Lixo e tempo de degradação : discussões no ensino de Ciências envolvendo PIBID e alunos da EMEB Jardim Paraíso de Sinop (MT)

Abstract

The human development brings waste production, which its accumulate are cause of concerns, primarily when it will not more be reused. In this perspective, with the help of students the Institutional Program Bags of Initiation to Teaching (PIBID), it was decided to focus on the theme “How much time is required for the complete decomposition of solid waste found in school garbage?” performing an experiment stimulating the change of attitudes and habits, providing a reflection about the consumption and the correct destination of school wastes of the 6th year students by the Basic Municipal School Paradise Garden, in the Sinop (MT) city. The study was introduced from a retrospective about the waste and an observation activity was proposed in the trash cans of several places of the school, so that, it was possible to verify the amount of waste accumulation daily in the school. The students noted down what was in each trash can, so that, in the classroom, a classification of the materials was done by using a spread sheet to check the degradation time of each one material. Following the activities, it was carried out an experiment with thirty days duration to be closed. The activities were ended up with an educational game application about the preservation of the environment called “Reciclino”. It was recorded that the solid waste decomposition produce fragments that can bring negative impacts in the urban environments, in addition, it is important to emphasize that it is possible to carry out experiments by using low cost materials, contributing to the development of student learning.
