O plástico doméstico na produção de material didático para o ensino de ciências

Abstract

Plastic is a material widely used by humans in various sectors and for the most varied purposes possible in society. However, durability, the main property of most polymers, is a major problem for modern humans, since these plastics do not decompose for hundreds of years and are composed mainly of synthetic polymers, which can cause environmental problems and imbalances such as pollution of rivers, seas, death of aquatic animals, etc. The use/reuse of these materials as teaching models is a possibility of reusing these materials, thus, the present work aimed to produce teaching materials on external leaf morphology, from household plastics, for students of Basic Education. The approach is qualitative and a cross-sectional study was carried out. In this context, 23 types of leaf morphologies of different profiles were developed, from plastic bags, the thermoplastic low-density polyethylene. The use of high-quality teaching materials in teaching can facilitate students' understanding of the topic of leaf morphology. These visual and conceptual resources make classes more attractive, encouraging active student participation and transforming them into protagonists of their own learning process. The importance of implementing methodological innovations in the educational system, such as the development of new teaching materials, is evident, so that students can experience educational practices that stimulate their participation and critical development, thus promoting their autonomy and adapting teaching to the needs of contemporary society.
