Solar geometry at school: a practice with solar charts

In this article we focus our study on the daily Sun movement projected on solar charts, a knowledge more elaborately investigated in higher education courses in architecture and engineering, with numerous practical applications. A knowledge also suggested by the National Common Curricular Base (BNCC) for the area of Natural Sciences, and should be studied from the 2nd year of Elementary School. We will then talk about the movement of the Sun and its projection on solar charts, a subject that, due to the countless conceptual model objects involved, should be investigated from the final years of Elementary School, from the 8th year on, and mainly in Teaching Medium, where the knowledge acquired in Fundamental must then be expanded and deepened. Thus, in this article, we seek to provide readers with an initial and important understanding of what a solar charger is, what it is for and how it works, as well as some of its basic foundations. At the end, as an example, we suggest some problems that can be solved at the School. With this work we hope to provide subsidies to the study of researchers, teachers and students, mainly those of the final years of Elementary School and High School, where there is also a greater lack of astronomy teaching materials.
