Everything is perfect. I just have to vary point 1. I included a further point for you to check. Thank you very much. I think we have to vary some of the sentences.

1) Involvement of the classes of the participating students (Only 10 students belonging to current second classes participate in the project but they will also involve the class to which they belong)
2) Sharing of the results and the experiences with their classmates and with other classes involved in investigating works (activities??) on the environment.
3) Involvement of the municipalities, of the territorial structures (the Municipality of Alba, the region Piedmont, the Province of Cuneo, laboratories of environmental education (??)
4) Refresher courses for both teachers of other local schools (or schools in the area) and for the parents.
5) Promotion of the activities from the students on the school’s websites, the press and local sites (places??)
