The Department of Biological Sciences at Idaho State University offers this website as part of a project "to enhance teacher preparation in the sciences by emphasizing inquiry and experimental approaches to science teaching." The site offers one or two lesson plans (mostly at the high school level) for the following subjects: the cell; molecular basis of heredity; biological evolution; interdependence of organisms; matter, energy, and organization of living systems; and behavior of organisms. Most of these lessons appear to have been created for the website, a few come from external sources.
