Modelos no ensino de química : verificação do modelo termodinâmico do calor sensível

Abstract

Scientific modeling is a didactic tool to build models, and a didactic transposition can be made to be worked on in the classroom. The new changes in the paradigms of education, in the National Common Curricular Base, bring the search for investigative development in students, with the use of scientific modeling applied in teaching being a viable option that meets this new paradigm. In this context, this work aimed at the first part of a literature review on the use of scientific modeling in the teaching of Chemistry, in the second part it aimed at the validation of the theoretical model based on Mario Bunge's scientific modeling on the sensible heat equation, if it was directly proportional to mass, temperature variation and specific heat. The results obtained from the literature review show that there are still few works focused specifically on scientific modeling in classroom teaching, and of those that present this, most of them are in the area of physical chemistry and none of them uses Bunge modeling. Regarding the validation of the theoretical model, with the experimental data, the linear dependence of heat with the variation of temperature and mass was verified, but it was not possible to verify the linear dependence of the sensible heat with the specific heat.
