Sample modified photos using
ImageJ:
In both photos the kudzu
appears as a yellow/orange color while the trees are purple/black.

The method of presentation
is up to the teachers. You may wish to have the students create posters,
web sites, digital presentations such as PowerPoint or simply speak
before the class. Be sure the students consider both the environmental
impacts and the number of years a method needs to be in place to remove
the kudzu.
For assistance on using Excel
to create graphs visit LabWrite (http://labwrite.ncsu.edu/www/res/res-homepage.htm).
