Abstract
In this open-ended investigation spanning four lab periods, students explore the ecological consequences of the introduction of two invasive plant species, Autumn Olive (Elaeagnus umbellata) and myrtle (Vinca minor) at nearby field sites, each lab section focusing on one of the two species. In a modified jigsaw framework, six teams from each lab section design, implement, analyze and present experiments to answer six different, but integrated, subquestions, each deriving from a single “big picture” question: What are the consequences of an invasive species to the ecological integrity of the biological community?”
