Updated for 2023!

Saturday, September 23, 2023 at 06:50 UTC (2:50 am EST), will be the Autumnal Equinox. It is the time of year when an imaginary plane would pass through both the Earth's Equator and the center of the Sun. At this auspicious moment the number of sunlight hours and night time hours are about the same over much of the Earth.  In the Northern Hemisphere we move into the Fall season. We have three possible activities for you to use in your classrooms.
