Sow Bug Habitats
Answer Sheet
Part A
- Using complete sentences, predict what you think the sow bugs
will do, if they are released into a habitat with different
areas of moisture and light.
- Using complete sentences, explain why you think the sow bugs
will be arranged in the way you predicted?
Part B
- Did the animals prefer one environment to another? State evidence
for your answer in complete sentences.
- For this question, answer either (a) or (b)
- If most of the animals were found in the dark, moist side
of the container, would this be proof that sow bugs prefer
a moist environment to a dry one? Explain your answer in
complete sentences.
- If most of the animals were found on the illuminated,
dry side of the container, would this be proof that sow
bugs prefer light to darkness? Explain your answer in complete
sentences.
- Based on the way this experiment was run can you say the sow
bugs behavior was due to differences in light conditions alone?
Yes or No.
- Using complete sentences, explain your reasoning to question
#5.
- How could the variables in this experimental set up be changed
to allow for better conclusions to be drawn? Answer in complete
sentences.
- For this question, answer either (a) or (b) depending
on your results.
- If there is a preference, how does it relate to
their survival? In other words, how do the environmental
factors of light/dry or dark/moist make it possible for
them to be better able to survive?
- If there is no preference, explain why this
is the case in terms of sow bug survival and life processes.
