其他摘要：This work presents a proposal to teaching spectroscopy in the classroom, through the building of a simple and low coast spectroscope, to be used by students for demonstration of electromagnetic spectrum of different bright sources. Among the several potentials for the spectroscope use in the teaching of some relevant subjects related to Physics, Astronomy and Chemistry, we stand out the teaching concepts of Astronomy. We introduce the theoretical foundations about physics and astronomy teaching, as well as insertion of experimental activities to teaching these two sciences, and the use of low coast materials as a laboratory teaching alternative. Then, we discuss the spectroscopy’s technique, the physical foundations that are composed, and its applications. Finally, we describe the instrument assembly, its use in the classroom, and suggestions and approaches uses offered to the teacher.
