The paper informs on the characteristics of a Comenius Network of seven organizations, who are collaborating in exchanging best practice on science camps. This exchange includes evaluation results on more science camps of European organizations, which will deliver information on organization, collaboration with companies, pedagogical aspects, as well as sustainability on career decisions. The results will be distributed online, and in a series of workshops. First results of a pan-European survey on Science Camps and on participants of a German science camp are reported.
