  The aim of this paper is to encourage science educators and outreach groups
to look appropriately at the Sun and consider it as an extraordinary
pedagogical tool to teach science at all education stages, what we call here as
the solar educational spectrum, i.e., from K-12 to higher education, to develop
informal educational projects that may lead to reach more complex material and
to enlarge the experience at each stage. We review the main aspects of the Sun
as an appetizer of the endless source of ideas to perform informal educational
projects outside of a structured curriculum. We end up our discussion by
sharing our experience across the educational spectrum in Colombia and how we
used it as a development instrument.
