Answer:
Read the description of the experiment, then answer the questions that follow.
a) Is the microbiologist’s hypothesis testable? Why or why not?
A microbiologist studying bacteria hypothesizes that a colony will double
in size overnight if she increases the temperature of their surroundings
by 10 C from 25 C to 35 C.
She increases the temperature before leaving for the day and checks the
colony the next morning. She observes that the size of the colony is the
same size as it was the day before, despite the change in temperature.

b) Which variable is being tested (independent variable) in this experiment?
c) Which variable is being measured (dependent variable) in this experiment?
d) Is this a controlled experiment? If it is, explain how. If not, describe how to modify the
experiment so that it is a controlled experiment.
e) Identify three variables that must remain constant throughout the experiment.
f) Suggest another improvement that this researcher should implement to improve the
experiment.
g) Suppose that this researcher made the necessary improvements to her experiment, yet
the bacterial colony remained its original size. Does this mean that her experiment is a
failure? Explain your answer.
