On April 7, the Olympic Stadium Lluís Companys hosted the day Visions - STEAM Anella. The Olympic Stadium became a center of experimentation where 1,525 students of 2nd and 3rd ESO could perform activities associated with STEAM culture (Science, Technology, Engineering, Arts and Mathematics). The project, jointly organized by Barcelona de Serveis Municipals (B:SM) and the School of Engineering of Barcelona Est (EEBE) of the Polytechnic University of Catalonia - BarcelonaTech (UPC) aims to promote scientific vocations among teenagers.

In addition, it seeks to break stereotypes and promote scientific vocations among girls, highlighting female scientific references. The project aims to provide students with knowledge through playful experiments. The subjects chosen are those which, due to their complexity, are more difficult to deal with in the classroom, in order to approach them in a flexible and creative way, while maintaining all the academic rigor.
