• Maroinvertebrates

    Macroinvertebrates are organisms that lack a spine and are large enough to be seen with the unaided eye. That also spend at least a portion of their life cycle in the water. In a stream or lake, they are indicators of overall water quality as various species can only survive is specific water conditions. Examples of macroinvertebrates include flatworms, crayfish, snails, clams and various insects, such as dragonflies and mayflies. As part of our "Salmon in the Classroom" project, you will be identifying and classifying various macroinvertebrates. This will help students identify the overall health of the water system we will be releasing our salmon into. Prior to releasing the salmon students will become "experts" on one particular macroinvertebrate.  Students will use their creative ingenuity to hand tie a custom fly mimicking the macroinvertebrate that they are assigned.  The poster for this project can be found below along with other lessons associated with our macroinvertebrate study.


    Below is our classroom lesson on macroinvertebrate identification.  Students 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.  The information gained will help us build a population graph of the species present in the tributary.
