In the context of the widespread reach of platforms such as YouTube, we study how identity-related issues shape the relationship between content creators and audiences, contributing to either the expansion or limitation of engagement with science-related videos published on Brazilian YouTube. To this end, we examine the argument that gender, race, and age are key factors structuring the dynamics of visibility, recognition, power, and the circulation of meaning. Our corpus consisted of 134 videos published on Brazilian YouTube. The findings show that identity functions as a mechanism of inclusion and exclusion in occupying positions of influence on platforms such as YouTube.

Recycling detectives is an intergenerational educational activity offered by the children’s area at Universum, the Science Museum of the National Autonomous University of Mexico (UNAM), designed to teach children and their families about the recycling process for Tetra Pak® containers. This text describes the pedagogical criteria that guided its design and presents the results of a formative evaluation based on direct observation to analyze interactions, emotions, and knowledge gained during the experience. The findings show that play, as a legitimate form of learning, facilitates intergenerational cooperation, stimulates emotions, and promotes environmental thinking from an early age.
