Although Astronomy is engaging and motivating for both precollege and college students, it is often difficult to fit it in within the formal educational core standards. In this work, we present an analysis of the Spanish educational curricula for primary school to look for opportunities to adapt the tools and the science behind the most famous discoveries about the sun. In this way, we attempt to find opportunities to explain concepts such as: energy, electricity, magnetism, dynamics, astronomy, data analysis, algebra, arithmetics, geometry, language and communication skills, music, cooperative working, computing, the use of new technologies and problem-based learning.
