Abstract

The use of technological equipment has been growing gradually year by year. In this sense, it is noticeable that the increase in the use of notebooks, digital cameras, cell phones and other electronic devices tends to generate an increase in the production and consumption of batteries, which, with their incorrect disposal, can negatively affect the environment. and people's health due to the highly dangerous heavy metals contained in its composition. Faced with this serious and problematic issue, the school presents itself as a favorable environment for the development of educational activities focused on the theme of discarding batteries. In this way, the objective was to sensitize and make students of the 2nd year of high school aware of the harm caused to the environment by the incorrect disposal of batteries. The present work was developed at the Centro de Educação de Tempo Integral (CETI) Deputado Pinheiro Machado. The methodology used was qualitative and quantitative, in which an educational action was developed on the topic addressed to the students. This awareness raising action took place in seven stages: application of an initial questionnaire, analysis of the textbook, lecture, exhibition of an educational video, application of a didactic game, delivery of folders and application of a final questionnaire. The educational action carried out made it possible for the students to know better the problem of discarding batteries. Such action aroused the interest and curiosity of the students in relation to the proposed theme. Therefore, the students actively participated in all the activities developed in this work. Regarding the questionnaires applied before and after the activities, it was noted in the first questionnaire that the vast majority of students had no prior knowledge about the damage that improper disposal of batteries can cause to the environment and human health and proper disposal of these materials. After carrying out the activities, it was observed in the second questionnaire that the students acquired knowledge about the topics covered. Therefore, it was found that the educational activities developed are effective, as very satisfactory results were obtained with the performance of the activities.
