Revisão bibliográfica sobre o uso de experimentos de baixo custo em eletricidade no ensino de física

Abstract

This article presents a literature review on the use of low-cost experiments in the teaching of electricity. The objective was to analyze the main methodologies found in the literature, the materials used to construct the experiments, and their potential for the teaching-learning process. The study is classified as bibliographic research with a qualitative approach and exploratory and descriptive objectives. Nineteen papers published between 2021 and 2026, selected from Google Scholar and SciELO, were analyzed. The results showed that low-cost experiments foster the integration of theory and practice, encourage active student participation, develop scientific thinking, and expand the possibilities for teaching electricity. It is concluded that these experiments represent an accessible and effective pedagogical strategy for physics education—particularly in schools with limited resources—promoting more meaningful learning and diversifying experimental practices within the school setting.
