In the same way these proposals form directed to the executive and too much involved agencies in question of the local environment. FINAL CONSIDERAE: When if it considered to work the subject separation of Mixtures with the educandos, exactly the work possessing an objective clearly, had been appearing new perspective investigations and of research and action. The most important in this everything is that they had been the educandos that had given to the developed work a more including character, something that was not limited to the classroom. The taken positions and conclusions had broken of the comments and constataes verified for them in set with the professor.
The city of Aragominas was perceived that although to be an just-emancipated city, it faces serious problems in relation to the preservation of waters of its patrimony. The streams that circulate the special city in the Jenipapo stream and of the Field, are practically deceased, therefore the amount of life in existing them was evidenced that, is well lesser that, for example, has two decades and this was proven through stories of inhabitants and for what was verified in these streams during the research. It was also observed that the problem of the possible contamination of these waters is well more complex of what it imagined, therefore if sorna to this the problem of the played garbage the sky opened in places without no program of control and worse, next to the stream bed to these streams. Perhaps one of the conclusions most important has been the fact of the educandos to have detected the lack of planning since the first managers of the city for the question of the garbage and pollution of the water, then of the environment and that the solution for the problem cannot be decided only by the public power, but, for a work in set with the community. It is given credit that by means of the investigations, questionings and positionings front to the problem of the considered water inside of the subject Separation of Mixtures, the educandos had been capable to develop and to construct of certain forms the knowledge, therefore, had started to possess a critical conscience of the way where they are inserted, beyond exerting its citizenship, contributing for the construction of a more democratic society inside of its social aspects of changes.
