Abordagem do efeito antioxidante da vitamina C a partir de atividades investigativas

Abstract

Electrochemistry contents explain several important phenomena and chemical processes. However, some researches shows that Electrochemistry contents are considered difficult and complex for teachers and students, making the teaching and learning process difficult. Considering the importance and complexity of teaching electrochemistry and the potential of the investigative approach, this paper presents the results of the application of an investigative didactic sequence about Electrochemistry contents for students of the second year of high school. In this paper we present the results and analysis of student responses to the phenomenon of food oxidation and the use of vitamin C (ascorbic acid) as an antioxidant. The results showed that investigative activities contribute to the learning of basic electrochemistry content and also make it possible to address relevant topics such as chemical additives.
