The aim of the project is to exchange with several classes from european twinned cities (Gennevilliers, Imola and Ostrowiec) about the school garden. Different media will be considered: drawing, game, photography, poems, songs, … This exchange will be the opportunity to discover twinned cities of Gennevilliers and children by their work on the garden. The final goal is to make a final production as a digital herbarium (with all the herbs and plants of the project)
