Class discussion
Share your conclusions with the class.
83 A Suitable Habitat
What effect do you think changes in the
habitat might have on the size of a population
of blackworms?
For example, would the blackworm population
grow larger when gravel is available compared
to sand?
Share your thoughts with the class.
83 A Suitable Habitat
While both the leaf litter and gravel provided
good habitats as tested in this activity, which
of these two materials might better provide
other essential needs, like food?
Share your thoughts with the class.
83 A Suitable Habitat
How important do you think non-living factors,
such as substratum, are in affecting the size
of a population?
For example, how might an increase in rainfall
affect a population of earthworms?
Share your thoughts with the class.
83 A Suitable Habitat
Imagine
Imagine that heavy floods resulted in the deposit
of sand into the blackworm habitat.
What do you think would happen to the size of
the blackworm population?
Share your thoughts with the class.

Analysis question 1
Based on your experiment, which type(s) of
material provides a good habitat for
blackworms? Explain how your experimental
results support your conclusions.
83 A Suitable Habitat
Analysis question 2
Describe the non-living characteristics of a
habitat. Hint: What non-living factors could affect
whether organisms will survive and reproduce?
83 A Suitable Habitat
Analysis question 3
What could you do with your blackworms to
investigate if a warm or cold habitat is better for
them? Write a procedure that anyone in your
class could follow to investigate this question.
