Resumo: Neste trabalho, descrevemos uma atividade associada a tematica biodiesel desenvolvida junto a uma turma de segundo ano do Ensino Tecnologico. O objetivo foi trabalhar alguns conceitos de Quimica Orgânica e a associacao desses com o meio ambiente ressaltando a discussao na producao de biocombustiveis. Buscamos como base para a metodologia de ensino os momentos pedagogicos propostos por Delizoicov e Angotti  (1991), por permitirem a realizacao de diferentes atividades. Para avaliar e validar esta pratica, foi aplicado um questionario ao final, atraves do qual pode se destacar que a proposta e uma interessante estrategia de ensino na aproximacao entre a ciencia e problemas sociais e ambientais.

Biodiesel: an experience from students of Technological Education Abstract: In this study, we describe an activity related to the biodiesel subject which was applied to a second year class of Technologial Education. The goal was to work on some Organic Chemistry’s concepts and its association to the environment emphasizing the discussion in the biodiesel production. We propose as teaching methodology the pedagogical moments proposed by Delizoicov & Angotti  (1991), which enable different activities to be done. A questionnaire at the end of the activity was filled out by the students in order to evaluate this approach, which validated the activities done as an excellent approach for teaching students to assign the science to the environment and social issues.
