A utilização da temática frutas para o ensino de funções orgânicas oxigenadas e nitrogenadas no ensino médio.

Abstract

Fruits, foods present in the daily lives of the population, contain vitamins and other compounds with diverse organic functions that help to fight many diseases efficiently. A recommended diet would be the daily consumption of at least five types of fruits of varying colors, thus enabling access to a greater variety of substances important to the organism. In this way, the Fruits Thematic was used as a teaching tool due to the properties beneficial to the health and by the diverse Oxygenated and Nitrogenated functional groups present in the chemical structures of its main constituents. In this work, a different approach was proposed to the Content of Oxygenated and Nitrogenated Organic Functions contextualized with the Fruits Thematic. The research was carried out in a public school in Pentecoste–CE, aiming to contribute to the learning of the students of the last year of high school, in relation to the proposed theme. The study was developed through a cycle of five classes, discussions and application of two questionnaires. The first one had the objective of ascertaining the previous knowledge of the students with respect to the proposed theme and the second one to analyze the acquired knowledge. An experiment was also carried out to determine the presence of vitamin C in natural and synthetic fruit juices. The analysis of the results of the applied questionnaires as well as the activity carried out revealed that the use of a theme present in the habits and customs of the students favors a better understanding of the contents in the Chemistry classes and contributes to the formation of conscious citizens capable of taking position regarding their eating habits.
