O caminho da eletricidade: da usina eólica às residências

Abstract

The choice of this theme is associated with the fact that it is possible to demonstrate the form of energy production through a wind turbine without the need to go to a wind farm, just using a miniature model or even the experimental knowledge of energy transformation itself. In the pedagogical environment, it becomes a research resource that leads the student to think and put into practice the theoretical knowledge worked on throughout their academic training, comparing theory with practice. Therefore, our main objective is to understand the process of energy production through a wind turbine. To do so, it is necessary to describe how electricity is “created”, showing the transformation of mechanical energy into electrical energy, and then understand the operation of a wind turbine demonstrating how electricity is produced by it, and only then, sketching the path of electricity to homes. The present study is characterized as an exploratory research of the qualitative and quantitative type, as there was an interest in verifying the students' level of knowledge regarding the topic covered in the research. Consequently, by using experimental resources, it allowed students to interact, analyze and raise hypotheses around the entire process necessary to produce electricity from wind, from the transformation of mechanical energy into electrical energy to its destination, homes. When using the resources involved in this research it was clear that student participation was greater, just as the experiments were used, highlighting the effectiveness of theoretical-practical teaching.
