Procedure: We will observe the color pattern and physical differences of 3-5 separate species of trees every 3-4 days. We will make charts and graphs to display our data based on our observations and research.

Research: We will research the physical make-up of the leaves and root structure of each type of tree.

The article written by March Archetti, "The Origins of Autumn Colors by
Coevolution", is about the reasons as to why leaves change color. He
mentions three main reasons: the pigments in the leaves change their
structure, the synthesis of new pigments in autumn, and the soexistence of
insects. A large portion of his article is dicussing the strategies in
which trees will produce brighter, stronger leaves.
