The premise behind the forest school philosophy was simple: Stimulate children’s physical, cognitive, and social development by spending as much time as possible in nature, every day, all year-round. At forest school, nature becomes a classroom with no walls, where children learn through self-directed play by using their whole bodies and all of their senses, in an environment that nurtures their curiosity and strengthens their self-esteem. In the process, the thinking goes, they will become responsible stewards of the land.
