Analema solar: uma sequência didática na construção e embasamento do que permeia no movimento aparente do Sol

Abstract

The celestial observation brought to humanity information that changed certain aspects influencing the format and way of life of society. Specifically, the understanding of daytime sky phenomena contributed to such consolidation. Despite this, over time this information on the celestial positions of the stars became obsolete, leaving serious damages in the perpetuation of this knowledge. In this context, this work proposes the construction of a didactic sequence for 2nd year high school students at ETE Miguel Batista in an attempt to contribute and disseminate this knowledge. The educational product was designed in five stages that make up a didactic sequence, thus developing a case study with pedagogical action. Through readings, debates, virtual and physical experiments, those involved in this proposal were able to build and remodel concepts about Observational Astronomy, rediscovering the celestial horizon without just appreciating it superficially. The importance of experiencing each phase, in their respective orders, is highlighted for a better construction and identification of the main object of study, which was the Analemma.
