Preview - Pnom - Particulate Nature Of Matter

Exploration 1- Experiment and Observations

  1. Press SETUP, and then GO/PAUSE/ADD ELEMENTS to run the model.
  2. Be sure to set the "gravity-on?" and/or "use-graph-for-gravity" switches to "on."
  3. To change the forces on the particles, click the DRAW GRAVITY VS HEIGHT GRAPH button and then draw a new graph by clicking and dragging in the graph side of the view.
  4. Experiment with different graphs to see how particles behave. For example, think about whether or not gravity is the same throughout the container.
  5. Once you've made a graph you're happy with, use the "SAVE" button to save to your machine so that the rest of your classmates can see it.

 

While conducting the experiment described in the previous steps, answer the questions below:

Questions

Please answer the questions below.

1.  Record the observations you made during the virtual experiment.

2.  How did the movement of the particles in this model compare to the movement of particles in previous activities?

3.  How did the graph you drew of gravity compare to the graph made by your classmates?

4.  Did the graph you made cause the particles to act like a liquid?
