Sometimes one could believe the general public limits its environmental consciousness to problems of emissions and waste disposal. Environmental educator Sebastian Hemmann tries to raise awareness to another, often overlooked issue: virtual water - the enormous quantities of water embedded into everything we produce. How is this topic addressed in schools? The German Water Protection Association (Vereinigung Deutscher Gewässerschutz) has published a workbook for school classes. “Virtuelles Wasser – Versteckt im Einkaufskorb” (Virtual Water – Hidden in the Shopping Basket) is used among many schools in Germany by teachers and their pupils. Sebastian conducts a comprehensive survey about its success. His findings reveal interesting insights into the teaching of a topic as interdisciplinary and relevant as virtual water. His conclusions about didactic methods and successful pedagogy can help in any school class or environmental education program.
