This partnership involves FIVE secondary schools and FIVE countries : Bulgaria, France, Germany, Italy and Sweden. The project will take place between September 2015 and June 2017. Its theme is in the sphere of the problems which the contemporary world is facing such as the lack of responsibility towards the future generations and the indifference towards the irrational use of water supplies in daily life. Water is a key issue for the survival of humankind on this planet. More and more regions lack water to grow the food they need and that’s why we need to take immediate action. Hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy, accounting for 16 percent of global electricity generation – 3,427 terawatt-hours of electricity production in 2010, and is expected to increase about 3.1% each year for the next 25 years. The project itself will focus on the understanding of water pollution and the preservation of water supplies. The project is relevant at a local, regional, national and European level. Through its activities, the partnership offers a solution to certain needs like lack of rational behavior towards the use of water on a daily basis and ignorance of ways of reducing the waste of fresh water. Our main target group is pupils aged between 15 and 18 years old. Through this project we want to contribute to the improvement of the water preservation problem, to the consolidation of the European dimension of education, to promote the values of European citizenship as well as the concern about the environment. The project will have an impact on students, teachers, local, regional and European community. The participants will improve their knowledge of the subjects involved in the project and spread our motto: “Water is life – Let's preserve it!”. They will develop their competencies and linguistic, civic, social and digital abilities; they will also assume the values of the European citizenship and the responsibilities for the environment. The students and staff have the possibility to communicate with other cultures and educational systems so they can understand and appreciate the multicultural European dimension. The project's activities will contribute to the education of the target public in the spirit of sustainable development by making some small changes in the behavior concerning the saving of water supplies in daily life and having eco-friendly habits. Some results of this partnership are: - a project logo; - a digital booklet with pictures, maps and graphs on water resources and pollution in each partner region; - "Save water at school" posters; - digital booklets on topics studied during learning mobilities; - a calendar with pictures of partner schools and towns; - water knowledge quizzes; - a video report on activities done during mobilities; - a basic conversation guide in English and the five national languages of the partnership. Some activities : - celebration of World Water Day in March and Europe Day in May; - "Save water at school" poster contests in local elementary schools; - research on microparticles in water, endangered species due to pollution of rivers; use of water in industries (dairy products, Champagne), hydrologic cycle; - field trips to sewage works, a dairy factory, a vineyard and Champagne making site, dams, a large aquarium, a modern water plant. The project thematic is linked to the curricula and the work on the project will respect the principle of interdisciplinary work. The activities will include : - library research activities; - linguistic preparation activities; - workshops; - discussion; - digital production of materials; - laboratory experiments.
