1. Our Experiment of Pill Bugs By The Mad Scientists Eric Kaufman Malia Norton Kris Norton Brandon Nase Armadillium Vulgare

2. Our Observations The colors of our pill bugs were gray with a white underside. All of our pill bugs had an anterior and posterior end. Each pill bug had 14 legs and two antennae. We observed that the legs move sequentially, but not all at the same time. Because they were in containers, their movements were mainly in circles. All of our pill bugs appeared to congregate in groups. The pill bugs also seemed to prefer darkness over light.

3. Questions We first thought that we could measure the effects of the pill bug’s movements by removing its antennae. But, there was no solid movements we could measure. We then derived another question, asking if elements, such as rocks, leaves and bark, were added to the environment which one would the pill bugs prefer.

4. Hypothesis We were able to come up with a hypothesis from our second question: When given a choice, the pill bug prefers to hide underneath bark, instead of hiding underneath rocks and leaves or staying out in the open.

5. Prediction If we provide the pill bugs with multiple hiding places, then most of them will choose to hide. If we give the pill bugs a choice to hide underneath rocks, leaves or bark, then more will choose to hide underneath the bark.

6. Testing Our Hypothesis To test our hypothesis, we took a large rectangular container and placed our objects in the container. Our objects included a piece of bark, two leaves and two rocks. After placing the container and objects in a dimly lit area, we placed ten pill bugs in the container. We waited for 20 minutes and checked to see which hiding spot they preferred.

7. Results of our Test Here were the results of our test: LeavesBarkRocksOut in Open Number of Pill Bugs 1081

8. Our Conclusion Although we thought the pill bugs would prefer the bark, at least they preferred another hiding place other than out in the open. Number of Pill Bugs per Shelter Type of Shelters Number of Pill Bugs
