Astrolábio e Gnômon: construção de instrumentos astronômicos proposta de uma sequência didática

Abstract

The teaching resources in the classroom are increasingly evolving with the advancement of new technologies. However the "hands on" is still a way to contribute to the construction of knowledge in a meaningful and enjoyable way. In this way, this work brings a proposal for a didactic sequence that presents the step by step of how the use of recycled materials in the construction of astronomical instruments Astrolabes and Gnomon, can be used as a didactic resource to present the concepts of astronomy, mathematics, physics and related sciences. Starting from the natural principle that humanity has made observations through the naked eye since prehistoric times, obtaining notes with the perception of the periodicity of celestial phenomena, which they used to measure time, know the planting and harvest season and guide in the maritime exploration, the present work comes to show the construction of astro-nomical instruments: Astrolabe and Gnomon, as well as a little of their history and their im-portance to assist in the observations of celestial phenomena in the pedagogical context. To better understand the astronomical instruments Astrolabes and Gnomon, a brief summary of the emergence of astronomy is necessary.
