THE TEACHING OF ENVIRONMENTAL CHEMISTRY USING INVESTIGATIVE EXPERIMENTATION ON THE THEME OF WATER POLLUTION IN WELLS

Abstract

Given the difficulty of interacting theory with reality, it is important that the student understands Environmental Chemistry according to what is around him, so that there is meaningful learning. This article presents a teaching proposal through investigative experimentation with the objective of favoring learning in Environmental Chemistry on the theme of water pollution. The research was carried out at IFCE/Caucaia-CE, in the period of Feb. -Mai. 2024, with students in the 1st and 2nd year of high school. The methodology continued with the following meetings: diagnosis of prior knowledge; conceptualization of the theme; field activity and sample analysis; and perception of learning. The results obtained showed the construction of a low-cost and reusable well water collection kit. In addition, the analysis of previous knowledge using qualitative statistics (IRaMuTeQ Software) showed that the students have some knowledge on the subject. The evaluation of the perception of learning and experimentation showed that the technical and theoretical training given to students motivates and facilitates meaningful learning on the subject when related to the student's reality. In this context, applied experimentation in order to favor meaningful learning in the teaching of Environmental Chemistry is a great alternative and a great ally to make the teaching and learning of high school students from public/technical schools more attractive, effective and meaningful.
