Photos from AP ENVIRONMENTAL SCIENCE  … teacher Andrew Milbauer explains what was happening:

We were capturing and marking crickets in the school prairie.  This technique is used as part of a method of population estimation called mark/recapture.  You capture a certain number of crickets, mark them with environmentally friendly paint, and release them back into the prairie.  A few days later you return to the area and capture more crickets.  You can then estimate the total population of crickets based on the number of crickets that carry marks showing that they were part of the population caught the first time around.

and in ENVIRONMENTAL MONITORING …
In the canoes we were learning to create lake profiles.  We collected water with sampling tubes at various depths.  Each sample was then measured for temperature and dissolved oxygen.  I learned this method while at UW Madison studying limnology.  We will enter this information into a database to create a long term study of the lakes on campus.
