Highlight ecological problems in our high school and in Reunion Island and present them in a video with possible solutions. Our students already spotted some problems : packagings pollution in the schoollyard and on the beaches of our island. Food wasting at the school canteen is another problem. Our students would like to shoot a movie (with time laps techniques) to show the other partners these problems. In a second time, they would like to shoot another movie to show all the ideas they have to improve things. The first task could be a mutual presentation of the students, their high schools, their countries. A second task could be a presentation of the problems they spotted and the solutions they imagined (videoconference, chat, email)… The final result would be a movie or a good quality Powerpoint presentation which would include all the partners' contributions.
