Conclusion: This experiment shows that pill bugs perfer a wet environment over a dry environment. Our data showed that when there are two different environments right next to eachother, a wet one and a dry one, the pill bugs will go to the wet environment. By looking at our data, we noticed that every time we gave the bugs the option of a wet environment and a dry environment, atleast 5 out of 6 bugs would pick the wet environment. This data supports our hypothesis, which was, If we place a wet paper towel in one circle, and a dry paper towel in the other, then the pill bugs will go to the circle with the wet paper towel

CONCLUSION:
In this experiment, our data showed that pill bugs chose to inhabit the dry soil chamber increasingly as time went on. We found that at first, when we were setting up the control experiment, there were more pill bugs in one side than in the other chamber. Our control experiment included dry soil of the same quality in both chambers. When water was added at the end of the first 5 minute interval, our group noticed that the pill bugs evened out into 3 in each chamber. Already the pill bugs were starting to move into the dry chamber instead of the moist one. As time went on, all the pill bugs, except for one (who was immobile) moved into the dry soil environment. This data does not support our hypothesis. We had previously thought that if the environment in one chamber was more moist than the other, then the pill bugs would choose to inhabit that chamber. Instead, we found that pill bugs did not move into the moist conditions; they inhabited the dry soil chamber.
We also think that our expriment was inconclusive because according to PestWorld For Kids, pill bugs live in moist conditions. Therefore, our data and conclusions contradict the widely known fact that pill bugs would have chosen the wet environment. There are many reasons that our data could have been flawed. One of these reasons might have been because there was another variable that we did not know of that was interfering with the experiment. Another could have been because we put the dirt while the pill bugs were still in the chambers: this could have caused the confusion of the pill bugs in their navigating. The third reason might have been because we added too much water to the chosen chamber. This could affect the pill bugs by not being used to these certain conditions. To improve this experiment, we would use a different tray with 3 chambers. One chamber would be empty, and would be where we would place the pill bugs at the beginning of the experiment. Once all the pill bugs have left the chamber, we would close it, and allow them to wander around the other two chambers that contain the same amount of dirt, with one of them containing water. This would eliminate the possibility of being buried by the dirt and not being able to move.

Conclusion:
In this experiment it appears that the Pill Bugs prefer a moist enviornment as opposed to a dry one. We hypothesized that the pill bugs would chose to be in a comfortable wet habitat as opposed to a dry one. At the beginning of our experiment, the pill bugs gravitated towards the right tray during the Control Experiment. The first time, they appeared to have no preference to either side. However, when we put the wet paper towel in, it became quite clear during the first five minutes as to whether they prefer a wet or dry environment. It seemed as though within the first minute, they crawled over to the wet side. Some crawled underneath the paper towel, indicating that it's possible that they prefer a darker environment as well. While comparing the control group to the pill bugs exposed to the wet paper towel, we concluded that they do, in fact, prefer the more moist environment. We observed the behavior of the pill bugs every two minutes and counted the number of bugs in each tray. At most times throughout the experiment, we saw that once they pill bugs discovered the side of the tray with the moist paper towel, they stayed there; further supporting our hypothesis. By creating a control group, we could come to the conclusion that the pill bugs would move as they pleased and did not prerfer one side to the other. According to www.pestworldforkids.org, "Pill bugs live in wet locations. They are found under damp objects or in organic garbage. If pill bugs enter a building, they will often dry out and die." This information supports our original hypothesis and reassures the data that we collected.

Conclusion: In this lab, we discovered that the pill bugs preferred a wet environment to a dry environment. Our data supports this discovery because during each test, the number of pill bugs that ended up in the wet environment after 3 minutes was 4 or 5, and the number of pill bugs that ended up in the dry environment was 1 or 2. This does support our hypothesis: If a wet paper towel is put in one side of the container, and a dry paper towel is put in the other, the pill bugs will most likely go to the side with the wet paper towel. This has also been proven true, that pill bugs prefer a wet environment to a dry one, on PestWorldForKids.org, they also state that pill bugs prefer a wet environment because they will dry up and die if they are put inside a dry building.
We also did another test, where we changed the independent variable: the environment. We took all of the paper towels out of the container and just left it as is. We still tracked the number of pill bugs that went to which side, and timed it for 3 minutes. The result was that the number of pill bugs on each side of the empty container after 3 minutes was mostly the same, with 3 on each side.
If we were to do these experiments again, we could do a few different things. We could switch the sides of the wet paper towel and the dry paper towel; change the time from 3 minutes to 10 minutes; alter the temperature of the room; and alter the light in the room.

Through our data we have concluded that our hypothesis, which was if the pill bugs prefer dark spaces as opposed to light spaces, is correct. We knew this because 66% of the time the pill bugs preferred the dark space rather than the light space. To make this test better we could have had longer time intervals which would make the results more accurate. Our data allows us to conclude that pill bugs do, in fact, prefer the dark.

Conclusion:
In this experiment it appears that the matter of whether the chamber was light or dark did not afftect which chamber the pill bugs chose to go into. The data we collected does not show a clear pattern in the chambers that the pill bugs choose. We thought that the pill bugs would move to the darker chamber after 30 seconds, but the pill bugs more often were in the lighter of the two chambers. Our hypothesis stated that if a pill bug is given the choice between a light chamber and a dark chamber, then the pill bug would choose to move into the darker chamber. Over the course of conducting this experiment, we switched which chamber was covered to make sure that the pill bugs did not favor one over the other. This; however, did not seem to matter to the pill bugs because they seemed to be more preocupied with eachother rather then whether the chamber was dark or not. In order to improve this experiment, we would isolate the pill bugs to separate sets of chambers to prevent pill bugs from being influenced by surrounding ones. After researching, we found that pill bugs generally prefer a darker environment over a lighter one (McKenzie, Greg). This happens to support our hypothesis, however our data did not prove this statement.

Conclusion:
After observing, recording, and analyzing our data, our group concluded that the Pill bugs that were placed in the choice chambers preferred the lighter environment over the darker environment. The results that we displayed did not support our hypothesis; “If the environment is dark, then the majority of the Pill bugs will choose that environment, over the lighter area”. After our scheduled five minutes was concluded, three out of the five Pill bugs were located in the lighter chamber, compared to the darker chamber, which was covered by a block to induce darkness. We repeated our experiment a total of three times, and during the two other repetitions of our experiment, our numbers varied, but the overall results remained the same; the majority of Pill bugs were located in the lighter chamber. According to our experiment, it is clear that the Pill bugs prefer a lighter environment.
To improve our groups experiment, we would have added more Pill bugs, so they would not travel to one side just because they were forlorn. Also, we would have made the dark chamber darker, because it was white when we conducted our experiment, so light reflected inside of the chamber, and was not as dark as we preferred.

Conclusion: In completing this experiment, we discovered that if given a choice, the pill bug will choose to go to the wetter environment to live in, as opposed to the dry environment. As shown in our data table, after three minutes, all six of our pill bugs were in the wetter environment. This data proves that our original hypothesis was correct, for we said that if given a choice the pill bug would go to the damper environment. We believe that the pill bug prefers the wetter environment to live in because of the specialized gills that they have to breathe in a more humid climate. If given another chance to preform this experiement, we would use more pill bugs, we would test different variables such as: pill bug size, varying moisture levels, and soil and dirt from various locations, to see the effect that any of these things have on the pill bug's decision. The results that we have found are definitely conclusive, for we now know for a fact what type of environment that the pill bug likes to live in.
