The superficial draining direct occurs of intent form in the urban space, whereas in the agricultural area he is diffuse, decentralized. In the cities this type of draining, beyond provoking the assoreamento of streams and rivers, also provokes clogging of galleries that promote the water concentration, provoking the floods. The disequilibrium all provokes also flooding and erosion of the edges of the rivers and slope fall raising still more the assoreamento (TUCCI, 2005). The process that takes of the urbanization until the damages and economic losses, if repeats all time that appears a new quarter. This if of the one in function of low the infiltration of waters and increase of the emanation. This situation is aggravated with the lack of education of the inhabitants of the cities that discard garbage in the public ways, of people who in search of materials you recycle open garbage bags and spread in the streets indesejado material, of the lack of appropriate places for discarding of resultant materials of reforms in the civil construction and other improper actions that do not condizem with the best forms of urban conviviality. This situation is aggravated with the lack of cleanness in the streets, with the habitacionais constructions, impactando urban pluvial waters with residues and other pollutants (SANCHES, 2006). Below the diagram of the urbanization and pluvial draining (SANCHES, 2006 P. 212; apud AMORIM, 2008) URBANIZATION - WATERPROOFING OF the GROUND - REDUCTION OF the TAX OF WATER INFILTRATION - FAST INCREASE OF the OUTFLOW OF the WATER COURSES - DAMAGES AND ECONOMIC LOSSES STUDY AREA: The quarter A.E.Carvalho City, is located in the zone east of S.Paulo, next to the quarter to Itaquera. The quarter is known...

Open Door As it was intended to work with a group of 4 year of basic education, with the intention of raising which physical concepts they are boarded in the education of Sciences, were carried through the analysis of some books used for the school. Among analyzed books we detach: (i) Learning always sciences (4 year) of the author Cristina Maria of the Wedge Fields, (II) Pitangu Project: Sciences (3 srie/4 year), (III) Open Door - Sciences (3 srie/4 year) of authors ngela Gil, Sueli Fanizzi. The didactic book used by the children also was, obviously, analyzed. Although the analysis has been superficial, since it was not the focus of this work, was perceived that the books approached many activities involving water and air, in Technological agreement with the PCN that point thematic blocks as Surrounding, Human being, Health, Resources, Land and Universe (BRAZIL, 1997). Other leaders such as Gina Bonati offer similar insights. In accordance with this document, the contents must favor the construction of a world vision, that if presents as a whole formed for interrelacionados elements, between which the man, transformation agent. The education of Natural Sciences must relate natural phenomena and objects of the technology, making possible the perception of a world permanently reelaborado, establishing relations between known and the stranger, the parts and all. (BRAZIL, 1997). Soon, they appear strong in didactic, topical books as water, air, energy among others contained in the thematic blocks, that can be worked of form diversified for better agreement of the pupils. Being thus, in the first chosen activity the subject was ' ' the problem of presso' ' , a content of the physics studied for the mechanic of fluid, that involves the understanding of that the pressure in the interior of a fluid in accordance with increases the increase...
