Da merenda ao biogás: desvendando a sustentabilidade na escola com decomposição criativa

Abstract

Numerous challenges arise throughout the teaching process, and student demotivation is observed when education professionals adopt traditional teaching methods as guiding principles. Therefore, it is necessary to seek alternatives that enable a comprehensive, student-centered scientific education. In this sense, the present study aimed to develop a didactic sequence designed to facilitate the execution of investigative activities through the construction of a biodigester. The goal was to explore sustainability concepts in high school, focusing on the reuse of organic matter with the potential production of biogas after the decomposition process. This didactic sequence was implemented with students in the final stage of high school in the Youth and Adult Education modality, spanning seven sessions/classes, each lasting fifty minutes. Throughout its implementation, a kind of "logbook" was produced to record curiosities, questions, and doubts that arose during its development. At the end of the activity, a qualitative analysis was conducted, considering observations and experiences throughout the process. An improvement in students' understanding of sustainability and the decomposition of organic waste was evident. The students' interest and satisfaction indicate the relevance of incorporating more practical and investigative activities in the educational environment. Additionally, there is a recognition of the importance of integrating more specific activities for developing research skills and data collection into the school curriculum. In summary, this proposal successfully achieved its objectives, providing students with a practical and meaningful experience in the realm of sustainability. It also paved the way for future innovative and interdisciplinary approaches in high school Biology education
