T he weather made some days quite interesting. In the winter of 1996, we had to break through ice, we got stuck trying to go from place to place, and we had some close calls--nearly fell into the water.

Research Question: How are the pollution levels at the sites different and how are they the same? We thought the levels of pollution at the sites would dramatically change with the season.

Robyn: In the beginning we would go get water samples during class and it was fun because it was warm weather. Then winter came and there was a lot of snow and it was very cold and it became a chore. Sometimes we didn't really want to go do it.

Courtney: We would test the samples with a testing kit. Some sites were difficult to get to in the winter time. At one site, we had to break through the ice and put ice chips in the jar and let them melt.
