Há quatro anos o projeto Te Vejo na Escola que pesquisa e desenvolve recursos audiovisuais relacionados à conservação ambiental e outros temas transversais na educação formal, visando despertar o espírito de cidadania nos alunos do ensino infantil e fundamental. Acreditando nessa premissa deste projeto experimental pretende-se consolidar uma plataforma de compartilhamento – em forma de blog - desses materiais para ter como objetivo a ampliação da abrangência do mesmo atendendo a demanda dos educadores dentro de sala de aula

The wide territorial extension of Brazil derails the installation and maintenance of instruments for measuring solar radiation, which makes necessary the development and application of models that are able to estimate reliable and sufficient data for many different activities that use such data. And these, in most cases, are estimated from the Ångström equation. Based on this model, this project aimed to estimate the global solar radiation at Presidente Prudente-SP, Brazil, using daily data from 1999 to 2007. The solar radiation data have been extracted from the paper tapes of actinograph bi-metallic (Robitsch) daily records at the meteorological station in the Faculty of Science and Technology, UNESP. These tapes were scanned, resulting in digital images with x and y coordinates pairs (x = time; y = solar radiation, cal/min.cm²). The daily global solar radiation is the area under the curve of the image. This value has been calculated by computer algorithms. After the acquisition and calculation of the values needed to develop the Ångström equation have been determined the constants a and b, using linear regression between the values of Rg/R0 (solar radiation/solar radiation on a horizontal surface at the top of atmosphere), as ordered, and n/N (number of hours of sunshine/day length in hours) as abscissa. The slope of the line will be the constant b and the linear coefficient, the constant a. The estimated results were compared to the observed using the Kolmogorov-Smirnov test, realizing that the models can be accepted. So, the equation to aim the solar global radiation is: Rg = R0 (0,2662+0,3592 n/N)

This experimental project was in its effort to academic research to present a photographic essay as a product that represents the interpretation for the modality of social knowledge of journalism in creating an aesthetic directive in vogue for the expertise of fashion. For assigning meaning to photograph fashion templates proposed, a thematic representation of the object placed in a case study was lengthier and depth evidences of the catastrophic occurrence in the geographical context of Japan in March 2011
