The overall objective of SESAM is to increase the understanding of researchers role in society with a particular emphasis on young people and their families any general tool increased understanding of how research contribute to societal benefits. It’s part of the European Researchers Night and we use the school as the main hub for our activities and to engage young people, their teachers, their peers, their families along with mentors from local community to contribute to that improved understanding. We use a thematic approach to science communication in the sense that food, nature, climate and the green economy form the foundation for all activities. Each year we work with a portfolio of schools over the spring to prepare different installations, prototypes, mock ups and learning stations that represent some kind of scientific challenge and some kind of insight into what good research can do to address that challenge. All installations, prototypes, mock ups and learning stations are prepared over the spring and summer at school and are put on exhibition at the final SESAM event right after the summerbreak. The final event takes place on the official European researchers night date end of September. In both the 22 and 23 rounds we used two locations: One in East of Denmark in cooperation with Swedish partners and one in the South West of Denmark in cooperation with German partners. As such SESAM includes three countries with DK as the main contributor and Germany and Sweden as co-contributors. In all case young people and the science teaching at school functions as the setting in which we practice science communication to a wider audience. We communicate science in a very popular way using tools such as demos, panel debates, posters, intermezzos, quizzes, foodscape walkabouts science slams and similar activities. We apply a cross disciplinary approach involved in both the natural sciences the humanities and the social sciences.
