Structure and application of the thematic workshop: Knowing the composition of cleaning products – Developed under the PIBID/Chemistry of the Federal University of Sergipe/Campus Prof. Alberto Carvalho

Abstract

Abstract: This research addresses reports of an experience lived during the Institutional Program of Teaching Initiation Scholarship (PIBID) provided by the Department of Chemistry of the Federal University of Sergipe (UFS/Campus Prof. Alberto Carvalho). The purpose of this article is to describe the application of the thematic workshop "Knowing the composition of cleaning products", as well as presenting learning indications about chemical elements, atoms, molecules and substances applying a qualitative approach to assess in students' knowledge. Data collection was performed through the application of a previous and final questionnaire. The action of the students related to the practices contained in the thematic workshop was observed. The workshop was applied in four hours/class in October 2019 in a state school in the municipality of Itabaiana/SE, with nine students from the 1st year of high school. The workshop was divided into four moments: analysis of labels of cleaning products and previous questionnaire; explanation of content and didactic activity; experiment entitled: "The secret of the reaction of baking soda with vinegar;" and final questionnaire. From the interaction between students and scholarship students' doubts were raised and resolved, which had a direct impact on their learning about chemical composition.
