The STEM methodology applies the discovery-expanding learning where the student co-creates and co-operates with his classmates to provide solutions to educational problems, which relate to everyday life. This way exploration, inspiration, experimentation and creation take place in the problem solving process and the four pillars of STEM, Science, Technology, Engineering and Mathematics are exploited, highlighting the relationship of science to each other and approaching the problem holistically. This project will try to engage students with the STEM methodology and contact with the culture of European countries.
