The valuation and the deepening of the knowledge organized in the different ones you discipline pertaining to school are conditions to establish the relations interdisciplinares, understood as necessary for the understanding of the totality. Exactly when historical and cultural conditionings are gifts in the format of the educative system, they do not hinder the intention to search to transform the theory into practical aiming at the reinforcement of the learning. So that the scientific thought is incorporated by educating as one practical one of its daily one is necessary that Science is to its reach and the knowledge has felt and can be used in the understanding of the reality that the fence. The school has the responsibility to form conscientious, critical and active citizens in the society. The current Brazilian legislation for education it guides the schools in this direction. (BEVILACQUA & COUTINHO-SILVA). The satisfaction to come, to be in the school, of really learning is what it searchs with practical pertaining to school and more efficient learnings. One becomes necessary to make possible to the pupil one better accompaniment of the evolution of Science, of the transformations that occur in the nature and of the history of the man.

The base of the cultural formation of the children and young is molded in the school. The way that goes of the learning to its practical application passes for the development of abilities, the adoption of attitudes and the acquisition of abilities, that are the necessary mediaes in this process. Learning, … is the process by means of which educating interacts, it assimilates, it incorporates, it understands, it means and it dominates a content. It is treated, therefore, of an activity of interactive and buying nature. (COAST). The experiences in classroom are the mechanisms of perception and evidence of that what it is being studied it is of value, is real.

Not being plus no secret of that water, a hdrico resource that already comes suffering with the conscience lack, has gradual if depleting. The pollution of the rivers with innumerable not biodegradveis substances, the irresponsible consumption and without sustainable recital in the economic development are excellent factors in the process of reduction of the water.

Beyond the contamination of the water, the wastefulness exists that starts in the net of defective distribution and with the precarious maintenance and the use irrational domestic servant. An example is in the hour where if it goes to take bath: a on shower per 10 minutes spends about 160 liters of water, the double of the daily amount enough for a person to remain in satisfactory levels of health and hygiene. With so great wastefulness, one of the biggest problems is installed that are the scarcity of the water in all planet, together to a chaos that will be able to be installed in the humanity, since, without water, it does not have support. These situations are possible to occur in short term, therefore already countries exist that already pass for these problems, the example of Egypt, Israel, Saudi Arabia, Holland and Cingapura. In the last times never it was said in such a way in alerting and in educating the humanity to look at it stops backwards and taking off examples of its proper committed errors.

To study phenomena, the changes, the behaviors, or even though to be seen as the science of the beings livings creature, sciences, to be seen by some as only plus one discipline inserted in a resume of the schools. To think until point the education of sciences can go, and until where it is or it would be its delimitation, while theoretical lessons, while practical metodolgicas or even though innovations in the day-by-day pertaining to school one. Excellent, thus the education of sciences can be cited, a time that brings a more including dimension of what it is seen around and it allows that the pupil more than observes the universe based on a not passive process, but a dynamic process, a flow of knowledge of the process teach-learning that guarantees a critical formation, social and even though technological for the way in which the same is inserted. This process of learning of sciences does not have to be conditional more the one disciplines to be given, or plus a horria load to be fulfilled, but yes to reach a basic objective how much to the formation of the pupil as one to be integral, known as scientific alfabetizao that can be seen as the capacity to recognize formulas and to give correct definitions, until the agreement of the concepts and some degree of understanding on the social and historical nature of science and its dimensions. Based in this idea she is necessary to give an emphasis of that this must be a sufficiently significant concern during basic education, exactly that is important also for average education, and who exactly knows to extend to superior education. I defend that science is seen as a language; thus, to be alfabetizado scientifically is to possess subsidies become that it capable to read the language where the nature is written. Entering in a focada quarrel more to the praticidade of the education of sciences we must know what in they say concerning this official documents to them.

The neurnios are the responsible cells for the transmission of the nervous impulse in the animals. This is endowed with carcter electrochemical, for if considering that its transmission if processes electrically throughout the nervous cell, but chemically of neurnio for neurnio. The concept of sinapse to define the communication, strict of physiological nature is used, between two consecutive nervous cells, pondering the inexistence of an effective physical contact between two consecutive neurnios. Thus, in the membrane of axnio, in the region of telodendro, called membrane daily pay-sinptica, neurotransmitters are become free that, a time in the sinptica crack, stimulate the membrane of the dendrite of the following neurnio, that is, the membrane after-sinptica. By consequncia, in this neurnio, to the level of the membrane, its permeability to the caties is modified sodium and potassium. This alteration is expressed an inversion of the membrane potential that characterizes these cells in situation of rest, varying of – 70 mV for + 40 mV. In such a way, regista the development of a share potential that if propagates throughout the nervous cell, transmitting thus the impulse nervous.

(ROMANOWSK, 2007, p.52 and 53). Already in the years 70 with the Law of Lines of direction and Bases of National Education N. 5692/71, where still the tecnicista pedagogia pairava, the professor is considered as responsible technician for the planning of its lessons. In this context they used diverse materials, technological as in such a way audiovisuais, forgetting them artistic knowledge, leaving its pupils if to express of spontaneous form. In accordance with Ferraz & Fusari due: to the absence of theoretical bases more based, many they value proposals and activities of the didactic books, that in years 70/80, are in full marketing height, although its arguable quality while resource for improvement of the art concepts. (FERRAZ & FUSARI, 1993, p.32 e33). Between years 80 and 90, the pertaining to school education walks for a historical conception? critical, this pedagogia if worries about the access of basic knowledge of the art, that are necessary for one practical social transforming one, where: ' ' The historical conscience is the critical reflection on the concepts, the ideas and the educative actions of our time, making possible our contribution accomplish in the construction of practical and theories and theories of pertaining to school education in art ' ' (Ferraz & Fussari, 1993, p.36). In accordance with the Basic Resume for the public school of the state of the Paran (1990, p.52), ' ' the artistic activity does not have to be imitativa, however a creative assimilation that is made through the appropriation and of the rework of the knowledge artstico' '.

With Law 9394/96 the Art becomes area of the knowledge. In the National Curricular Parameters (1998, p.30), ' ' the artistic manifestation in common has with the other areas of knowledge a character of direction, creation and inovao' '. In the school, this knowledge in Art, the pupil must gradually it enters in contact with diverse artistic languages (Visual Arts, Dance, theater, Music).

For the action of the liver it balances the amount of plasmticos amino acids, synthecizing essential proteins, enzymes, lipoproteins and albumen. It converts acid the carbonic one of the amino acid into glucose. responsible for the synthesis of 95% of the urea.

The conservation of foods to usufruct of its nutrients is very important although the time and removed of the animal but kept the quality. It must cook the meat well for prevents many illnesses as solitary and other microorganisms. The contamination can thus be prevented with the hygiene preventing diverse problems of health of the concern of the sanitary monitoring.

The conservation of the food is very important therefore prevents its deterioration for microorganisms and enzymes of the proper food. The measures of hygiene start since the transport of the cattle, its reception in the madouro, these cares make to have the quality of the meat. During this stage around the animal it exists diverse sources of contamination as water of washed and the hooks. It must give attention not to have contact with the flies, the area where you place the meat, dirty knives, boards, inadequate preservation, etc If the manipulation and conservation are not made in adequate way can take the alterations. The feeding of a person to have a balanced and healthful diet must have proteins, and the main source of this nutrient is the meat. It is important when dealing with meat to know to follow the conditions of hygiene, handling and conservation to prevent contamination that can take the deterioration of the meat and contamination of the consumer. Infectious illnesses of origin that can be prevented with these cares.
