We are now going to experiment with another version of the Virtual Syringe model, this time through manipulating a temperature graph instead of a force graph.

1. Set the MOUSE-INTERACTION chooser to anything that isn't "none - let particles move". 
2. Press SETUP, and then GO/STOP/ADD ELEMENTS to run the model.
3. Set the MOUSE-INTERACTION to “draw basic wall” or “draw red removable wall” or “draw blue removable wall”. Then add a wall to the bottom of the syringe so that its end is capped and the inside of the syringe is a closed system.
4. Set MOUSE-INTERACTION to “add green particles”. Add particles to both the outside and inside of the syringe. Set the MOUSE-INTERACTION chooser to "none - let particles move" and let the model run until it has reached equalibrium and looks similar to the picture to the right
5. Set MOUSE-INTERACTION to "choose heat/cool region" and then click a spot inside of the closed syringe chamber. This region should temporarily fill up with a brown color to show it has been selected.
6. Click "Draw Temp vs Time Graph," then click and drag in the graph area of the view to draw a graph that represents how the temperature of the air in the flask changed over time during the teacher's demo.
7. Press PREPARE FOR EXPERIMENTAL RUN and then press RUN EXPERIMENT to test the effects of the temperature graph on the model.
8. Once the experiment has run, use the "SAVE" button  to export your experiment.
