“There is no life without water. Water is a valuable resource that is essential for all human activity. Water knows no frontiers. It is a common asset that requires international cooperation." (European Water Charter of 1968) The rivers that flow through our cities connect us in Europe. Therefore, one goal of our project is to provide water as a connecting element (Water connects!), which is equally essential for all people around the world and throughout Europe. We need to value our water and protect it, we must not waste water. We want to use this project in order to increase awareness of the participating students and teachers, and to make aware the importance of water to the public. Our project extends over three years and includes 36 students and 6 teachers (per year) from Augsburg (Germany), Wageningen (NL) and Gödöllő (HU). The pupils are in grade 7 to 10 (13 to 16 years old), so they are at an age at which they are reflecting more and more about their future careers. In the first year of the project we want to consider the cultural and historical role of water for our cities. Participants will explore the role of water and waterways in the development of cities. Have the rivers changed geographically? Have the rivers been regulated? How was the water supply and the quality of drinking water in the past? How much water did the citizens need on the average? During the second year of the project we want to emphasize to the participants the importance of adequate hydration and to react to specific problems in our partner schools. We have found out that most of us think about a healthy diet, but rarely, we think about our drinking habits. We want to encourage students to critically examine the "water situation" in their schools. Is water wasted at our schools, for example, in the toilet rooms or in the course of preparing food? Do the schools support their students to drink enough, preferably water and not unhealthy drinks? How is the water quality in our schools? Is there a problem with garbage or plastic bottles that could be fixed? On the basis of the acquired knowledge students are encouraged to design a recyclable and durable water bottle in the third project year. This bottle can be purchased at the end of the project by all students of the three participating schools, thereby emphasizing the connection of our schools. In addition, this water bottle might help people to drink more healthy water, both in and out of school. For this purpose, project participants should develop concepts (bottle shape, material), get and compare offers, place orders and customize the product. This practical part will provide an important experience for the project participants, as they can put teaching skills into practice. At the end of the process, they can hold a product in their hands, which is their result of innovation and creativity, including entrepreneurship. The desired results are achieved by means of group work, independent student work under the guidance of experts, practical experimental learning, out-of-school learning, and through the work on multimedia presentations. The numerous presentations and continuous cooperation with partner schools help improving and intensifying language skills. We will ensure that all project results are available on the e-twinning platform. Our main product (water bottle with information sheet) and a summary of individual project results will also be published on the schools’ websites. Stands, posters, flyers, etc., will find a place in the schools after the public final exhibitions. The project material is adapted for use in the classrooms. Our project hopefully leads to encourage high-quality learning, which is needed to change students’ attitude towards water and to help them to become healthy responsible European citizens.
