Each partner picks a tree (deciduous) in their school yard. The main aim of the project is to familiarize children with the characteristic features of the four seasons through observations of a tree. Children will do searches about the tree, observe changes and explore nature in the course of direct observation. The partners will introduce their tree, take photos (collages), make videos, make drawings, posters (padlet) and upload all material on common Twinspace. The project will last throughout the school year from September to May.
