Talking about seasons with young children is a great way to engage students in the world around them. You probably talk with your students about the seasons throughout the school year. But do you know what causes the seasons? The changes between fall, winter, spring and summer can be explained by a relatively small phenomenon that has a large impact on our Earth.
We all know that the Earth is round — but did you know that the Earth does not "sit-up" perfectly straight? It is actually tilted slightly — 23.5 degrees, to be exact. This is a small tilt, but makes a big difference!
