In Argentine institutes and scientific research centers, efforts are rarely dedicated to public science communication (PSC), which weakens the connection with the society to which they belong. For this reason, in 2015, the Institute of Limnology “Dr. Raúl A. Ringuelet” (La Plata, Buenos Aires, Argentina) created its Extension and Communication Area, which has coordinated numerous activities at science fairs, schools, and neighborhoods. Through the implementation of a relational approach, adaptable to similar institutions, solid connections have been established with various sectors, and the internal revaluation and enhancement of PSC.
