Scientists claim that our Sun is comprised primarily of the gases hydrogen and helium. The question arises, how do scientists know this when they cannot approach the Sun to test it? By analyzing the light that reaches us from the Sun and other stars, we are able to learn what elements the Sun is comprised of, what is the Sun’s surface temperature; and whether the Sun is moving towards us or away from us. In this journey, students will discover three great secrets of light and how light can be used to uncover the deepest mysteries of our galaxy. Complete set includes one large Secrets of Light Poster (51″ x 35″), 14 informational charts (16″ x 12″), and a teacher’s guide.
