Eletricidade e a construção de pilhas

Abstract

The discovery of electricity may be controversial, but the most widely accepted is that in Ancient Greece, when the philosopher Thales of Miletus, after discovering a petrified fossil plant resin called amber (elektron in Greek), rubbed it with skin and wool from animals and could then observe their power to attract light objects. Since then, electrical knowledge has gained great conceptual, physical, philosophical and historical wealth. Exploring such issues in the classroom, whether through experiments or historical approaches, brings us beyond conceptual issues, discussions that enrich the understanding of not only the development of physics, but the very way we live today. Following this line of reasoning, the present work aims to propose an investigative didactic sequence, bringing the history of electricity and experimental activities to deepen concepts such as what is electricity and chemical batteries, pointing out experiments such as that of Benjamin Franklin and his kite. A literature review on the teaching of electricity is carried out through the National Symposia on Physics, in the versions of the meeting between the years 2007 to 2020, the last thirteen years, such an event promoted every two years by the Brazilian Society of Physics (SBF), and its audience are Physics teachers of different levels.
