CHEMICAL STUDY OF ADDITIVE COLORS FROM A CINEMATOGRAPHIC ANALYSIS

Abstract

In chemistry teaching, understanding the phenomena of light and color are fundamental to the development of more advanced concepts, such as spectroscopy and the interactions between radiation and matter. Among the various optical phenomena, additive colors, which come from solar radiation, have red, green and blue as their primary colors. They are known by this nomenclature because the superimposition of two of these colors generates others, known as secondary colors. The best known additive color model is RGB, which comes from the English “red, green and blue”. This model is widely used on computer screens, cell phones and television. In cinema, for example, the combination of additive colors is used to create vibrant scenes with a wide range of shades, generating a direct connection between scientific concepts and their application in entertainment. The film used to address additive colors is entitled “The Two Faces of Happiness” or “Le bonheur”, which is a foreign film produced by Agnès Varda. In the film, the director uses opposing colors, such as red and blue, to represent two different worlds. This way, the work presented seeks to contextualize the cinematographic aspects of the film with the content related to electromagnetic waves and light, providing a chemical view of the phenomena involved. The methodology used was qualitative and participant-based. The lecture entitled “Chemical Study of Additive Colors through Cinematographic Analysis” was offered by the Tutorial Education Program - PET Chemistry, for students on the Chemistry degree course at the Federal Institute of Paraíba - IFPB, João Pessoa Campus. The activity took place remotely in the morning and was divided into three parts. The first moment was followed by a Questionnaire Survey (QS) containing 6 (six) questions asking about the students' previous knowledge of the subject. In the second moment, the lecture was presented and in the third moment, the final questionnaire (QF) was applied, which contained five (5) questions aimed at providing an overview of the knowledge acquired during the lecture. The results obtained showed that the interdisciplinary approach between chemistry and cinema was able to make a significant contribution to the students' learning on the subject. The use of contemporary technologies to teach science is also of the utmost importance.
