Nearing the end of the school year students have a lesson on macroinvertebrate identification. They learn to use a simple dichotomous key to correctly identify the different species of insect larva, crustaceans, arthropods, or other invertebrates found in Fish Creek. They use their skills from this lesson and apply them to the organisms that they collect in lab station number three on release day. This information will help us build a population graph of the species present in the tributary.
Below is a video of our macroinvertebrate lesson.
