An eTwinning program on the area's river that has been successfully implemented by the Greek school in the past as well as teaching in the Greek language course on the need to protect the language and culture of Europe's smaller populations have been the reason for the design of the Erasmus+ program. The students of the Greek school and especially those who come from families with a different culture from the dominant one (students from immigrant families) showed enthusiasm for the implementation of the program and worked in cooperation with their classmates from the Turkish school (with whom they had previously implemented a common cultural program) to find partners through the eTwinning platform. In the selection of schools, efforts were made to cover different natural environments in Europe, different cultures and languages of populations that do not belong to the most culturally strong countries in Europe. Schools with a certain percentage of students from immigrant families were also preferred, in order to take advantage of the special cultural background of these students for the implementation of the program.After the group of partners has been appointed, students from all partners schools worked together for about four months to design the program under the guidance of their teachers. The objectives of the project concern:1. the study of the language, popular culture, literature and art of the countries participating in the program as well as the students of each local community who come from different cultural backgrounds,2. the study of the river/ lakeside natural environment,3. the study of the value of the river / lake for the local community of each area,4. the examination of the degree to which the development projects of the river / lake of each area are carried out in terms of sustainable development and protection of the natural environment.The implementation of the project will be carried out with the guidance of specialists in each professor's field and with the participation of parents and relatives of students. The aim of the activities is to highlight the particular cultural identity of the participants and, through the search for common elements, to address this peculiarity as part of the common European heritage. The program will be attended by 10 teachers from each school and the students of each school are interested in getting involved. Students' parents and relatives will also be assisted. Twenty-two students of each school will visit the other schools to collect the material necessary for the activities and present the work that will have been done. The activities to be implemented will concern:1. the study of the flora of each region and the creation of a phytology with samples of plants, flowers and herbs of each region.2. the communication with specialists involved in the protection of the natural environment as well as with representatives of companies operating in the area, 3. the writing of a common dictionary of the languages of students participating in the program, including words related to water,2. the writing of an anthology with legends, myths, literary works referring to the river / lake of the region,3. the creating of an album with folk art, paintings and river / lake-inspired sculptures,4. the collaborative writing of a common history and painting by the pupils themselves on the river / lake.Objective of activities with cultural content is to emphasize the common elements in the projects to be examined, so that pupils can understand the common origin or the mutual cultural influences between the nations of Europe. It is expected that these activities will recognize the value of the particular culture of each pupil and thus make it easier for them to join the school and local community. At the same time, the value of the common European heritage and the need to protect it will be highlighted as a means of ensuring the peaceful coexistence of Europe's nations whether they are members of the European Union or not.The publication of the results of the program and the material that will have been produced on the website of the program as well as the participating in activities and attending relevant cultural events of local people will extend the outcomes of the project out of school to the wider local community. Finally, the projects that will be produced can be enriched in the future after the completion of the program with new material that will add new pupils attending the school and coming from a different cultural environment as migration to European countries is strong and will result in more and more students from different cultural backgrounds attending European schools. This will extend the long-term benefits of the program in the future.
