Item A experimentação no ensino de Química: análise de uma proposta de sequência didática para o ensino do conteúdo de metais pesados(2024-09-27) Lima, Isabela Januario de; Silva, Suely Alves da; http://lattes.cnpq.br/3497194749381919Chemistry and the knowledge it provides are extremely important for humanity since its beginning. Learning it provides the students comprehension about the most variable chemical transformations that happen around us. Teaching Chemistry can be challenging for various teachers that have troubles in getting attention from its students for this science, since it has very abstract characteristics and of tough comprehension. In this regard, practical pedagogics are needed to help catch the students’ attention on this science, and one way of achieve that goal is by practical experiments. The general goal of this research was to analyze a didactical sequence utilizing the experimentation as a methodology strategy for the teaching about the Heavy Metals. The utilization of practical activities in the teaching of Chemistry shows as a good strategy to simplify and enthrall the students in the process of learning so that they can articulate the theoretical concepts with practical experiments. This research shows the analysis of a didactical sequence about of using practical experiments when teaching about Heavy Metals. It shows the benefits that practical activities brought while learning the subject, as well the development of scientific abilities. The acquired data were analyzed in an articulated way along with the authors of the theoretical foundation under a qualitative perspective. The tools utilized were two questionnaires, one applied before the experimental activity, and a problem situation to conclude activities carried out afterwards. The research brought many positive outcomes, as a bigger participation of the students and a better comprehension of the same about the Heavy Metals and their characteristics. The engagement and curiosity about this specific subject and about clothes questions that involves chemistry in the experimental part of this science. In conclusion the experiment is one strategy that provides an improvement in the process of teaching and contributes to a bigger engagement of the students in the class, stimulating the curiosity of this science.
