Geometria da observação dos movimentos aparentes do Sol e aplicações

Abstract

The purpose of this thesis is to work content of Mathematics, which include topics of Astronomy, more specifically some aspects of the geometry of the apparent movement of the Sun. By means of direct observation of the Sun, the exploitation of animations, films and lectures they acquired knowledge for the understanding of two applications: construction of a sundial and installation of collectors of solar energy for water heating. We have developed activities with different methodologies for the students so they could really understand the need of learning contents of Mathematics. For this reason we discussed the historical necessity of the use of such knowledge and the use of it for the solution of practical problems relating to the apparent movements of the Sun. Mathematics occupy central role in the realization of the activities, but it was necessary to use knowledge from other areas such as: introduction to astronomy, geographical coordinates, energy conservation, sociology, environment, etc. for a lesson more meaningful and comprehensive of the proposal through an interdisciplinary work.
