A community project with the intention of developing specific communication on environmental issues for children age 3-7 allies with a theatre artist and storyteller. The result is a meeting between science and theatre. Theatre, with its borderline praxis between entertainment and reflection offered a precious opportunity to deliver difficult scientific or social issues within the environmental mindset to such youngsters, an opportunity well exploited and well received. But what makes Science Theatre an obvious choice in order to communicate natural sciences or environmental issues? What hides behind this label? Is this concept at all new? The purpose of this article is threefold: 1) to describe Science Theatre in terms of typology with specific focus on environmental subjects, 2) to address Science Theatre as a borderline meeting place (agora or arena) between science and theatre 3) to discuss its clear learning potentials in light of Science Theatre’s specific dramaturgical tools and historical tradition. We maintain that, by means of aesthetic appeal, theatre might be again one of the survival tools human beings need to bridge their lives into the centuries to come.
