14 students of 6H named Les Bacol'eau took 12 challenges during the school year with their teacher Audrey Théoduloz from Vex (in Valais) and her colleague. They managed to save 1238 m3 of water thanks to their actions. They sensitized the other classes and showed the people of Vex all the work done during their water festival. The 13 written articles and their presentation demonstrated to the jury the quality, intensity and pleasure that these students had with the programme. They also thanked their teacher warmly for allowing them to work with this programme. Thank you to them for their enthusiasm and thank you to the two teachers for their investment remarquable and noticed!
