‘Water Out Precious Treasure” is a title of the project which was carried out in five partner countries: Poland, Germany, France, Bulgaria and Romania. The partnership was a continuation of the previous projects or meeting new partners at an international course. The main objective of the project was connection with scientific and natural science subjects, which had an influence on an attractive profile of a school – leaver in the future labour market, cooperation on regional and international level in pursuing questions connected with environmental protection and water management, improving or obtaining new language competences especially practical ones such as speaking, using modern technology, coming up with innovative solutions and creating resourceful model of a young European open to the problems of modern Europe and the world, taking innovative and venturesome actions in order to achieve the goals. The results of project work were numerous presentations, albums, films, posters, photos, recordings, exhibitions, scripts, descriptions, interviews, articles and comparative statistics.In the project lasting for two years, there were about 200 students and 33 teachers involved directly and about 2000 students and 150 teachers involved indirectly. The participants came from different schools- general secondary, vocational, vocational – technical ones, the students were from 16 to 19 years old and they represented distinct social spheres and various ethnic nationalities. Project activities were connected with innovative methods of teaching so integrated a lot of cooperating institutions, which enabled us to get a direct contact with education.Each partner school prepared a work schedule in a way to present the most interesting information and unique methods of water management in the region. We learned innovative methods of water testing, influence of rainfall on the quality of the soil and connected with it agriculture. We participated in numerous laboratory classes, experienced direct contact with education by visiting different institutions: water treatment plants, water bottling plants, organic and traditional plantations. We learned innovative methods of testing water quality or purification without using chemicals. We also acquired a new skill of making a business plan and managing our own company. Moreover, in order to get to know each other we exchanged experiences and ideas during intercultural and artistic workshops. The abundant plan of activities during the international exchange visits provided students with substantial number of contacts and thanks to the applied communication means students used English in oral and written forms while working on interesting assignments connected with environmental and water management issues.Project activities enabled students from five European towns to open to other cultures, to learn environmental problems of partner schools’ regions. Project activities also made students aware of the fact that only by collaborative effort on international level we are able to make a big step towards environmental issues, which in consequence means improving quality of our life.Interesting and varied project activities using modern technology made students interested in scientific and natural science subjects, students promoted learning these subjects and as a result we hope they encouraged peers to improve their knowledge in this scope. By many dissemination activities students and teachers from other schools in the region learned about the project and its results, in consequence we hope they will take action in order to plan similar projects in their schools. The status of the school in the local environment was improved and therefore more stakeholders were obtained for school.To make project activities interesting, different methods of work were used: direct contact with education, workshops and laboratory classes, panel discussions and at the Forum, work in international groups, project work, preparing presentations. The quality of our work was checked by means of systematic evaluation: surveys, questionnaires, interviews, SWOT analysis.Teachers participating in the project improved their competence in the field of methodology and didactics, their workroom was enriched by using interesting project results. Mutual work shared with partners from five partner countries enabled us to reassert already existing bond or establish a new lasting partnership when it comes to new partners. The desired effect of teachers corporation will be steps taken in order to form a new partnership in the future and exchange of practises in action ‘job shadowing’.
