Motto: "When the mind experiences peace, the body will flourish with good health” Karishma Ahuja. This project pretends to foster the knowledge of students and teachers about these three Sustainable Development Goals: SDG 16 ( peace and justice), SDG 6 ( clear water and sanitation) and SDG 3 ( Good health ). Our common challenge is to involve the whole school community to collaborate in the project as it will become an interdisciplinary eTwinning school project. the Catalan school, col·legi Sant Josep is an eTwinning school and monitoring school, so that will help the French school to start with this new experience which will be fruitful for all teachers, students and other staff.
