The GSCN and the Schering Stiftung developed new material about stem cells for high schools in German. The four units á 90 minutes cover the topics "Basics, Ethics, Therapies, Genetics" and offer an insight into the wide area of stem cells and related fields. Teachers find a didactic concept based on elements of a scientific conference - students slip into the role of scientists and give key lectures, present posters and discuss on panels about all kind of aspects about stem cells.
