[Interactive and conversational experiences of visiting families in "Darwin, the exhibition, exploring species," at the Museo Trompo Mágico, Mexico].

We analyzed the conversational content and interactions of ten families, with the aim of understanding the learning experience of families in a scientific exhibition. As instrument of analysis, it was used a protocol combining theoretical and empirical aspects of interactivity. The results show that the families actively participated in the exhibition, observing and talking about the animals, asking questions, looking for answers and elaborating explanations based on scientific thinking. The adults acted as facilitators of learning and for this they were supported by information panels promoting the connection with previous experiences. Children show curiosity, emotions and behaviors that evidence their learning experiences and interest in scientific topics.
