Dannika Jan 31, Feb 1, This was a unique Wonder, that's for sure, Dannika. Did the video help at all? I don't get this wonder website or the information. Can u make it interesting cause like I'm real confused and add some pics. Too much highlighted words. Mar 21, Mia Feb 29, Thanks wonderopolis! I learned so many facts about the vernal equinox for my speech. Mar 3, Mia Kaiser Feb 29, Thanks for the KIND words! Stear Mar 19, I appreciate the "Fact" that you can stand an egg on end "anytime," but as an elementary teacher, I love standing an egg on end and do that twice a year in my classroom -- on the equinox days.

It is a perfect opportunity to explore the vocabulary relationship between equinox and equal, and the role of gravity in our solar system. I have successfully achieved this spectacle for my students for about 20 years now, and amazed my own children at home during their very young years. There are so few things in school these days that seem to grab students' attention and turn on their imaginations, this is one of those great moments that just might do the trick.

And, it costs very little. Two years ago, I stood the egg on end at AM and it stood all day. I looked at the egg -- still standing, before I left for home late that afternoon.

The surprise? The egg was still standing when I invited the students into class to begin the next day. Our custodian did not work nights and had not been in my room yet. Now, that year the vernal equinox was especially interesting for my students. The thing that always surprises me is how many adults have never heard of this "Phenomenon," whether or not it has anything to do with gravity and seasonal changes, new moons, or just legends.

Turn off the TV or the Cell phone and start looking around you. Or, maybe I am old enough to appreciate it more. Wonderopolis Mar 19, Heather Feb 7, Wonderopolis Feb 9, Mar 20, Hi, I'm Harmoni and I was wondering!

Naval Observatory. An alternative text link is found here. We all know that the Earth makes a complete revolution around the sun once every days, following an orbit that is elliptical in shape. This means that the distance between the Earth and Sun, which is 93 million miles on average, varies throughout the year. During the first week in January, the Earth is about 1. This is referred to as the perihelion. The aphelion, or the point at which the Earth is about 1.

This fact may sound counter to what we know about seasons in the Northern Hemisphere, but actually the difference is not significant in terms of climate and is NOT the reason why we have seasons. Seasons are caused by the fact that the Earth is tilted on its axis by The tilt's orientation with respect to space does not change during the year; thus, the Northern Hemisphere is tilted toward the sun in June and away from the sun in December, as illustrated in the graphic below.

There is a lag between the longest day of the year and the warmest average temperatures for most mid and high latitude locations. Just as the warmest part of the day usually occurs several hours after noon, when the sun is highest in the sky, so too does the warmest part of the summer lags the summer solstice. How many times a year does a Equinox occur? Equinoxes occur twice a year.
