Feira de ciências “a física nas tecnologias sociais para a convivência com o semiárido”: uma sequência didática para o ensino sobre energias renováveis.

Abstract

Social technologies encompass solutions developed collectively—drawing on both scientific knowledge and local wisdom—that aim to foster sustainable development and improve quality of life in specific contexts, particularly in communities with limited infrastructure. These technologies are crucial in the Brazilian Semiarid region, an area characterized by socio-environmental challenges but also by richness and potential. Schools serve as a key venue for valuing and disseminating these social technologies, utilizing innovative, participatory approaches such as Project-Based Learning and science fairs. In this context, this study aimed to develop and implement—as an educational product—a teaching sequence for a science fair based on Project-Based Learning. Centered on the theme "Physics in Social Technologies for Living with the Semiarid," the project was carried out at the Teresinha Nunes Full-Time Educational Center (CETI) in Picos, Piauí. The research sought to understand how the development and dissemination of social technologies designed for life in the Semiarid region could be promoted through a science fair guided by physics education. The educational product was developed in stages—covering problem-posing, development, and synthesis—with the participation of 17 CETI students. Data collection involved participant observation, interviews, and questionnaires, yielding both qualitative and quantitative information. Qualitative data were subjected to thematic analysis. The findings indicate that the initiative contributed to innovative physics teaching and strengthened discussions regarding the importance of social technologies for sustainable living in the Semiarid region.
