Background Information:

In our lab we were working with isopods, also known as pill bugs or rollie pollies. The isopods that we worked with were land isopods. They like to live in moist places under untouched objects such as boards, bricks, rotting logs and or rocks. Basically, they will live anywhere! If you are lucky enough, you can even find them next to buildings where it is moist and if there is food.

While the same animal my not wanting to eat something that is not sugary or sweet like peas.

At the beginning of our lab we had placed the pill bugs in the petri dish with dry filter paper and we observed their behavior. The pill bugs were going around the inside rim of petri in circles following each other, almost as if it were a game of tag. The pill bugs never seemed to stop moving, flipping over and were constantly climbing. Some of the pill bugs even tried to escape from the petri dish, but our group was quick to make that didn't happen. As our lab went on, we placed the 4 different pieces of filter paper with solutions on them and then added 4 pill bugs to it. We collected lots of information during this procedure.

This table represents how many pill bugs were on each slice of filter paper, that had a different solution on each of them, over 30 second intervals lasting 5 minutes. This is what were recorded our data on for this part of the lab.


The purpose of our experiment was to observe the behavior of the pill bugs. We were trying to find exactly whether the pill bugs would be attracted or repelled by the chemicals. The chemicals used were vinegar, water, salt solution and a sugar
