TE 2.1: Visualizing Motion Energy

Objective: KWBAT explain the relationship between the speed of molecules and the amount of energy in a thing by investigating in the Sim.
Part 1: Do Now

Part 1: Do Now

1

Chapter 1: The temperature of an object is related to the kinetic energy of its molecules, which increases as the speed of the molecules increases.

Molecules move and change speed. Temperature is a measure of kinetic energy, which is the energy of the movement of the molecules. Hotter things are made up of faster-moving molecules, which have more kinetic energy. Colder things are made up of slower-moving molecules, which have less kinetic energy. Changes in temperature are the result of molecules changing kinetic energy.

Summarize this Chapter 1 Focus in your own words! 1-2 sentences.

Dear Mr. Chang,
I am worried about your proposal to install a groundwater heating system in my daughter’s school.
I don’t think that water at a temperature of 30 C has enough energy to heat the school. If the school is too cold, the students won’t be able to focus on learning.
Sincerely,
David Li

In the letter, Mr. Li mentions he is worried about the groundwater system not having enough energy to heat the school.

What do you think energy has to do with the heating systems?

0

When would you expect to have the most kinetic energy while riding a bicycle?

Part 2

Part 2: Video of Air & Water Demonstration

We saw that warm water molecules can heat up and speed up the molecules of cooler air. You will now use the Thermal Energy Simulation to learn more about kinetic energy and how it affects the speed of molecules.

0

Describe TWO observations from this video related to temperature!

Sentence Starter:
One observation I had is....
Another observation...

0

Predict: What do you think would happen if we let the experiment keep running?

1

Based on what you learned in Chapter 1, what can you conclude happened to the molecules in the air as they got warmer?

Part 3: Visualizing Motion as Energy


Part 3A: Explore How to Change Kinetic Energy in the SIM

Open the Thermal Energy Simulation and complete the following steps:
  • Add 1 sample of any size
  • Turn on “View Kinetic Energy”.
  • Explore different ways to change the kinetic energy of your sample.
2

In the SIM, how can you change the kinetic energy of a sample?

1

In the SIM, The more yellow an object is, the more kinetic energy it has.

1

The less yellow an object is, the more kinetic energy it has.

Part 3B: Speed of Molecules and Kinetic Energy

Start over by resetting the Simulation, and then complete the following steps:
  • Add two samples.
  • Do NOT turn on the “View Kinetic Energy”
  • Make one sample have faster molecules.
  • STOP here to make a prediction in the next question below
0

Predict:

I predict that the warmer sample with faster molecules will
have __________ kinetic energy than the colder sample with slower molecules.


Part 3C: Return to the SIM and complete the following steps:

  • Turn on the View Kinetic Energy
  • Observe both samples and the different amounts of kinetic energy.
  • Check your prediction.
1

I observed that the warmer sample with faster molecules had _______ kinetic energy than the colder sample with slower molecules.

1

Describe the kinetic energy of the slower sample.

Hint: I am looking for the MOVEMENT of the molecules.

Sentence starter:
The kinetic energy of the slower sample was...
