O uso da massinha de modelar para ensino da lei de Ohm nos anos finais do ensino fundamental

Abstract

This study aimed to analyze the contributions of experimentation with electrical circuits using modeling clay to bridge theory and practice in Science teaching in the final years of Elementary School. The research was characterized as a qualitative-quantitative, descriptive, and bibliographic study and was conducted through a pedagogical intervention involving 30 eighth-grade students. Data were collected through a pre-test and a post-test consisting of ten multiple-choice questions, in addition to observations carried out during the experimental activity. The didactic sequence involved the construction of simple electrical circuits using modeling clay, a battery, conducting wires, and LEDs, aiming to promote the understanding of basic electricity concepts. The results showed an improvement in students' performance between the pre-test and the post-test, as well as greater participation in discussions, hypothesis formulation, and circuit construction. It is concluded that the use of low-cost materials associated with inquiry-based experimentation contributes to the understanding of electricity concepts and represents a viable alternative for Science teaching in different school contexts.
