Descargas elétricas atmosféricas: uma proposta pedagógica para o ensino de eletrostática.

Abstract

The main objective of this work is to propose a didactic sequence that correlates Atmospheric Electrical Discharges with the Van de Graaff Experiment. The initial motivation for the elaboration of this work is given by the abundant presence of lightning incidences in the country, more specifically in the northern region where the school unit that contributed to the application of the Educational Product attached to this document is located. In the application of the Educational Product, an Investigative Teaching Sequence was used, applied in two classes of the 3rd Grade of High School, in the city of Miracema do Tocantins. If any teacher wants to use this methodology and the school unit does not have a Van de Graaff Generator available, in the Educational Product attached to this work, it proposes the assembly of the equipment. The main objective of this dissertation, in addition to teaching concepts of Electrostatics using active methodologies in order to provide students with greater interest in learning Physics, is to demystify mistaken concepts in relation to Electrical Discharges that are absorbed from indigenous cultures, which are quite present in northern regions of the country, including the city of Miracema do Tocantins, contributing to scientific literacy and provoking greater student interest in a career in science.
