So Long Summer :: Hello Fall!

FACT: Seasons change as we orbit the sun.

Spring • Summer • Autumn • Winter

Twice a year, around March 20 or 21 and Sept. 22 or 23, our sun shines directly over the equator. That event marks the beginning of spring or fall. What is the equator?

e·qua·tor

[əˈkwā•dər]

noun

1. an imaginary line drawn around the earth equally distant from both poles, dividing the earth into northern and southern hemispheres and constituting the parallel of latitude 0°.

In March when the sun shines directly over the equator, the event is called the spring or vernal equinox. In September when the sun shines directly over the equator, the event is called the fall or autumnal equinox. 

The Autumnal Equinox will occur in Los Angeles, California, U.S.A. on Thursday, September 22, 2016. at 7:21 A.M.

Things to look for in fall:

1. Deciduous (di•si•jo͞o•əs) trees will change color and drop all their leaves. Evergreen trees will not. Evergreen trees will stay forever green. :-) Why do the leaves of deciduous trees change color? Use World Book Online to research. Remember, do NOT copy sentences. That is plagiarism, and it is against the law! Take notes, and then turn your notes into your own sentences.

2. On the equinox, there are exactly 12 hours of daylight and 12 hours of night. The day and night hours are equal. However, as we continue into fall, the days will get shorter and the night hours will get longer. This pattern will continue until we reach the winter solstice. That is the longest night of the year and marks a new season, winter.

3.  Because the northern hemisphere is now tilted away from the sun, the days will start to become cooler. People will change their behavior. What sorts of behavioral changes will your family make as the days get shorter and cooler?  (In southern California, we have mild climate. We don't get too cold in our community.)

There are many fall festivals or holidays. Watch the BrainPop video about fall to learn about the many harvest festivals celebrated. Do you celebrate any of these autumn holidays? If so, please share so we can learn from you!

4. Some animals in the northern hemisphere will change their behavior. As fall leads to winter, some animals migrate, or move, to a warmer area. Others try to fatten up for the winter they know is coming.

The first day of spring is called the 

Vernal Equinox. 

Spring started on Saturday, March 19, 2016, at 9:30 P.M. (PDT) in southern California. It is called the Vernal Equinox. There are two times when the sun is exactly above the equator. One equinox is in September and the other is in March. Equinox means equal night and there are nearly twelve hours of day and twelve hours of night.

Here is a video from Discovery Education to

help explain the Vernal Equinox!
