Concepções sobre as condições ideais de consumo de água: contribuições para o ensino de biologia

Abstract

Water is constituted as an invaluable asset, due to several factors of a biological nature, which justifies an approach regarding its quality and forms of treatment in the school environment, an investigative methodology that contributes to the formation of a conscious and critical student, capable of making the citizen capable of taking decisions on issues involving science, technology and the environment. The objective of this work is to verify the contributions of the application of an investigative sequence (SEI) with the theme of water for the teaching of Biology in a school in the Municipality of Teresina. The proposal of the work will be an application of an investigative sequence that will have water as its theme and will take place through the following steps: elaboration of conceptual maps, an essay on the physical characteristics of water, an essay on the solubility of water, and finally a microbiological analysis of school water. Through the application of the SEI, its potential to place the student as an active being, protagonist regarding the construction of concepts inherent to the water treatment process and microbiological analysis, such as: solute, solvent, dissolution, polarity, coliforms, among others, became evident. The promotion of a horizontal relationship between teacher and student was also a notable contribution to making the classroom environment conducive to learning, in addition to raising students' awareness of environmental issues and developing the critical aspect and scientific literacy regarding issues involving science, technology and the environment. Despite advances in the aforementioned indicators that contribute to the construction of significant knowledge on the water theme, there is still a lot to advance in terms of breaking traditional educational paradigms, as there is still a lot of resistance to changes on the part of students, given the difficulties inherent in the lack of reading and interpretation, exacerbated use of memorization, apathy and lack of motivation by a large portion of the students.
