This article aimed to analyze ways of thinking about the concept of substance mobilized in the speech of two science teachers from the 9th grade of elementary school from two public schools in São Raimundo Nonato-PI. Therefore, we are guided by the theory of conceptual profiles that discuss the plurality of meanings that a given scientific concept can present, more specifically the concept of substance, since its understanding is very important for students' learning and for the understanding of others. chemical concepts. This research was carried out in two stages. In the first stage, a questionnaire was applied to trace the professional profile of teachers and map the main concepts used for the concept at hand. The second stage corresponded to the observation of three classes on the concept of substance and its applications taught by the research subjects, which were recorded with the aid of audiovisual equipment. Thus, the results showed a polysemy of concepts about substance, emerging in the speeches of the two investigated teachers and, thus, we found that they use in their answers various ways of thinking about this concept, whether a more formal language, a scientific one, or a way of think simpler, everyday language. With this, we realize that scientifically accepted concepts are not always used at school to introduce students to a certain scientific term, such as chemical substance, but it is noteworthy that every form of thought must be considered, as they contribute to the construction of new forms of meanings.
