This Franco-Norwegian exchange is a cooperation between young people on a subject that is both artistic and environmental: discovering the issues and tools of each territory. To do this, they will develop their curiosity, their imagination, their ability to speak, their ideas for creating a show and short films. Their theme: Sun / Night, what adaptations for neighbouring countries? These weeks will be rich in exchanges, outings, workshops but will also be the result of a year of correspondence epistolary in English.
