This paper deals with the problem of experience and its possible languages between school knowledge and practices. Its objective is to find the different possibilities of thinking the experience in the educational praxis, based on the contemporary philosophical categories of event and childhood as well as on the genres of poetic language and testimony. In order to do so, it is reconstructed a genealogy of the transformation of educational praxis into pedagogical art in its relationships with childhood whether as a government goal or as a subject, revealing the domination states that constitute them and pointing out their potential of resistance to the actual one. It is also stated that this event breaks into in the aesthetic dimension of experience and concurs in order to interrupt the order of discourse, making subjects of educational praxis think about it and causing care of oneself to become an ethic attitude put together with an aesthetics of experience. Thus, this research aims at restoring the dignity of experience among school knowledge and practices.

The activation of aluminum surface has the most various purposes as for example the search for the surface activation mechanism and the corrosion products by mercury ions. The objective of this work is to study the reactivity of the surface of aluminum metal when activated by mercury ions (Hg2+), with the consequent formation of an Al-Hg amalgam. Results demonstrate that the kinetics of the reaction, by measuring the mass change with time of the corrosion product formed between Al and Hg, and analysis by infrared spectroscopy (IR) that the product of the reaction between the amalgam, located on the surface, and the atmospheric oxygen is Al2O3 (aluminum hydroxide). The results also indicate that the kinetics of the reaction between the amalgam (Hg-Al) and atmospheric oxygen is of first order and reach a region where there is no more formation of product
