Contextualização do biodiesel na aprendizagem de funções orgânicas e reações de transesterificação na disciplina de química

Abstract

This work makes use of the contextualization of biodiesel use, developed in seven strategic stages inserted in the organic chemistry contents of organic function nomenclature and esterification reactions, being applied to 27 students of the 3rd grade of a private school. With the increase in energy consumption coupled with population growth, there is an expansion of agribusiness and industry in the country, to meet food and energy needs. Renewable energy sources play a key role in the country's energy, environmental and socioeconomic context. During the application of the classes, there was great interest and participation in the production of biodiesel in the steps that involved the chemistry laboratory, in research that involved the production of material and exposure at the science fair, providing a process of collective learning in the search for new knowledges. Through application of evaluation, it was observed great performance of students in the use of the proposed methodology.
