The final project for module 3 in a university course, where students are required to read a research paper on prescribed fire and grazing effects on carbon dynamics in a northern mixed-grass prairie, and use the techniques learned in lectures to find three models for the given data. The students must then decide which model is the most appropriate for the data and present their findings to the class.

Your group has been given the reference for a research paper, and a set of data taken from the paper. Read the paper with sufficient depth to know what the data is measuring. Use the techniques that you have seen in the lectures to find three models for the given data of form given to you. Decide which model is the most appropriate for the data
Your group will be given 10 minutes to present its work to the class during either November 3’s lecture or Novemeber 5’s lecture. The group will then have to answer at least two questions from the audience. The presentation should cover the following (not necessarily in order):
At the end of the presentation, the group will save the Mathematica workbook they used plus any other files they presented, and submit it in Moodle. Each student will give a grade to each presentation not given by their group. On Monday, November 3, three groups will be selected, at random, to present their work. It will be an Honor Code violation for the two remaining groups to do any further work on their projects.
