Els alumnes han investigat i comunicat a companys d'altres cursos els seus resultats en diversos formats científics. L'experiència s'ha valorat com a molt positiva per a l'interès de l'alumnat en la ciència, el desenvolupament d'habilitats científiques i la difusió de diverses tipologies d'activitats competencials. Paraules clau: indagació, comunicació científica, context, competència científica The development of the scientific competence implies participating in first person in scientific communications and investigation activities. Here, we present an experience developed during 2013-2014 and 2014-2015 academic courses in the The Science Week in which science teachers and students from all courses from the high school INS Vilanova have participated. Students have investigated and communicated to mates from other courses their results in different scientific formats. The experience has been valued very positively due to the increase interest of students in science, the development of scientific abilities and the diffusion of different typologies of scientific activities.
