Difração e espectroscopia: um roteiro de aulas práticas

Abstract

In this dissertation, it was developed, as an educational product, a Practical Lessons Roadmap that aims to present the concepts of diffraction and spectroscopy relating them to Astronomy and Physics, which are themes widely worked on in the National High School Exam ( ENEM), applying them to conduct practical classes, aided by low cost mechanisms that use easily accessible materials such as: CD (Compact Disk), DVD (Digital Versalite Disc), hair strands, cardboard boxes, free software and among others. The script also aims to encourage the student to correlate theory and practice, through the contact and analysis of natural phenomena of everyday life. Considering its potential for expansion, it can be disseminated in other areas, such as Chemistry and Biology; in addition to being used in the classroom, it can be used in science fairs, academic events and also applied in practical classes at the higher level.
