A temática da biodiversidade aquática através da experimentação: uma estratégia potencializadora da aprendizagem no ensino fundamental

Abstract

This work discuss with the theme of biodiversity, more precisely, aquatic biodiversity and its locus in science education. The importance of studying this theme emerges at a time when environmental preservation and the challenges that surround it, are aspects considered essential to the awareness of all who are committed to the educational processes. Given the disturbing environmental problems that severely affect the planet, discussions about them become especially important from the perspective of science education. In this sense, it is inferred that educational institutions are fundamental places for the construction of knowledge and the development of projects directed to the understanding of biodiversity and actions aimed at sustainability. The objective of the present research was to investigate pedagogical proposals focused on the theme of Biodiversity, and in detail, the Biodiversity of water, together with the elaboration of a sequence of activities related to the theme in elementary school. The methodological procedures adopted in the present work refer to a qualitative and quantitative approach, considered its descriptive-exploratory research. In this context, bibliographical and documentary research are complemented by a sequence of activities. Guided by the theme of aquatic biodiversity, it was implemented in a sixth grade elementary school of a state school in Caçapava do Sul, RS. Using experimentation as a methodology to enhance scientific knowledge, activities involving observation, hypothesis creation and visualization in magnifying and microscopes were developed. As a result it was found that students have a limited view of the aquatic environments and all the diversity of living beings that inhabit it. It was also possible to infer that a representative percentage of students perceive the influence of human actions with regard to environmental preservation. The research allowed us to observe that the group participating in the sequence of activities expressed attitudes of enthusiasm and interest in the course of practice, in a space characterized by a scientific view of the world. It is noteworthy that the students presented along the implementation of the sequence of activities, an evolution in the understanding of scientific concepts, which, in previous analyzes were often decontextualized, in addition to an improvement of investigative skills.
