RESUMO

The first decade of the XXI century is over and now a new vision of the world rises. This new vision is based on the understanding that our natural resources will not last forever and also that the irresponsible use of those resources will have serious effects on life on earth. The present situation demands a change in the way we see social organizations. The main question now is how we should organize society in a way that we could be responsible for the environment, and still keep everyone satisfied. Getting the young students who will become the working force in the near future to know that they have to be responsible for the environment today is an excellent way to start. Energy supplies must be the main subject of discussion in any attempt to reorganize the way a society should work. Therefore, this thesis aims at developing a didactical material for high school teachers. The focus of this study is on the chemistry of fuels and how this particular subject can be taught in high school. The Brazilian energetic matrix uses 46% of its non renewable resources, a rate which is much higher than the one in most countries in the world, which is 12%. The recently discovered oil fields, in deeper layers of the Atlantic Ocean was also possible through academic researches. The development of the didactical material which is the object of the present project started with the analysis of the results found by Petrobras researchers on alcohol and oil and also with the analysis of the results of the researches led by the Chemistry Institute of UnB, which focus on the study of Biodiesel. The proposal was that both researches could be used as content for High School Chemistry teaching, according to Yves Chevallard`s Didactical Transportation theory.
