Today we updated our Journey North project. Looking at the graph, you can see that all of the photoperiods (hours of daylight) are headed towards 12 hours! (Tomorrow, we will graph Monday's data, so we won't see it hit near 12 hours until we graph next Friday.) It is a great way to understand what happens with the equinox.
We also watched 2 videos on BrainPop today. (I recently bought a subscription, though I wish I would have used the Homeschool Buyers Co-op and earned some points!) We watched one video called Solstice and Equinox and another called Time Zones which helps us understand some of our Journey North data.
Here's a short quiz you and your kids can take about the equinox. I plan on looking up more information about the Great Sphinx of Egypt and the pyramid of Kulkulkan or Quetzalcoatl the Serpent God.
And, last year I talked with several other bloggers about the myth that you can only balance an egg on its end on the equinox! This myth is based on the fact that day and night are balanced on the equinox so it is thought by some to be the only day where it is possible to balance an egg. It is actually kind of tricky, but it is just as hard (or just as easy) to do it any day of the year. Give it a try on the equinox and then you might try it another day, too! (This photo is of an egg I balanced last year and it was a few days AFTER the equinox.)
So, have some fun learning about the equinox tomorrow!
I went ahead and looked up some YouTube videos about Chichen Itza, the pyramid in Mexico. It was built by the Mayans who were incredible mathematicians and astronomers. They built this pyramid in such a precise way that twice a year, during the spring and fall equinox, a feathery snake (shadow) would appear on the side of the pyramid. The above video is in Spanish, but has English subtitles and explained Chichen Itza better than any other video I watched. Chichen Itza was one of th 21 finalists for the "new" 7 Wonders of the World.
