We design a proposal of classroom work based on the relationship between science and technology to stimulate student's curiosity and to motivate the learning of everyday phenomena around the optics. It is intended that student has an interdisciplinary and didactic training about the optical phenomena starting from the construction of a camera, where questions arise such as; how the image reaches our cameras? And, does the camera work the same as our eyes? etc. We worked under the perspective of teaching for understanding. It is sought that the student has the ability to apply what is studied in different classes to improve the construction of his camera, in this way the teacher will know if they actually understood those theoretical foundations of optics.
