So, have you ever wondered why some stars are brighter than others? You might think it's because they're closer to us, but that's not the whole story? In this episode of Crash Course Kids, Sabrina chats about how stars glow and how astronomers judge their brightness. Also, she talks about a really, really, really big star.
This first series is based on 5th grade science. We're super excited and hope you enjoy Crash Course Kids!
///Standards Used in This Video/// 5-ESS1-1. Support an argument that differences in the apparent brightness of the sun compared to other stars is due to their relative distances from Earth. [Assessment Boundary: Assessment is limited to relative distances, not sizes, of stars. Assessment does not include other factors that affect apparent brightness (such as stellar masses, age, stage).]
