"-Together with our pupils (15 - 20 years) from four European countries (Czech Republic, Netherlands, Slovenia and Germany) we concentrated on the des different aspects of water in our life. An integral way of viewing the topic was planned so that ther is not a merely natural-scientific perspective. We did not only carry out scientific experiments (meassuring the quality of water) but also had a look at water as an important resource für agriculture or industry. What kind of quality has water in our region? How is our daily life or local industry influenced by nature and water resources? Transnational perspectives were really important at this project. The schools are in rather different natural and social conditions. Water can be seen as chance (hydroelectric power station) or as danger (flood). We dealt with specific local political and social problems linked with water. Environment protection was be an important issue. Pupils paid attention to civil commitment and moral questions. They also worked in creative and artistic ways. We organized four international meetings for 140 puils from four countries. There was a cross-border experiement concerning water quality, photo-collections, videos about the meetings. Of course, there is also a website about the project. Each school organized a creative event dealing with the topic ""water"". (The results will be published in near future.) Almost all of the parterns had made positive experience at the erasmu+-project ""Fin de Siécle - 19th century"". In that sense this project was be a coninuation of this cooperation. Having started our cooperation in an excellent way we'd like to keep our international friendship and cooperation going. Comparing conditions in other countries and getting to know differences creates open mindes at our pupils. They are interested in new and unknown issues and their feeling for tolerance will enlarge. We are glad that we have got a further porject"
