Abordagem dos conceitos de acidez e basicidade no ensino de química utilizando os produtos de limpeza como tema

Abstract

Due to the challenges high school students face in grasping chemical concepts, which are often perceived as abstract and distant from their reality, this study sought to create an activity manual that would address the concepts of acidity and basicity by contextualizing them with cleaning products. This topic is familiar to students' daily lives, making it possible to teach chemistry in a more accessible way. The manual proposes two activities that use videos, investigative experiments, images, discussions, and mind maps as teaching resources to connect theory and practice. The proposal is based on three pedagogical moments (problematization, organization of knowledge, and application) that stimulate critical thinking, autonomy, and active participation among students. These strategies promote meaningful, collaborative, and contextualized learning. Thus, the work not only sought to facilitate understanding of the chemical content, but also to contribute to forming more reflective, conscious students who are prepared to address chemical issues in their daily lives.
