It is an environment project. Students will learn how to recycle, reduce and re-use the waste. The main idea is to create an "exchanging day challenge" in May : Exchanging instead of throwing !!! You could come with a thing that you don't use anymore at home (a clothe, a book, a toy...) and try to exchange it to something else. If many schools could organise this day, maybe the planet could go much better !! That's our idea !! Would you organise such a day in your country ? Hope so !!
