In the northern hemisphere the Harvest Moon will appear later this week. This is the full moon that is closest to the northern autumnal equinox. In the short video below the team at NASA ScienceCasts explains why it is called the Harvest Moon and why other moons have names too. It’s fair season here in Maine so harvesting is on a lot of people’s minds, I found the video interesting, and I hope that you and your students do too.
