We investigated the Physical Sciences in the Agricultural Families Schools considering the Pedagogy of the Alternation. In this sense, we take into account the lessons of Ethnophysics that seeks to comprehend, from the own social groups, their world view to be presented the physical academic knowledge. We use field trips, staying in school for three days to start the research process. The results show that the philosophical underpinnings of the PA are not well settled and the transdisciplinarity still not processed properly. Publication Name: Caderno Multidisciplinar da RESAB.
