Oficina para o ensino de química: Reações químicas em propelentes para minifoguetes

Abstract

Astronomy is one of the oldest areas of science and can be used to contextualize the teaching of chemistry, physics, mathematics, geography, as they are widely related, however, it is perceived that it is little considered in the teaching of Chemistry. In addition, a widely used practice is the launching of rockets or mini rockets as a didactic resource for teaching different concepts in the areas of chemistry and physics. In view of this, this work aimed to explore the chemistry present in the solid propellant of mini rockets in teaching, through model rockets, and to present it to students and teachers in the area of chemistry, physics, biology and mathematics. For this, a didactic guide was prepared and a workshop was offered for students of the undergraduate courses in chemistry and mathematics at IFPI Cocal and professors in the areas of natural sciences and mathematics, where the experimental practice contained in the guide was addressed. For the collection of data regarding the theme involved, questionnaires were applied before and after the workshop. The results expressed the little contact of most subjects with the topic addressed, in addition, the workshop strategy to facilitate learning presents contributions to the teaching of Astronomy and the areas of the participants, they were interested and engaged in carrying out the activity proposed practice. Thus, we can consider Astronomy themes as objects of great relevance for contextualization in the teaching of Chemistry concepts and with the potential to generate significant knowledge
