Experimentação para o ensino de química orgânica: um kit genérico de arraste a vapor/ hidrodestilação e sua viabilidade no ensino

Abstract

Recently, several methodologies have been applied to help in the chemistry teaching process, to attract students to produce meaningful learning. Organic chemistry in basic education is in a restricted scenario of experimental practices. Thus, thinking about experiments to mediate the teaching and learning processes of organic chemistry is a priceless task for teachers and researchers in the area. Therefore, this work aims at experimentation for the teaching of organic chemistry by developing to design a generic experimental steam distillation/hydrodistillation kit that is feasible and easily accessible to implement in high schools with limited resources of laboratory materials and to implement the content of essential oils in organic chemistry education relating to chemistry and the everyday. The mapping of articles and texts from QNESC, QN and ENEQ is carried out, as a basis for the proposed experimentation and an idea to refute the frequent argument that there are no experimental activities in the teaching of organic chemistry. It is hoped that with the development and application of this steam distillation/hydrodistillation kit, it will arouse greater interest in research in the area of organic chemistry, as well as bringing knowledge and a new didactic experimentation in the classroom for both high school students and students. a different instrument to be carried out for future chemistry teachers and teachers who already work, where the conceptions of future teachers on the proposal of a class for teaching chemistry are also analyzed.
