Aplicação de práticas experimentais com enfoque em meio ambiente, conforme metodologia abordada por Oliveira e colaboradores (2010b)

Abstract

The objective of this study was to perform three experimental activities in the second year of high school in a public school in Marabá-PA, based on the methodology developed in the paper "Developing educational games for teaching chemistry" by Oliveira et al. (2010). The experiments referred to the following topics: acid rain, river pollution and decontamination of rivers, associating the concepts of chemistry with the environmental problem and its remediation through environmental education. The expressive results indicate that the use of experimental procedures based on demonstration, verification and investigation, are determinant for the evolution of chemistry classes. Finally, experimental practices when proposed and executed in a planned way constitute an exceptional didactic tool capable of assisting teachers in their classes, contributing to the awakening of students' interest in Chemistry and its implications on the environment.
