Biodiesel na escola: uma ferramenta para o ensino de química.

Abstract

The present work proposed a contextualized methodological approach to learning organic functions, physical and environmental chemistry, using the production of biodiesel from the viscera of Nile Tilapia as generator theme. The study was performed at the Henrique Jorge School, private institution in Fortaleza city, with 13 students of third year of high school. The methodology consisted of five stages: previous conceptions of students about biofuels through a investigative questionnaire, organization of knowledge from the theoretical class, study of the text about biodiesel production from fish oil, experimental activity of biodiesel reaction in order to complement the teaching-learning process and diagnostic questionnaire to evaluate the degree of learning and motivation in the development of activities. As result, highlight the positive assimilation of the content and classification of classes as great. The approach of themes linked with student's daily life besides contributing in building the knowledge and training of qualified and critical citizens, can improve and facilitate the assimilation of chemistry content.
