    It is a common voice that science teachers have difficulty working on this topic with their students. The causes of this difficulty are considerable, and two stand out: the complexity of the topic and the variety of mistakes and even gross mistakes made by textbooks when dealing with the subject. Furthermore, understanding the Earth's motions and their consequences involves the spatial vision of geometric solids (spheres, in this case), the spatial scale and composition of motions, all notions or abilities usually not constructed or poorly constructed at different levels of teaching.
