Petróleo, biocombustíveis, ambiente e desenvolvimento sustentável em Mato Grosso via ensino de Ciências

Abstract

The awakening of the necessity of a knowledge basis on topics related to renewable resources of energy is growing in the academy, as on the minimization of the environmental impacts and sustainable development, in the series of secondary level. In the fundamental level, the employed books take into account the topics of energy transformation, specifically related to the efficiency of thermal machines, disregarding the environmental impacts due to the combustible burning. On this subject, the books show that the residual energy is lost as heat dissipation. So, on the point of view of the learners, this king of energy fades away without other consequences. Therefore, in this work, a teaching product was developed, both in press and digital version, focusing in the energy resources and the different kind of fossil and natural combustibles, also in the carbon dioxide production and other gases related to the greenhouse effect and acid rain. This material was constructed on the basis of the Critical Meaningful Learning Theory and the Thermodynamic laws. It was treated subjects as the ethanol and biodiesel production, combustion heat, and the energy transformation in Otto and Diesel motors. It was expected that the students learning lead to the formation of competent professionals on this subjects. The teaching product is available as a complementary material to teachers in the André Avelino Ribeiro State School, local where the author works. The results of this work showed that the material has a good potential to contribute with the meaningful learning of these topics. The author believe that the improvement of the science teaching quality, particularly on the subjects treated in this work, can contribute significantly to the generation of professionals of better profile in order to develop and use kinds of energy more adequate to the MatoGrosso state.
