Practitioners of responsible science communication in Latin American countries face context-dependent challenges ranging from high poverty and inequality to a public from an extremely varied palette of cultural backgrounds. Effort has been done in the region to foster a coherent community of science communicators. This article reflects on the history of science communication in Latin America and how these challenges are being faced.

In this “practice insight” we present a series of experiences run by Association Traces, injecting participatory approaches into science engagement activities by valuing the knowledge of the public rather than focusing on their ignorance. Starting from the observation that a sort of hybridization is occurring between cultural activities and public engagement with science on one side, and co-creation and participatory activities on the other, we provide some insight on the features of each approach. Examples are then used to highlight the potential value of this hybridization: as a way of making participatory activity more recognizable and accessible to a wide audience; to ensure that scientists have a professional interest in engaging in the communication activity; to raise a sense of ownership and empowerment in the audience, etc. These examples will eventually show that participation may lead to science communication practices that are socially-inclusive and/or productive for research, and ideally both.

Science centers are seen as places for communication of science very focused on the mise en scène of the content and methodologies of natural sciences. However, in the recent history, these institutions are transforming their role within education and transformation processes in the society they are engaged with. This communication presents a social project in Medellín, Colombia, that involves a vulnerable community, the local authorities of the city, academic institutions and NGO’s and a science center that is neighbor to this community.
