Four different approaches will be presented where science centres promote innovative training courses for school teachers, offer workshops and outreach in schools as well as at the science centres. Questions will be addressed, such as how relationships between pupils, teachers, scientists and science centres have been built up, how enquiry-based learning can be offered in elementary schools, and how informal education might be useful for a formal education agency like a school. What impact can a young scientist’s appearance together with a science centre educator have on schoolchildren?
