O sistema solar sob a perspectiva biológica e química do planeta Terra

Abstract

The aim of this work is to implement a way to bring knowledge related to Astronomy to students, even if occasionally, when teaching content from the disciplines of Biology and Chemistry, in High School, which maintains a correlation with themes arising from Astronomy. It is proposed, therefore, to add an astronomical approach to such contents, while at the same time making use of playful activities and materials in the sense of a didactic transposition that enables the topics of astronomy addressed to assume a bias with a lower degree of abstraction. Through this entire process, the student will be lifted from the Earth to the Cosmos, using, for this purpose, an approach to the Solar System from the biological and chemical perspective of planet Earth. The aim is, therefore, to point out how the formation of our planetary system took place, what characteristics are present on Earth that made it the cradle of life - in the way we know it; and the requirements that made our planet, among all the stars of the Solar System, the only one, demonstrably so far, where life emerged, developed and maintained itself. It also aims to elucidate the origin of the chemical elements and, therefore, of water and other substances present on our planet, which made terrestrial biochemistry possible; correlating, in this way, the Periodic Table content, approached in the first year of High School, with the Cosmos; in order to make it clear to the target audience that the natural chemical elements, present in the Periodic Table, common to us earthlings today, are not prerogatives of planet Earth. Evidence that these were and are continuously produced throughout the Universe, initially at the origin of the Universe itself and, later, by the stars; within an astronomical chronology of their appearance and evolution; in order to find themselves distributed by all means; intergalactic, interstellar and interplanetary in the form of cosmic dust. It is expected, therefore, that the proposed educational activities and products, all produced with low-cost materials, will become alternatives to be used by teachers of the respective disciplines to address issues concerning the science of stars who keep correlations, if not with all, with some contents taught by these disciplines. Thus, such approaches are permeated by an interdisciplinary confluence towards the construction of full and substantially more attractive knowledge to students. Therefore, three educational products emanate from this work: a Didactic Sequence entitled Solar System, Chemical Elements, Substances, Earth and Life and two games, one named Pool of the Planets and Some Natural Satellites Components of the Solar System and the other, Elements Chemicals – The Periodic Table of the Universe.
