July 15, 1999

To begin class today, the students presented their results from the garbology lab they did in the evening session the day before. The students' assignment was to gather a hypothisis as to what kind of family their subject was based on garbage that the students were given.

Next, the students used STELLA®, the modeling software, to model how phospherous flows through lakes based on several variables. The students then chose a subject that they would work on making a project for presentation on Saturday. The students chose groups of two for their projects and worked in those for the afternoon.
