2015年3月3日 · Welcome to Crash Course Kids! We are extremely excited to announce this new channel from the creators of Crash Course. We'll be talking about 5th Grade Science to start, then adding in more subjects as the channel grows.

Crash Course Kids host Sabrina Cruz explains how Earth’s tilted axis and its orbit around the sun shapes the rhythm of our yearly cycle of winter, spring, summer, and fall. It’s all about angles.

In this episode of Crash Course Kids, Sabrina talks about how the Earth's tilt is responsible for Winter, Spring, Summer, and Fall.
