Communicating astroparticle physics with the public

The Pierre Auger Observatory has developed various activities along the last year in the field of education and dissemination of astrophysics and high-energy astroparticle physics. Since 1999 different approaches and improvements of the tools used to explain what cosmic rays are have been implemented, tested, and redesigned based on public feedback in its headquarters in Malargüe city. This presentation highlights the Observatory's engagement with the community, focusing on the new initiatives. The open data policy, master classes for middle-level students and teachers, the design of innovative activities that involve the community, and the presence of the Observatory in special events with the participation of students are also described.
