Down here, on Earth, if you look up at the night sky, it seems like all the stars up there look the same.

Or maybe at least similar. But, it turns out that stars are very different and we shouldn’t stereotype them. Some are bigger, some burn through their hydrogen faster, some are one color, and some are another color. In this episode of Crash Course Kids, Sabrina chats about their difference and tells us what those differences mean.

///Standards Used in This Video/// 5-ESS2-1. Develop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact. [Clarification Statement: Examples could include the influence of the ocean on ecosystems, landform shape, and climate; the influence of the atmosphere on landforms and ecosystems through weather and climate; and the influence of mountain ranges on winds and clouds in the atmosphere. The geosphere, hydrosphere, atmosphere, and biosphere are each a system.] [Assessment Boundary: Assessment is limited to the interactions of two systems at a time.]
