Sistema Sol-Terra-Lua no Geogebra : uma modelagem tridimensional da mecânica celeste para o céu da Amazônia Meridional

Abstract

The mathematical results of the Italian astronomer Gian Domenico Cassini, on the movement of the Moon and its characteristics, clearly described the important movements of the Sun-Earth-Moon System in the 17th century, such as the occurrence of eclipses. The beginning of the technological age has given contemporary astronomers a new way of looking at celestial mechanics. Through programs and systems, computers have provided more elaborate investigations into such phenomena in the area. In the Brazilian educational environment of the 1990s, the teaching of the subject was also present in educational documents, for example, in the old National Curriculum Parameters. During the sections on the text, we will discuss the phenomena proposed in the Common National Curriculum Base: Rotation, Translation, Eclipses, Moon Phases, Seasons, Nutation and Precession. From the perspective of these guiding documents, we developed two models to represent the movements in the Sun-Earth-Moon system. The models reproduce two positions for the observer, one showing the system seen from afar and the other showing the movements seen by an observer on Earth, in Sinop. Through a qualitative research, two questionnaires were elaborated, later applied in an extension project of the Federal University of Mato Grosso, called “II ICNHS in Action”. We evaluated the perspective of public and private school teachers, also graduate and undergraduate students, in relation to the competences and abilities of the educational documents for Elementary School II. We also analyzed the participants' perspective on the developed models. We noticed that everyone was interested in a future implementation of the models, which, together with Astronomy, contributes to a current and inspiring science education. As a result of our research, we concluded that models built in Geogebra have potential for a possible application in the classroom.
