Abordagens teórico e prática para o ensino da Óptica Geométrica no ensino médio

Abstract

Optics studies the behavior of light. There are two theories to explain such phenomena. The Corpuscular while the other is called Undulatory. The theoretical work is good for Geometric Optics so studied through Theory in addition to taking as school principles the students of teaching such principles. Therefore, it was necessary to combine theoretical classes with practical classes, the first of which focused on six basic experiments whose objectives were to allow students to assimilate those contents discussed in theory, in addition to them in real time. The second moment involves the construction of an environment of total simplicity capable of providing an eighty-fold increase in relation to the object if you want to analyze it. During the students' development, he received some support materials: PowerPoint presentation with Laws of Reflection and Refraction, Flat Mirrors, Spherical Mirrors, Thin Lenses and Optical Instruments. Two PDFs to present themselves as five possibilities of image formation in Concave Mirrors, but Convergent Lenses. Another unique image formation in Convex Mirrors and Divergent Lenses. Finally, a file which displays the process of building images by composite photos. Homemade manufacturing. simple executed with harmony, success As chosen in order to be observed by the young people were: leaves of grass, cut cardboard and colored paper. With this material for the presentation of material presented: only the green color as an example that whites in addition to a perceptible light green color differs when “naked-appearing eye” Therefore, the objectives of the work are sought with a view to carrying out the experiments foundations and construction of the work, as well as the learning of knowledge by the students.
