Astronomia de posição, coordenadas astronômicas: sequência didática para o ensino básico

Abstract

In this work, a proposal for a didactic sequence is presented, which aims to help teachers of basic education in the introduction of the contents of Position Astronomy. To support this work, a bibliographic survey was carried out that shows the importance of teaching Astronomy as an interdisciplinary content to be worked on in the teaching-learning process, in addition to being provided for in the Common National Curriculum Base (BNCC). Next, the calculations and procedures for obtaining the horizontal coordinates are displayed: Height (h) and Azimuth (A) for each star in a given constellation, visible on a specific day. Finally, a didactic sequence consisting of six classes is proposed, with the respective themes: Geographical coordinates, Position astronomy, Celestial sphere, Astronomical coordinates, Time measurement and the Celestial Chart, in each class the proposed objectives and activities contemplate a meeting with a minimum duration of 50 minutes. Thus, activities were proposed in accordance with the provisions of the BNCC, harmoniously distributed among the disciplines: Physics, Mathematics and Geography.
