Group 4 has been working about the impact of our schools in the environment. Firstly, national groups of students did a questionnaire to identify the strong points and the weaknesses of our schools and then, they prepared a power point and/or a video to present that information to the other partners on April 24th. Later, students worked in international groups to share ideas and make proposals to improve our schools for 2 weeks and made a final presentation on May 7th.
