As the school semester winds down, lessons for the Aquatic Ecology class I've been teaching have been easier to prepare. For the past three weeks, we've been taking field trips! Field trips are so important to learning; while those experiences may not have included the most informational content, the knowledge gained was always so much more memorable. They also open opportunities for creativity and questioning that seem closed off in most students (and teachers) within the confines of a traditional classroom.
To start, we explored a park along the Meramec River in search of wetlands to delineate. This was part two for wetland ecology, as I had gone through a brief explanation of the concept of wetland delineation and how to identify soil type a few weeks ago. During the field trip, the challenge was actually more about finding areas in the park that were NOT wetlands. The river had just flooded the previous week.
Before the semester started, it hadn't crossed my mind to include a trip to a fish farm for an ecology class. Fortunately, I have Megan to toss ideas my way. She worked at the St. Louis Fish Farm while she was an undergraduate and, when I was trying to figure out what we might want to do during a lake/pond field trip, she mentioned that Mike, the owner of the fish farm, would probably be glad to host us. What a great idea!! Not only did we have a chance to explore a different ecosystem, but there were opportunities to consider the support systems are put in place at a fish farm, what ecological function these systems serve, and why the farm pond does not provide these services without human intervention.
During the visit, several students had an opportunity to try to catch a fish with the nets - each of them took several tries to catch a fish and some never did get one. I wanted to try, but made sure that all of the interested students had a shot first. I was a bit concerned that I would somehow embarrass myself - not only did I manage to catch a fish, but I got it on my first try! I was pleased to represent the Knouft Lab so successfully!
Initially, our field trip to the National Great Rivers Research and Education Center was scheduled for early April. Unfortunately, the flooding on the Mississippi River forced us to postpone the trip. On the other hand, this trip was completely worth the wait! The class split into two groups: one group toured the NGRREC research facility while the other group went out on the Mississippi in the research boat to explore monitoring methods for big rivers. It was very interesting to compare how methods change when you move from a wadeable stream to such a vast aquatic habitat.
