The purpose of the experiment in part B is to maintain a control for the other experiments that would take place to the pillbugs. If it weren’t for this experiment there would be nothing to compare our experiments to the pillbugs to. I expected the numbers to be random since I wasn’t testing anything, I was just observing how they reacted to the light and the new environment. Since there wasn’t anything being tested I figured that the pillbugs would just be curious about the new environment that they were in, this new environment is what I believe caused their movement to be random. This randomness is what made my control and made it easy to compare it to the other data that was collected. After testing my hypothesis in part C, I found out that my conclusions did agree with my hypothesis. I had hypothesized that the pill bug would be drawn towards the dark since its natural environment is in the...
