The fourth project meeting was held in Samsun, Turkey from 2-9 October, 2011. This was the fourth meeting of the project, c students and teachers participating in other three project meetings that took place in Austria, Spain and Poland. The next visit will take place in Greece and the last project meeting will take place in Romania and the students and teachers of the "Spiru Haret" National Computer Science College are eager to host the foreign teachers and the students. For project meeting in Turkey, students and teachers have prepared activities related to environment pollution and traditions of each country. Each country had to prepare a presentation of folk traditions and the things that characterize it. Students prepared posters and collages that have shown the most important problems facing the environment, global warming and talked about the solutions that can be taken to save the environment. Also, each student had to make a costume from recycled materials. At the end of the meeting of the project, students and teachers have made an album with images suggestive in nature. We visited two great cities: Sinop and Amasya and we learnt many interesting things about the Turkish culture and civilization. The students were hosted by Turkish families and they became good friends. We were impressed by the Turkish hospitality.
