We started our study at the beginning of September. We watched one maple tree each week. We took the temperature of the ground and air. We took a picture each week in front of the maple tree. We looked for Robins each time we went out. On September 17 we noticed that our tree leaves were changing yellow. We also saw pink and red trees on the hills around us. The robins were gone by September 17 and by October the air temp had dropped 30 degrees
