In this last step, you will modify the code of the sensors to identify patterns in your model.
- Load your saved world, using one of the LOAD button at the bottom left of the sandbox window.
- Change the sensor code from the windows CODE 1, CODE 2, CODE 3, and CODE 4 to create the type of sensor behavior(s) you want.
- Press GO/PAUSE/ADD ELEMENTS to run the model.
- Set the MOUSE-INTERACTION chooser to add/move sensors. And add sensors or move the ones you have added using your mouse.
- While you are working you may choose to save your world periodically using the SAVE button so that you do not risk losing your progress .
Note: Do not change the code of the EXAMPLE 1, EXAMPLE 2, EXAMPLE 3, or EXAMPLE 4 windows. These codes are provided to you so that you can copy them and paste them to the code windows in case you want to reset the code of a sensor or try a new code.
Next, test your model to see how the particles move in it by turning the MOUSE-INTERACTION chooser to "none - let particles move"
- Record the results in the following questions. Because some particle interactions involve randomness, it's important that you run your experiment more than one times.
- When you've collected your data, you may want to average some measurement values that changed over the course of many runs. For example, if you ran the model three times with the same starting conditions, you might want to average the value of your dependent variable (pressure, time, etc) over those runs.
Repeat any of these steps until the sensor data either:
- helps you discover interesting patterns in the data.
- provides you additional evidence for your scientific explanation from the previous activity.
- helps you understand important mechanisms at work that explain cause some (or all) of the patterns in the data.
Record the relevant data from the model run that you intend to use in the following step.
If you want to use the world you have set up or changed in this step with more sensors in the next step, save your world for future usage.
