Uso de técnicas de desenho e animação para o ensino de química aos educandos indígenas fundamento no princípio de reações químicas do biodigestor

Abstract

The idea of developing a business with a focus on environmental education, and acquisition of clean energy sources and renewable energy sources, has emerged from a current issue of the society. The high rates of deforestation and environmental pollution associated with the rapid growth of technology and justify the importance of this theme generator. For this reason, the proposed work is to build a bio digester in order to use it as a teaching tool for the development of theoretical and practical classes of chemistry, with learner’s indigenous people of the second grade of high school. This teaching strategy aims to carry out discussions with learners indigenous to various sources of obtaining of clean energy, the use of organic compounds, reduction of dependence on fossil fuels, and deforestation. Other content to be explored in the discipline of chemistry are the phenomena that occur inside of the bio digester as a process of production of methane gas, the speed of the chemical reactions and different types of breaths. In order to meet these objectives will be built a bio digester didactic in scale, to represent the chemical phenomena that occur in the process of production of methane gas, the speed of the reactions. The aim is to awaken in educating its social and environmental responsibility, in addition to showing the importance of practical lessons and experimental in the aid of understanding the complex contents of the discipline of chemistry.
