"Water is one of the most essential elements of any kind of life on Earth and we are facing a difficult period in the upcoming decades. Clean water bases are diminishing while the demand for water is increasing. Water is a cross-cutting issue that affects all aspects of development, including health, food security, economic development, ecosystem services and biodiversity. The particular focus on water, climate and resilience aims at cooperation and initiatives in the area. The latest objective of the United Nations' Sustainable Development Goal 6 is about ""clean, accessible water for all"". The teaching and training activities in the project and their outcomes were to set a standard for this very important goal. We wished to show how educational institutions and the local communities behind them across Europe could promote Goal 6.As teachers we could not sit back and watch the future of water, we had to be proactive in its preservation for the upcoming generations. The educational methods and approaches we used in our project were varied and as modern as possible as we felt the traditional classroom methods may not be sufficient for such a wide topic. That is why we aimed at creation of a multidisciplinary and hands-on approach to teaching that could only be achieved when discovering the various spheres that our partners could offer based on their special skills/expertise.The basic priority behind the project was to lay the methodological foundation of ‘good practices’ together with the teachers involved in the project.We aimed to create a methodological model, which enabled us to make an interdisciplinary educational program for the ages of 13-17 at secondary level as this age group was the main focus range of our project activities. With the help of the programme students could understand the importance of water, and how much it intertwines all fields of life. It was also essential for students to comprehend the vulnerability of water bases and the diminishing quantity of resources as well as the need to find ways of sustainable water management. Furthermore, students also realized how important it is to work in a multinational project. They also learnt a lot about culture of other participating countries and found out that their peers from the other countries face the same challenges and problems as them. Great friendships were formed during the project not only among the students but also among the participating teachers. They had great possibility to talk to teachers from the other countries about their work and gain new experience in the field of methodology and teaching.The international work was called into life with a clear intention of seeing the participating teachers become better educators, as they shared the knowledge from their own expert area with others. The educational areas, subjects that we aimed to develop were language skills, language teaching, history, geography, biology, chemistry, economics, environmental studies, water management studies, and maths.Throughout the two years we have managed to create a set of MM teaching materials which were used in classrooms of participating schools. These materials are closely connected to water, water supplies in participating countries, water treatment and management. Students have learnt how similar and also different are approaches to water issues in participating countries. They have also learnt a lot about the ways we should treat water to ensure sustainable water management. That reflected in creating of the Water Charter that includes ideas from all participating countries. Apart MM teaching materials a set of playful materials was created. As all students enjoy games, it was the way how to motivate them to learn more about the project topics. They were able to enlarge their vocabulary connected to the project topics due to creating of the multi-language dictionary. The dictionary includes terminology we have learnt on international meetings. All the project results have been disseminated on e-twinning and school project website. In this way not only the schools but also the local community and local authorities have learnt about the project and its results."
