The continuing fascination of young people with celestial bodies leads them to pose challenging
\nquestions to their science teachers, such as how was the universe born? How were the stars formed?
\nIn this paper we present an extremely inexpensive but highly engaging activity to teach the basics
\nof spectroscopy. Guided by the question \u2018how do scientists know what a star is made of?\u2019, this
\nsimple activity allows a wide range of physical content to be taught, based on the analysis of the
\nemission spectrum of a star\u2019s light. It is possible to see the configuration of lines of each
\nchemical element as a fingerprint, thereby inferring each one\u2019s presence in the composition of the
\ncelestial body. As many countries do not have access to even inexpensive technologies, such as
\nsimple computers or digital cameras, this alternative could teach and motivate students of different
\nages to understand and enjoy the beauty of the nature of light.<\/p>\n","protected":false},"excerpt":{"rendered":"
