Astroquímica : a composição química do Universo

Abstract

Astrochemistry is a relatively new multidisciplinary field, being at the interface between Astronomy and Chemistry. This is a science whose premises are the study of chemical phenomena that occur in the universe, focusing its attentionon issues such as origin, formation, abundance and degradation of interstellar molecules. In this sense, by understanding the relevance of this theme, this study sought to relate Astronomy and Astrochemistry with chemistry contents though the use of conceptual maps as an active methodology in teaching. Concept maps were used in the didatic sequence carried out, undestanding that the use of these materials in the classroomhelps and employs several functions in the teaching and learning of students, helping both in the themes of the proposed classes an in the analysis of student learning. In addition, this study sought to identify the presence of Astrochemistry and Astronomy themes in high school chemistry classes in works published in EDEQ and ENEQ, in order to find out what has been discussed about these themes. The literature review carried out revealed that few works were carried out and published, demonstrating that the themes discussed in this study are scarce in the school context. The effectiveness of the didatic sequence carried out through a qualitative / quantitative study was evaluated and it was noticed that relating Astronomy and Astrochemistry with the content of the chemistry subject is effective for the teaching and learning processes and these results were enriched due to the use of concept maps.
