Modeling Energy in the GL System Preview CT-STEM

Initial Observations of the Model

Please answer the questions below.

Question 2.1

Click "setup".

Then click "go".

We are going to make some initial observations, so don't change any of the sliders yet.

List at least 3 observations of what you see happening in the model.

Question 2.2

Let the model continue to run. Be sure the graphs go to at least 1500.

What do you notice about the top graph? What is happening with the 2 phases of matter over time?

Question 2.3

What do you notice about the average temperature graph over time?

Question 2.4

Directions:
Click trace, so the box is checked.
Click “Observe liquid molecule”
Analyze the graph “temperature of the observed”

What do you notice on the graph when the molecule is a liquid?

Question 2.5

What happens to the temperature when the molecule becomes a gas?

Question 2.6

What happens to the temperature while the molecule is a gas?

Question 2.7

What happens to the temperature when the molecule changes back to a liquid?

These notes will appear on every page in this lesson so feel free to put anything here you'd like to keep track of.
