Pill Bug Lab:

Title:

Problem:

Hypothesis:

Procedure:

1. In your chambers and place a dry filter paper on one side, and a wet filter paper (NOT too wet, the petri dish shouldn’t be flooded. Pill bugs can’t swim. So please. Don’t drown my pill bugs. I will be sad.)

2. CAREFULLY Place half the pill bugs in the wet petri dish and half of them in the dry petri dish.

3. cover the chamber.

4. Observe their motion for 10 minutes, and record the number of pill bugs in each petri dish every 30 seconds.

5. Record results/observations.

Part 2

Now, Design you own experiment, in your experiment test something other than wet vs. Dry. Such as light vs dark, warm vs cold, etc. Write your title, problem, hypothesis, procedure, results, and graph in your lab book.

Variables:

Data: Record data in this chart (copy it into your lab book):

Time (min) / Number in Wet chamber / Number in dry Chamber / Other notes (observations)
0
.5
etc

Graph: graph your data on an x-y axis. Wet vs Dry for part 1 and your conditions for part 2

Analysis:

1. What conclusions do you draw from your data? Explain physiological reasons for the behavior observed in this activity.

2. Compare data with other groups. With respect to humidity, light, temp, and other environmental conditions, which type of environment do isopods prefer? How does the data support these conclusions? Give specific examples.

3. How do isopods locate appropriate environments.

4. If you suddenly turned a rock over and found isopods under it, what would you expect them to be doing? If you watched the isopods for a few minutes, how would you expect to see their behavior change?

Conclusion:

Now, Design you own experiment, in your experiment test something other than wet vs. Dry. Such as light vs dark, warm vs cold, etc. Write your title, problem, hypothesis, procedure and results in your lab book.
