STSE (Science, Technology, Society and Environment), Printed circuit boards (PCB), Oxyreduction reactions, Science teaching, Science education.Abstract
The contextualization of experimental activities based on the inclusion of students' daily lives and CTSA content provides a broader view of chemical phenomena, re-signifying the role of the school for society, giving meaning to experimental activities and scientific content, contributing to the learning of scientific content and to the students' civic education, so this article aims to present an activity for teaching oxidation-reduction reactions under a CTSA approach with the theme PCBs (Printed Circuit Boards). In other words, the students built a PCB and were given CTSA content about the extraction of metals and the disposal of electronic equipment. This activity was part of the teaching project: "Experimental activities: science and technology in everyday life" developed at the IFPR - Barracão Campus.
