The book explains the development history of experimenta in the context of the educational institutions Science Center, Planetarium and Schülerlabore (Educational Laboratories). In addition, the contentual and methodological-didactic concept is conveyed clearly. The volume is rounded off with further information about the architectural design concepts of the two experimenta buildings: the repurposed historical Hagenbucher warehouse and the spectacular glass and steel new building by Sauerbruch Hutton.
