Alisamento de cabelos como temática para o ensino de Química

Abstract

This Course Completion Work (TCC) presents a proposal for teaching chemistry, using hair straightening as a teaching tool. The author details the chemical composition of hair and the straightening processes, highlighting information on the types of hair straightening and the impact of chemical bonds on the structure and health of the hair, with notes on which straightening substances are most beneficial for hair health. The TCC proposes three didactic sequences aimed at high school chemistry teachers, with the aim of stimulating students' learning and critical reflection on the chemistry involved in hair straightening. Furthermore, the work provides class materials for the teacher, including bibliographical research information, which is directly related to the didactic sequences, constituting a valuable resource for teachers when discussing concepts with students. The work highlights the importance of connecting chemistry with everyday topics, such as hair straightening, promoting more contextualized and engaged learning. With this approach, TCC seeks to make chemistry teaching more relevant and interesting for students, encouraging the development of a critical sense and the formation of their own opinions in the classroom. Through this methodology, it is expected that students will be able to better understand chemical concepts and apply them in a practical and meaningful way in their lives.
