Last summer our
wonderful science department went on a department trip to D.C. for a Jason
Learning conference. While we were
there, we were given a field experience in the Great Falls National Park. Using
a netting, a pop-up table, rain boots and various hand tools, we looked for macro-invertebrates
along a stream. Using a dichotomous key and pamphlet guides given to us by the
program, we were able to determine the species present and determine if the
stream was a healthy stream or not.
We had a blast! Here
we were, grown adults, and we didn’t want to get out of the stream for lunch. I
can only imagine how excited our students would be if they were given the opportunity
to do this. This activity covered multiple TEKS including abiotic/biotic
factors, biodiversity, and dichotomous keys. As you can imagine, the teachers in
us were completely geeking out.




My goal this semester to simulate this same activity on our
campus. I’m meeting with our department chair to get the required materials to pull
this off! I also want to leverage it further by including a pre-lab study and
report at the end of the activity. Students would chart their data and type up
a report in the library, and if time allows, present their findings in class.
