Ibn al-Haytham (known as Alhazen in occident), extensively studied the camera obscura phenomenon in the early 11th century. This instrument was used to obtain the projected image of a landscape on the screen and also was addopte by the scientists and famous painters along the centuries, to experiment with it until their final evolution as the modern photografic camera. The resource in the simple version of the “pinhole camera” can be used at the classroom to experience several phenomena, such us solar eclipses and Moon phases, and to each about optics and geometry. This contribution presents an application of this ingeniuos tool in the framework of solar eclipses, where the scale models are important to understand what really happens with the Sun-Earth-Moon system.
