Dissertação (Mestrado em Ensino de Física) - Universidade Federal de Alfenas, 2018.https://repositorio.unifal-mg.edu.br/handle/123456789/1347The purpose of the present work is to suggest a method of teaching the content of simple electrical circuits that involves, besides theory, a practical activity, which is the construction of a protoboard, where the student is the main protagonist of his searching for knowledge. It is also suggested the use of an electric circuit simulator as a pedagogical complement. The resistors used in this protoboard are referred to in this work as organic resistors, and it should be explained that this terminology refers to organic food elements, such as sausages, cucumbers, carrots, among others. The purpose of this proposal is to make sense of the symbols used in textbooks and fixation exercises and equations, while allowing the student to be surprised during non-predictable situations during the use of the experimental arrangement. be able to make measurements, propose and test hypotheses, and can, in a solid way, replace their common-sense knowledge with scientifically based knowledge, capable of bringing understanding to similar situations. The purpose of the project is to provide the student, both visually and quantitatively, with the means to observe and measure the effects of the association of resistors, and to compare the measures taken with the theory previously worked in the classroom. It is also possible to work on other concepts such as the Joule Effect, effects of the electric field and the linear dependence of the potential difference with the distance where the measurements are made, the effect of the short circuit on the electric current and the potential drop in the resistors and their direct effect on the brightness of the lamps, the cooking time of the sausages according to the type of lamp used, among other effects.application/pdfinfo:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nc-nd/4.0/Física – Estudo e ensinoCircuitos elétricosMedidas elétricas.CIENCIAS EXATAS E DA TERRA::ASTRONOMIAinfo:eu-repo/semantics/masterThesisCamps Rodríguez, Ihosvany
