Contribuições das atividades experimentais com uso de materiais alternativos de baixo custo para construção do conhecimento químico: uma revisão da literatura

Abstract

This study aims to analyze the importance of experimental activities in chemistry education, focusing on the use of alternative low-cost materials as a strategy to overcome structural challenges, enabling the construction of chemical knowledge. The research is based on a bibliographic review of academic works that address this topic, seeking to understand how these practices contribute to the construction of scientific knowledge and student engagement. The methodology adopted consisted of a qualitative analysis of monographs available in repositories of universities and federal institutes, prioritizing publications between 2014 and 2024. The results demonstrate that the use of alternative materials in chemical experiments allows for a greater approximation between theory and practice, promoting more interactive and contextualized learning. In addition, experimentation with accessible resources favors the development of critical thinking, autonomy, and creativity in students, making classes more dynamic and stimulating. It was also observed that training teachers to implement these activities is essential to ensure their effectiveness, highlighting the need for educational policies that encourage the use of active methodologies in Chemistry teaching. It is concluded that experimentation using alternative materials represents a viable solution to expand access to practical teaching of Chemistry, especially in schools with limited infrastructure. This approach not only facilitates the assimilation of content, but also contributes to awakening interest in the subject and to the formation of citizens who are better prepared to understand and interpret everyday chemical phenomena.
