Proposta de sequência didática para o ensino médio: o biodiesel e jogos educacionais

Abstract

The environmental impacts caused by the burning of fossil fuels is a current topic in High School. Another topic that is much discussed is the question of exhaustible resources for obtaining oil, since this product comes from a non-renewable source. In this context, research on alternative fuels has grown considerably. Among them, biodiesel has been highlighting the world scenario, becoming increasingly important its insertion in the school curriculum. This study approaches the application of the biodiesel theme in a contextualized classroom setting, with theoretical classes, didactic games, and experimental classes. The didactic activities involved the contents, such as: separation of mixtures, oxygenated organic functions, main reactions of carboxylic acids, density, among others. Two games were adapted: a trail game and a crossed game (crossed biodiesel) with questions and answers about the theme having as target group two classes of the 3rd year of High School of Olivina Olívia School. This methodology sought to highlight the role of chemistry as a science, transposing barriers and obstacles towards meaningful learning, promoting the formation of young people more aware oftherealityinwhichtheyliveandabletoapplytheknowledgeacquiredintheirdailylivesas citizens. The application of the project through questionnaires related to biodiesel improved the performance of the evaluated groups, and the group E presented better performance in relation to the group G. In general, the work with thematic projects in the school proved an efficient and consistent methodology.
