Rolly Polly Lab

By: Mikaela Stokes & McKenzie Ivins

Problem:

I wonder what would happen to pill bugs if we separated them and gave them the choice of dry or damp and covered or exposed environments, checking every 30 seconds for 5 minutes.

Hypothesis:

If the pill bugs were given the choice to be in covered or non covered and damp or wet place, then they would be in a dark damp place due to them normally being found under moist rocks.

The manipulated variable in this lab is...

Moisture or not

&

Covered or not.

Procedure for Manipulated Variable:

1. Set up 5 petri dishes with one in the middle of all 4.

2. Cover 2 of the outside petri dishes and places a wet paper towel in one covered petri dish and one non covered.

3. Place bugs inside the middle petri dish.

4. Record location of pill bugs every 30 seconds for 5 minutes.

5. Analyze data and come to a conclusion.

Procedure for Control:

1. Set up 5 petri dishes with one in the middle of all 4.

2. Place bugs inside the middle petri dish.

3. Record location of pill bugs every 30 seconds for 5 minutes.

4. Analyze data and come to a conclusion.

Control:

Experiment Observation:

Analysis:

5.94 < 9.488

Due to the chi test, we have failed to reject the nulls hypothesis.

Conclusion:

According to our observations, the data does support our hypothesis because the bugs favored the wet and covered petri dish over everything else.
