The RiverWeb Water Quality Simulator (WQS) is part of an ongoing, collaborative design experiment to refine tools and strategies supporting inquiry into watershed dynamics, particularly physical, chemical, and biological processes determining water quality. The Web simulator enables high school science learners to investigate how land use and precipitation affect water quality within an archetypal watershed. A digital notebook allows students to record observations and articulate hypotheses and explanations, and teachers to structure, scaffold, and assess student activities. The WQS builds on and extends the Maryland Virtual High School (MVHS) Core Models Project in which teachers collaborate to develop and implement computer modeling activities designed to promote core science concepts such as the interdependence of ecological systems.
