the Regional Association for the Introduction to Nature and the Environment in Alsace (Ariena) proposes the establishment of new educational experiments allowing children to regularly experience experiences in contact with nature, discover their environment and learn from them various individual learnings (scientific, creative, motors, etc.) and collective (cooperation, etc.). The main objective here is to recreate direct links between children and nature, to allow them to be interested in living, to give them taste for science, by taking them out on a weekly basis throughout the year, regardless of weather conditions. To this end, Ariena will accompany nature and environmental education associations, teachers and educators, and will coordinate the project as a whole. This collective and participatory project will also lead to the realisation of a pedagogical guide based on the realisation and evaluation of the various experiments. It will be intended to be disseminated to educational and scientific bodies with a view to promoting the dissemination of external pedagogical practices.
