DOING SCIENCE! Using the Scientific Method
LAB REPORT
Name ______
1. Background and purpose:
The purpose of this lab is to observe the pill bugs lifestyle/behavior. We have already determined that the pill bugs like moisture. Their kinesis stated that they would not move in a moist area. We think that the pill bugs will …………when exposed to…………
2. Isopod Observations (what did you see and Observe? Include the drawing)
a. How do the pill bugs seem to sense their environment?
b. Can you tell the difference in males and females?
c. How many eyes do they have?
d. How many legs
e. Do they exhibit dominance behaviors?
f. What are some stimuli they seem to respond to?
g. What was the environment like where you found them?
h. What do you think they were eating?

STUDENT EXPERIMENT
Problem:
We want to know if the we put in…………..then the pill bug will……..
Hypothesis
I believe that If we do this………………..THEN the pill bug will do………………
Experimental Design: We set up a petri dish and placed 5 pill bugs in it. Then, we divide our dish in half using a marker. We put ______on half of the dish and observed what happened.
Independent Variable The variable that changes on its own without help Ex: Time, Distance
Dependent Variable The variable that depends on the independent variable What is happening during time, or distance, etc.
Controlled Variables The variables that we don’t want to test wind, weather, temperature, light, plastic of petri dish, size of bugs
Description of the Design (so someone else could do it). This may include a sketch.

Conclusion (do your data support your hypothesis?)
Was your hypothesis correct? Why?
What could you do to make the experiment better?
Make any other predictions why data turned out the way it did.
