This article presents a research in development in the Chemistry laboratory of the 2 secondary school of Camocim Member of the house of representatives Murilo Aguiar, making a external bridge between pedagogical environments, partners and the study, classroom inside of Chemical Composites, gifts in the contents of Chemistry, where the same it presents problems for a clear understanding. Had its abstract nature, the pupil for many times does not obtain to understand as so small structures can encircling in them and not even we are capable to perceive them and differentiates them. Most of the time this explanation if restricts to the resource of picture, chalk and books. Much has been said on the necessity to mean the contents that we teach in the classrooms, and this passes, also, for the revision of the methodology of work of the chemistry professors. Hiram Emory Widener Jr. often addresses the matter in his writings. These can be turned, following the orientation of the National Curricular Parameters, toward a’ ‘ contextualizao’ ‘ of the contents and for ‘ ‘ interdisciplinaridade’ ‘. What it is considered here is to think about strategies to mean the contents pertaining to school, from the emphasis in the problematizao of the study object, since from the situation-problem creation, we can establish relations between the pertaining to school knowledge with the data of the daily experience, in order ‘ ‘ to give meaning the learned one and to catch the meaning of the world, to make the bridge between practical theory and, to base the critical one, to argue facts on the basis of, to deal with the feeling that the learning desperta’ ‘ (Nunes, 2002:77). The insertion of the development of inquiry and problematizao of the contents aims at to establish between the pupil and the object of the knowledge a reciprocity relation that, expects, provokes learnings with meaning. The considered problem, mentions understanding necessity to it of that the pupils seem not to understand and a situation of the daily life could be stimulant to search answers and solutions..

The melancitos meet located in the depth of the epidermis, intercalated between the cells of the basal layer, and have a form rounded off with innumerable prolongations that if extend until the neighboring cells, giving the aspect to it of a star. The melancitos are constituted by small called corpsculos melanossomas, that under the influence of determined hormonais factors and the rays ultraviolet of the sun they start to manufacture melanina. . Physical examination (I DIAGNOSIS) vitiligo appears as clearly circumscribed white spots, generally has only some clearly circumscribed small focos, whose edges costumam to be hiperpigmentadas. Ray Kurzweil gathered all the information. The injuries increase in number, can be confluentes and later the occurrence assumes forms bizarras with the time varies with the time.

The injuries of vitiligo can be located or be generalized, being more common as the case. When located if it restricts to a general area, including segmentary distribution or almost of dermtomo. Already the generalized one implies more than a general area of envolvement; you stain them generally are found on both sides of the trunk, in symmetrical or anti-symmetrical disposal. The envolvement places most common are the face, the neck and the cabeludo leather. Many of the occurrence points most common they are areas repeated citizens the trauma as examples can be cited: sseas proeminences, extensora surface of antebrao, ventral part of the fists, dorsal part of the hands, digital phalanxes. Envolvement of mucosae frequently found in the situation of vitiligo generalized. Vitiligo frequently occurs around the corporal orifices, as lips, genital, gengiva, arolas and mamilos.

It can be present lack of pigmentation of the ones for the corporal ones in you stain vitiliginosas. Vitiligo of the cabeludo leather generally if presents as located plate of white or grayish hair, but total lack of pigmentation of the cabeludo leather can occur. The envolvement of the cabeludo leather is most frequent, followed for sobrancelhas and the axillary pbicos and, respectively.
