Project based activities are a good way to expose secondary school students to more science and math at earlier grades. In the last few years has been a decrease of enrolment for engineering programs in Spain. For this reason, the University of Girona (UdG), the Social Council of UdG and the Catalan Government started initiatives, with the aim of increasing the interest of students for technology and promote engineering skills, capabilities and values. These institutions support and promote scientific and technological activities of recreational nature that are attractive for students.
