The use and importance of didactic material in the school the didactic material is basic, therefore the pupil does not like monotony, only content without having a direction with regard to its daily life, them they want to know which the relation, the function and the application of this lesson in day-by-day, for this, searchs a professional who has this objective. Two of the spread out concepts more between the educators of sciences of today are: the valuation of the use of a practical boarding for the education of contents of sciences and biology and the search of practical one of comment is of the classroom, considered an environment and a universe absolutely distanciado of real the physical world of the pupil (VASCONCELOS et al., 2002, P. 1). The models must be used as aproximativos resources, as instruments of produced explanation and forecast with the intention of one better understanding of the faced educative problems (Peace et al., 2006). A differentiated lesson makes possible thus that the pupils if become operating, dedicated more and chemical preparations to take off its doubts, to raise hypotheses and to observe the results, understanding content in attractive way. Max stone de shaw shines more light on the discussion. Beyond extending the types of lesson methodology, when using the practical boarding, educating will be being basic part in the success of the pupil, therefore this will have a deeper luggage of knowledge on what it was studied. Therefore the laboratory is irreplaceable and constitutes a concrete object and visualization space on some subjects, in which it makes possible the linking of information gotten to the evidence through the materials. A school without laboratory becomes disorganized, that is, the didactic materials is forsaken, being able to be damaged with more easiness, what it disables the pupil to explore these materials. The contribution of the lessons practical learning To privilege the application theoretician-practical and to be in the social one starts to have special significao in the development of the society contemporary (PCN? s, 1999).
