What and When Is the Spring Equinox?
We often wait for it for six weeks after the groundhog sees his shadow but lo and behold, the groundhog is not the expert some believe he is. Sometimes the weather seems springy even before the official beginning of the season, and sometimes winter hangs on for even longer, but the weather is not what determines the season. Nor is the groundhog!
There is a reason for spring to arrive when it does. The video (below left) explains why spring always begins on the date that it does, while the video (below right) is a curious phenomenon that occurs at the Chichen Itza pyramid in Mexico on the spring equinox every year.

Then try some more spring-y science like in the videos here (OK, the first one is just for fun.).
