其他摘要：This paper presents a didactic sequence based on historical and philosophical approach, which aims to contribute to the teaching of the concept of air pressure and the insertion of discussions on nature of scientific knowledge in basic school. It takes into account the historical construction of this concept in activities that arouse critical thinking. Particularly, students are supposed to engage themselves in an "investigative" process of a given physical phenomenon. They are also supposed to confront their own conceptions to those arising from excerpts of historical sources properly contextualized. It is suggested a mediated intervention of dialogical character, organized in discussions on scientific contents and on nature of science.
