"The goal of the project was to get pupils to meet around a technical project : the building of radio-controlled model solar cars, allowing students to participate, twice in a row, in the ""Solar Challenge"" race in Toulouse at the Cité de l'Espace. Being part of the solar challenge has allowed collaboration and exchange between the Italian and the French students. The Italian students took care of the electronic side : the photovoltaic panels. The students from Mirepoix carried out the mechanical part. The technical manufacturing gear available at the Mirepoix techical high school made it possible to use different processes and different materials to produce the entire mechanical part (the front and rear axles, the chassis, the steering), along with the electronic knowledge of the Garbin high school for the photovoltaic panels.From the first trip in Schio, the understanding was very good, and the involvement of all the students in the project could be noted. The teamwork was productive and the commitment to solve the technical problems and reach the same goal was shared. The two schools seem different but are actually similar in the ways they work.Thanks to the participation of the Garbin High School fashion class, the students were able to wear racing clothes in the ""Solar Challenge"" race that took place during the second trip.The aim of the second year was to deepen the knowledge of photovoltaic panels and to raise awareness about the importance of renewable sources of energy, but also, thanks to the participation of the marketing class of the Garbin high school, to introduce the students to marketing strategies and communication techniques around solar panels.The various initiatives and the notion of competing against other teams on the day of the race helped to develop a real team spirit which helped promote inclusion and improve everyone's self-esteem.We were only able to carry out 3 of the 4 planned trips, and in the second year, only a prototype of version 2 could be carried out due to the prolonged closure of the schools. However all the goals were achieved and we obtained 4 prizes due to our involvement in the ""Défis solaires"" (solar challenges) race including the ""ESPRIT D'EQUIPE"" (team spirit) prize. The students enjoyed representing their schools in a European project and were able to realize what an opportunity this represents on the human, technical, professional and cultural levels. The students, who are preparing a technical college baccalaureate, finished the project feeling confident and grown up. They have been allowed to develop personal, interpersonal and intercultural skills, since they stayed at their penpals' homes. Meeting others was thus an opportunity to create lasting and sincere friendships."
