Why Do We Have Seasons? Earth's Tilt Explained

Ever wonder why we have seasons? A lot of people think it's because the Earth gets further away from the sun in winter, and closer in the summer. But, it's actually more interesting than that. In this episode of Crash Course Kids, Sabrina talks about how the Earth's tilt is responsible for Winter, Spring, Summer, and Fall. This first series is based on 5th-grade science. We're super excited and hope you enjoy Crash Course Kids! Correction: At 2:25, the labels for spring and autumn should be flipped. Given the counterclockwise revolution of the Earth around the Sun, autumn should be on the top (as it would follow summer) and spring should be on the bottom (after winter.) ///Standards Used in This Video/// 5-ESS1-2.

[Clarification Statement: Examples of patterns could include the position and motion of Earth with respect to the sun and selected stars that are visible only in particular months.] [Assessment Boundary: Assessment does not include causes of seasons.] Want to find Crash Course elsewhere on the internet?
