This project is focused on how excessive energy consumption affects our ecosystem, and in possible solutions to be implemented in the larger scale, like resorting to renewable energy, and in everyday life. In particular the pupils will learn how to save energy at school and at their homes. In doing so they will therefore learn concepts and skills that integrate with several subjects (science, technology, citizenship, art, English, mother tongue, etc.). The project is linked to Goal 15 Life on land (Agenda 2030), "Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss"). The partnered schools will agree on a calendar of activities that will guide the participants throughout the project. Students and teachers will develop the activities together, and share the results using a range of tools, including webinars. The students will work within national and international teams, collaborating and providing feedback (comments to posts, forums….). They will be also involved sharing surveys, interviews and challenges.
