Lately collecting papers, cans and pet bottles all that from home, as a one of learning for recycle in enviromental education, is found at many primary schools. But some pupils are not positive to these activities. Because they are busy at homeworks, private lessons and playing games. We must teach the concept of circulation in a nature to them who want to know a real object of activity for recycle. And we studied a upbringing of perception about recycle through the piling up protoexperiences at some lessons by biotope in a primary school. So they started to be interested in a learning for recycle and to find a importance of it for a nature.
