TE 2.2/TE 2.3 Visualizing Energy and Evaluating Claims

Objective:

KWBAT gather evidence from the Sim and the article “How Air Conditioners Make Cities Hotter” in order to choose between two claims about why molecules change speed.

Untitled Section

Part 1: Warm Up

Last time, we explored kinetic energy in the SIM and how it relates to the speed of molecules of a thing. Below are three different diagrams representing the molecules of three pairs of samples. Use your knowledge of how temperature, speed, and kinetic energy are related to help you complete the Warm Up.

Describe how energy in the molecules of hot soup would change if you left and came back later to find that the soup was now cold. Use the vocabulary below.


  • speed of molecules
  • kinetic energy
  • more / less
  • temperature
  • slower / faster
  • average kinetic energy
Sentence starters:
When the soup was hot, the energy of the molecules…. The molecules changed because...

Part 2

Part 2: Considering Claims

Claim 1: Molecules speed up when energy is created and slow down when energy is destroyed.

Claim 2: Molecules speed up when they get energy from other molecules, and slow down when they give energy to other molecules.

Part 4: Simulating Temperature Change

In this activity we will continue to gather evidence from the SIM but this time we will use a new feature. You will drag two the samples together so they become in contact with each other.

Reset the Thermal Energy SIM and complete the following steps.
  • Add TWO samples of the same size.
  • Turn on “View Kinetic Energy” and “View Energy Transfer”.
  • Press the + or - buttons to add or remove energy so that one sample is warmer than the other.
Click and drag one sample to the other so they are now touching. It should look similar to this:


  • Click “Analyze” and observe what happens.
  • Complete questions 2-3.
