Abstract

Tiny pieces of plastic, including microfibers, can impair the behavior of marine organisms in a variety of ways.  Microplastics have been detected in the Great Lakes environment but little is known about their impact on the biota.  Given the potential for widespread effects across multiple species, a first step in this kind of research is to narrow the focus to specific vulnerable taxa and key behaviors.  We leveraged the creative enthusiasm of eighth graders from Willowcreek Middle School (Portage, IN) to explore how the behavior of common freshwater macroinvertebrates that have been exposed to polyester microfibers may differ from organisms that haven’t been deliberately exposed to microfibers. Data from the students’ short behavioral assays then informed the university scientists about taxa to target for further experimentation. Through this project, students learned skills in scientific inquiry while scientists gleaned valuable information about which organisms may be impacted and in what ways.  This laboratory project tied into a larger education initiative on watershed health where poor water quality can impact public health. Monitoring has focused in the Salt Creek watershed where streams are popular for fishing and empty into Lake Michigan at busy public beaches.
