Our project Erasmus CSI (“Climate Scenes Investigation” deliberately related to “Crime Scene Investigation”) deals with the issue of climate change and wants to promote a better understanding of the human footprint. Climate change is our main global problem and deeply concerns all generations - especially our students' generation as shown by the environmental movement “Fridays for Future”As schools from our four partner countries we want to analyse current and future scenarios of climate change whereby we will not only look at global developments but also observe how this issue already affects our local surroundings. CSI will motivate students to work together to uncover challenges as well as discover solutions –both politically but also on a personal level (eco-friendly behaviour).Erasmus CSI is scheduled to last for three years. In the first year we will only have short term meetings while in the second and third year some of our students will also participate in long term mobilities of up to three months. Prepared for this by online language courses, they will fully integrate in their partner school's everyday life and make valuable cultural experiences that only a longer stay in another country can provideAround 12 teachers and 90 students aged 13 to 18 will participate in CSI on a regular basis. The project will help inclusion by integrating students in a cooperative project and giving students from low income families the opportunity to travel abroadStudents will be asked to present their findings to their peers and to the public. Hereby, they will produce many different kinds of works:-written: articles, questionnaires, presentations-creative: logos, leaflets, posters-audio or video: documentaries, podcastsErasmus CSI will apply the same methodology to each meeting and include:1-Introductory plenary session2-Workshops3-Excursions4-Closing plenary session (presenting the week's results)5-“Homework” (mainly, to prepare for the following meeting)Due to its demanding subject matter, CSI will greatly improve our students' oral and written expertise in English. On top of that, the ones involved in long term mobilities will also improve their language skills in German, Italian, Portuguese and Spanish. All this progress will be registered in their Passport of Languages for Europass.Our students' IT skills will improve through the application of various software tools (blogs, presentations, survey analyses, video- and audio editing, photos, layout software)The project will have both intangible results (knowledge and skills acquisition by the participants) and tangible results (material products). Reports, podcasts, videos, presentations will be shared on Twinspace and also at a final public exhibition in Rho, Italy. We will use these outcomes to measure the success of our project – especially in relation to the three priorities we selected for this project:-Environmental and climate change-Civic engagement / responsible citizenship-Teaching and learning foreign languagesThe project will have a significant long-term impact on its participants whereby the impact on students is expected to be the most significant. The first-hand experience of partners, and activities based on critical thinking and innovative methods will highly influence our students. By working in groups and collaborating with each other, they will gain competence in various areas and improve many social skills (negotiating, problem-solving, decision-making). The perception of our environment will also be changed since participants will gain a greater understanding of climate change based on analysis at the levels of biology, chemistry, demographics, philosophy, politics, economics, and social scienceThe teachers will also improve their knowledge on CSI-related aspects. The knowledge and experience of cross-curricular teaching, acquiring new methods and materials, and social skills and cooperation techniques will be improved. The ability to communicate better in English and competence in using ICT will be improved for all participants by the end of the project as wellThe partnership will have a positive impact on the participating institutions by building a community of teachers and students who have a strong commitment to and sense of ownership in the project, and by creating and carrying out several creative dissemination techniques and activities. It will also enable a broader community (parents, school authorities, local authorities, associations) to benefit from our partnership in the long term.The best practices of the project will be disseminated by sharing our experiences and products not only in our schools and local communities but also at conferences and workshops organized for schools interested in Erasmus+ projects by our national agencies. As a result, a wider audience will be reached and benefit in the long-term.We hope that our project will be an example of good practice in the lifelong learning community
