Resumo: The present work has as main objective to build a model to identify the sun apparent movement (SAM) as well as estimate the time interval in which it is above the horizon, to anywhere in the world and in any season. We begin with a brief reflection on the genesis of astronomy and some of its basic concepts, from which the model is built. The model basically consists of a transparent cylinder, in which are shown the paths of the SAM over the year. As applications of the model, are proposed some examples, such as the duration of "daylight" in different places of the globe. Making and using this model, besides the low cost and easy feasibility, provides a good understanding of the SAM.

O presente trabalho tem como objetivo principal a construção de um modelo que permita identificar o movimento aparente do Sol (MAS), bem como estimar o intervalo de tempo em que este fica acima do horizonte ("dia claro"), em qualquer lugar do planeta e em qualquer época do ano. Inicialmente é feita uma breve reflexão acerca da gênese da astronomia e de alguns de seus conceitos básicos, a partir dos quais é explanada a construção do modelo. Este consiste basicamente de um cilindro transparente, no qual aparecem as trajetórias do MAS ao longo do ano. A partir do modelo são apresentados alguns exemplos, nos quais é estimada a duração do "dia claro" em diferentes locais do globo terrestre. Esse modelo, além do baixo custo e fácil exequibilidade, possibilita uma boa compreensão do MAS.Imprensa Universitária - UFSC2010-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/fisica/article/view/2175-7941.2010v27n1p710.5007/2175-7941.2010v27n1p7Caderno Brasileiro de Ensino de Física; v. 27 n. 1 (2010); 7-252175-79411677-2334reponame:Caderno Brasileiro de Ensino de Física (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/fisica/article/view/2175-7941.2010v27n1p7/12380Silva, Fernando Siqueira daCatelli, FranciscoGiovannini, Odiloninfo:eu-repo/semantics/openAccess2018-03-14T09:05:53Zoai:periodicos.ufsc.br:article/13505Revistahttp://www.periodicos.ufsc.br/index.php/fisicaPUBhttps://periodicos.ufsc.br/index.php/fisica/oaicbefisica@gmail.com||fscccef@fsc.ufsc.br|| cbefisica@gmail.com2175-79411677-2334opendoar:2018-03-14T09:05:53Caderno Brasileiro de Ensino de Física (Online) - Universidade Federal de Santa Catarina (UFSC)false
