1. Activity 56: Shake the Shot
Activity Overview:
In this activity you will further investigate energy transfer and transformation. You will add kinetic energy to a system and explore the resulting energy transformation. The investigation introduces the relationships between motion, temperature, and thermal energy.

2. Activity 56: Shake the Shot
Key Vocabulary Terms
Energy Transformation
Heat
Kinetic Energy
Temperature
Thermal Energy

3. Heat What is Heat? Energy in Transit Hot  Cold Heat is a Process
Thermal Energy = Noun

4. Temperature Measurement How do you read a thermometer?
of the average energy per molecule of a substance.
How do you read a thermometer?

5. Read pg. D-19
Which has more thermal energy? Explain.

6. Activity 56 Title: Shake the Shot
Problem: How can kinetic energy be transformed into another energy type?
Initial Thoughts:

7. Read Materials
Read Procedure
What Variables do we need to control?
Shaking Style (up/down vs. swirl vs. side-to-side)
Hold on Vial
Temperature Reading Position

8. Changes to procedure:
Keep the cap with the hole for the thermometer on the vial and put your thumb or finger over the hole while you shake the shot.
Each group will only do one trial
Compare you results with the other 3 groups on your side of the room. Use the 3 closest pieces of data (remove the outlier). Record the data and find the average temperature.

9. Follow-up
There is a direct relationship between the amount of kinetic energy put into a system and the increase in temperature of that system.
It is reasonable to infer that the kinetic energy put into the system resulted in more energy transformation.

10. For each time interval, why did we perform three trials and then average the temperatures?
Describe any possible sources of error in your experiment, and explain how each may have affected your results.
Use evidence gathered in this investigation to describe the relationship between:
Shaking time and temperature change
Shaking time and energy transfer

11. Of the two descriptions below which, a or b, correctly describes the transformation of energy shown in the diagrams below? Explain your choice.
Potential energy  temperature
Kinetic energy  thermal energy
