Análise de rótulos de suplementos alimentares em aulas de Química: uma atividade de ensino de CTS
Abstract
This work presents a STS teaching activity, where food supplement labels were analyzed, with the aim of assisting the teacher in the task of invigorating or renewing his knowledge about chemical topics and their relationship with the Chemical-Health-Society trinomial. The work was developed with 74 students of the third grade of high school, of a public school in the municipality of Mesquita (RJ). Wrong student perceptions about dietary supplements were observed, which allowed possibilities of mediation between school knowledge and student knowledge, with new meanings to Chemistry in the life of the students participating in the research. Addressing the topic of food supplements in chemistry classes, establishes a relationship between Chemistry and Health, and allows students to reflect on the risks involved in the consumption of dietary supplements without professional guidance, in addition to a critical look at the trade of these substances, with economic and ethical aspects.
