Expo-Sciences are non competitive multicultural exhibitions that showcase STEAM (Science, Technology, Engineering, Arts and Mathematics) projects developed by children and youth from around the world, as well as interactive exhibits by STEAM-related institutions.

The Expo-Sciences programme also includes cultural and scientific visits, leisure activities, and workshops, and conferences. National youth STEAM programme leaders meet to share and discuss best practice in STEAM promotion and education.

Participating in an Expo-Sciences is an opportunity to

  • Install and animate a space to highlight youngsters’, teachers’ and leaders’ efforts and interest in research, science and technology innovation, enhancing their motivation while contributing to their personal development.
  • Establish relationships with other institutions with similar goals through the development of scientific, technical and social projects in order to exchange ideas and create actions according to the needs of today’s world, for the benefit of industry, the educational sector and society at large.
  • Be represented at an international level through the young peoples’ projects, allowing for the spreading of knowledge amongst the main target audience (i.e. young people).    
  • Promote Scientific Culture in a multi-cultural environment, allowing the sharing of experience and good practice so as to achieve higher-standard scientific activities.
