O uso de atividades lúdicas em uma abordagem contextualizada referente a metais pesados em equipamentos eletrônicos e eletroeletrônicos em turmas do EJA

Abstract

In Chemistry, the term heavy metal refers to a certain type of chemical element, as they have toxic effects for humans. In the homes of the majority of the population there are several pieces of equipment that contain heavy metals in their composition, such as televisions, cell phones, and many other electronic and electronic devices, which also generate the consumption of batteries. Heavy metals are a subject that has been approached with great importance in high school and it is a subject that brings with it knowledge. There is a need to talk about chemistry education, prioritizing the teaching-learning process in a contextualized way. The general objective of this research is to analyze the students' knowledge regarding heavy metals in electronic and electronic equipment. The specific objectives require contextualizing heavy metals in electronic devices to expand students' knowledge, determine through these activities the electronic devices and heavy metals that pose risks to human and environmental health, as well as discuss the use of recreational activities as a new methodology. The present work evaluated the role of recreational activities such as crosswords and word searches in the teaching of Chemistry in 1st year EJA classes at CEEP Rural Deputado Ribeiro Magalhães in the municipality of Cocal Piauí, in which it was possible to identify, through questionnaires, prior knowledge and acquired by the students and that the use of this methodology was able to draw more attention from them when approaching the contents in the classroom
