Local governments (municipalities, regional governments, etc.) and science centres or museums could collaborate to set up networks in order to develop complex projects aimed at an extensive public. For instance, they could promote educational or communicational programmes aimed at the school system of a whole region and concerning a problem of public interest like an environmental risk. In this framework, how could science centres and the like play a role in such a complex initiative not only providing educational contents but also acting as promoters of public debate?
