Justin B. believes that the temperature lowering 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 14 of the plants in the 60
degree temperature had been to change colors and only % of the plants in the 80 degree
temperature began to change colors.
