Justin believes that the temperature decrease during the fall months is what causes the color of the
leaves to change. He set up an experiment wherein he placed some plants in 80 degrees rooms and
some in 60 degree rooms. He then observed the color of the leaves for a total of 1 month. At the end
of the month Justin observed that % of the plants in the 60 degree temperature had changed colors
while only of the plants in the 80 degree temperature began to change colors.
