Práticas experimentais na produção de bioplásticos no ensino de química: reflexões sobre sustentabilidade e meio ambiente

Abstract

This final course work (TCC) proposed a different approach to teaching Chemistry through the experimental production of bioplastics, focusing on environmental education and sustainability. Plastics (synthetic polymers) are widely used in daily life but often pose environmental problems due to excessive use and improper disposal. Thus, this research aimed to propose the production of bioplastics through investigative experimental activities. The study is qualitative and exploratory in nature and was developed with high school seniors (3rd year) at Centro Educa Mais Maria José Aragão in São Luís, Maranhão, Brazil. It integrated theoretical and practical activities on natural and synthetic polymers. Through lectures and hands-on experiments, students produced bioplastics using potato and industrialized corn starch, applying scientific concepts in a contextualized manner. Biodegradation tests were also conducted in different environments (water, sand, and soil), demonstrating the ecological viability of the bioplastics. The results highlighted the pedagogical potential of the approach, fostering student engagement, environmental awareness, and the development of sustainable practices in the school context. The initiative reaffirms the role of schools in shaping critical citizens committed to environmental preservation
