| Description | Students investigate the migration of small particles of plastic pollution by exposing invertebrates to fluorescent bead fragments in a controlled environment composed of lake or stream water. They set up microcosm models, introduce microbeads, and collect data using microscopes and blacklights. They document the ingestion of the plastic beads by the tiny organisms by diagramming the impact of microplastic pollution in the food chains and food webs they investigated. Student teams investigate the migration of small-particle plastic pollution by exposing invertebrates found in water samples from a local lake or river to fluorescent bead fragments in a controlled environment of their own designs. Students begin by reviewing the composition of food webs and considering the ethics of studies on live organisms. In their model microcosms, they set up a food web so as to trace the microbead migration from one invertebrate species to another. Students use blacklights and microscopes to observe and quantify their experimental results. They develop diagrams that explain their investigations—modeling the ecological impacts of microplastics. |
