Studies in the field of science education have discussed using historical approaches. Although previous studies have shown the potential advantages to addressing national sciences in the classroom in countries underrepresented in the history of science, there are still few initiatives in this direction. Thus, this paper aims to explore a historical case study related to teaching Brazilian national science in a high school classroom to contribute to this line of research and evaluate how classroom dialogue and production relate to specific aspects of the historical case. The present study uses an adapted action research methodology with historical research conducted in an integrated manner with the case study in the classroom. The results showed that this adapted methodology could relate content to students' contexts by leading them to engage and identify with the historical case and the activity itself. Critical comments on this methodology are also presented. Using Brazilian science as the historical case study revealed some themes partially related to the Brazilian context. However, science content was more relevant to the students' context. Finally, some directions for future research are proposed, both for studies using the methodology presented and research on using the history of national sciences in countries underrepresented in the hegemonic history of science.
