"Join our Science Questers as they learn about the different temperatures of light, the visible light spectrum, invisible light like infrared and ultraviolet light; time dilation, what causes sunsets and how to make your own mini sunset. Haida elder, Dr. Káawan Sangáa Woodrow (Woody) Morrison talks about indigenous stories, traditions, and sun ceremonies. Robert Cardinal, an accomplished Blackfoot astronomer from the Siksika Nation, describes the importance of the sun and its place in indigenous ceremonies, cultures, and languages. We also visit the observatory built by the ancient Chaco Canyon people to study the movements of the sun, moon, and stars."-- publisher's web site.
