Atividades experimentais com materiais acessíveis no ensino de química: uma análise das percepções dos alunos de ensino médio

Abstract

The present work aims to explore the importance of experimental classes in teaching Chemistry, using experiments with low-cost materials as effective pedagogical resources. The main objective was to evaluate the impact of experimental activities on the teaching-learning process, checking whether these experiments aroused students' interest and contributed to a better understanding of chemical content. The research was carried out in two 1st year high school classes at an Integral Citizen School, during practical classes. These classes were carefully structured in several stages: introduction of theoretical content, development of practical experiments using household utensils and accessible materials, and assessment of student learning through surveys and qualitative questionnaires. The results indicated that the use of experimental activities with low-cost materials enabled greater student participation, facilitating the understanding of the concepts covered in the classroom and promoting the development of investigative skills and critical thinking. The approach adopted proved to be effective, promoting more inclusive, interactive and engaging Chemistry teaching, in addition to contributing to the formation of citizens who are better prepared to face contemporary scientific challenges.
