This Erasmus/eTwinning project involves five schools from Italy, France, Spain, Germany, Greece and stems from the idea that Service Learning is a methodology that can revolutionise our teaching practice, the way our students learn, while providing benefits to local communities. We believe Climate Service Learning is a powerful tool to fight climate change from schools, to build responsibility and awareness, to create links with local communities, to enhance opportunities for learning and developing personal and social skills, as well as to strengthen the social and responsible dimension of scientific subjects like natural sciences, chemistry, biology, physics, economics and many others.
