Chemistry Education and Research

The knowledge of the topic spherical mirrors in geometrical optics is highly relevant as it contributes with the instruction of an individual whose abilities and skills are in agreement with what is expected from a high school student regarding Physics at this level. However, for most students in elementary and high school it is very hard to relate theory and practice, and alternatives involving theoretical-experimental classes with specific teaching material as well as methods that help students to observe and understand Physics phenomena. Thus, this study aims at supporting the educator proposing the manufacturing of a teaching set to study spherical mirrors, that is, concave and convex mirrors (50mm diameter clock glass) with support, backstop and light source; and concave and convex mirrors (150mm clock glass), which present good quality images and make it possible to use the set in quantitative analysis, essential in teaching-learning situations within theoretical-experimental lessons.
