feedback did you receive that was particularly helpful?
What sort of information was your initial model missing?
What did your model have that you think every model should have?
