In Uppsala the Museum Gustavianum occupies a unique position as an interface between the academic world and the general public. Situated in the medieval heart of the city, the Gustavianum is the former main building of Uppsala University. The Anatomical Theatre erected on the roof of the Gustavianum gives the building its characteristic appearance. The Museum Gustavianum was inaugurated in 1997. The main exhibition describes the history of Uppsala University through a collection of objects from a wide range of disciplines dating from 1477, when the university was founded, to the present. The museum has become a popular attraction to the public, with around 50 000 visitors every year. Ever since the museum was founded student participation has played an important role in the ongoing project with respect to documentation, exhibitions and education. In our public work we start with preschool children. Twice a year since 2004 the Museum Gustavianum has collaborated with the Department of Education at the faculty of Education at Uppsala University. Each term around fifty students from the preschool teacher section plan and implement a number of museum lessons for specially invited kindergartens. The collaboration begins with a lecture in the Gustavianum how to use a museum as a learning environment. Each museum lesson, which is prepared by the students, is based on inspiration gathered from the museum´s collections. In the project the Museum Gustavianum can support both students in their education to preschool teachers and the children´s joy in finding out how exciting experiments can be. At the museum we have found the student participation to be a win-win concept. Museums have unique collections and a great many stories that need to be told. If the museums dare to let in other explainers as teachers, students and researchers, then together we can connect the past with the present and the future. Then our museums can become laboratories for new ideas and our collections can find a new meaning.
