What are the Controlled Variables within this experiment and what would happen if you didn't control this vari

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

The control is the heart rate taken before the simulation, and you need it because without it, you couldn't tell whether or not the simulation had any effect on the test subject's heart rate.
