From some observations, a student noticed there are fruit flies flying around and
landing on a banana in the kitchen. The student wondered if a certain type of fruit
will attract more fruit flies than another. The student set up four jars of the exact
same size on the countertop in an area where the light remains the same. They
weighed the following fruits and placed 110 grams of each fruit into the jars:
banana, strawberry, peach, watermelon. The student had 4 vials of fruit flies (all
female, same species, same number) and placed each vial directly in front of jar. The
student asked a friend to take the cover off of two of the vials while they removed
the other covers simultaneously. An hour later the student recorded the number of
fruit flies in each jar and continued to record data every twelve hours for 5 days in a
row. In this experiment, what is the independent variable?
of fline in and what is the dependent variable and what is the controlled variable?
