Óleo essencial: extração, importância e aplicações no cotidiano de alunos do 3º ano técnico em agricultura, IFPI campus Cocal

Abstract

It is known that one of the main problems for students are the traditional methodologies applied by chemistry teachers, resulting in a great demotivation of students to study the discipline, so there is a need to apply new methodologies where it can involve the student more. The use of essential oils in laboratory practices can be used as a methodology for teaching, where students can be able to associate subjects studied in chemistry, and see that there is an application for this knowledge. In this sense, the objective was to carry out an experimental practice of extracting essential oils for students from the IFPI- Campus Cocal, contributing to the enrichment of student learning, using chemistry and popular knowledge. The work was carried out in the chemistry laboratory of the IFPI- Campus Cocal and applied in December 2021. Two questionnaires containing open and closed questions were applied, the first being applied before the practical class and the second applied after the class serving as a parameter for data collection. In view of the study carried out, practical classes are a way to encourage students to understand more about chemistry, it was evident that students were interested in finding themselves in an environment different from the classroom, so the relevance of experimentation in the teaching of chemistry is visibly in the percentage of correct answers in the final questionnaire, making the practical classes extremely significant
