The students between 9 and 11 years participate in this category building their own car, in the subjects of Arts and Science, both of them taught in english. For that purpose they have a construction kit with instructions to follow. They design the bodywork with simple, affordable, easy to manipulate and recyclable materials. Teachers guide them under certain circumstances but students by themselves will have to organize and take decisions. We give awareness to the students about respect to others and their ideas and respect for the environment.
