Using live organisms in class is part of the thrill of doing science. From bio-bottles to class “pets” to observing evidence of photosynthesis, live organisms add that WOW factor that can engage students in science. Some of these organisms may become ecological hazards if released into the wild. Practices of giving away organisms to families; dumping water outside or down sinks; planting school gardens with invasive plants; or releasing organisms into the wild can exacerbate the already formidable problem of invasive species in Great Lakes ecosystems. Participants gain understanding of the legal and environmental issues of aquatic invasive species in addition to resources for environmentally safe alternatives to current classroom practices.
