What are the controlled variables within this experiment & what would happen if you didn't control this variab

Question

1. Test subject will be sat down in the biology lab a laptop. This would have already had the program NoLimitsSimulator downloaded within it.

2. The test subject will then be given an information sheet to fill out accordingly.

3. At this time, he/she will be asked if they have any questions about the experiment and will be answered accordingly by the experiment instructor.

3. The individuals’ heart rate will be taken in a silent manner and written down on data sheet, making sure that it is exact as possible.

4. The roller coaster simulation will play full screen on the laptop making it as realistic as possible.

5. After the simulation is done playing, the heart rate will be taken again recording this information on the original data sheet.

6. The experiment instructor will then take notice of the individual’s information sheet and compare it, out loud, to the heart rate taken and be asked further questions reflecting on the experiment.

Answer 1

You should have another volunteer watching for the same amount of time, a lame video of say-- a car rolling in a deserted highway, and compare the pulse variation on both. Even better, have a real guy going through a real roller coaster, and determine how much the simulation approaches an actual experience.
