This project is about working in a collaborative way with several colleagues and students in-school and out-of-school, with the aim of studying the different effects and evidence of climate change in the countries involved. It is also about celebrating two international events related to the protection of the environment and to some of the 2030 Agenda goals: the International Earth Day (April 22nd) and the International Day for Biodiversity (May 22nd). Before and after these events, our project aims at increasing students' awareness of the importance of studying Science in order to promote concrete actions to protect the environment and strategies for sustainable development. The idea is to set numerous activities where students will be protagonists and will work on a common ebook to highlight their discoveries. All the activities will be documented in our twinspace, day by day. The project will end with a dissemination of the celebrations and of the results of the students’ discoveries (interviews, researches, photos, videos) in and out of the schools involved (other students, parents, school websites).
