Autumn Equinox:: Au Revoir Summer!

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
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 Saturday, September 22, 2018 at 6:54 P.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.
Share some fun facts about fall! Did you use BrainPop or World Book Online as a reference?
If you were in the southern hemisphere, tell us what season you are enjoying right now. How are you changing your behavior?
Hi i'm Violette and I learned that some trees loose their leaves in fall to save energy for the cold winter.I also learned that many birds migrate in a v shape to reduce air that drags against them.This helps the bird save energy.Do you like fall? What is your favorite season?
ReplyDeleteDear Violette, Our favorite season is Winter because we like the cold fluffy snow that lays on the ground.We also like the holidays in Winter like New Year. Did you know our birthdays are in the Winter? When is your birthday and what season is it in?
DeleteIt is now spring in the southern hemisphere. I would be playing outside more, it's warmer and the sun is out longer. My favorite season is summer, because I'm outside a lot and I swim often.
ReplyDeleteMs. Tulbure,
ReplyDeleteI used Brain Pop, Jr. I learned that some trees don't change color in the fall. I actually didn't know that some animals took shelter in the fall. I found that interesting because I thought that most animals migrate in the fall. My life is different in the fall because my soccer practices are earlier because it gets darker faster.
From,
Wyatt
Hi I'm Benny. My favorite season is Fall because I can go out on Halloween night with my costume on. I knock on a lot of doors and say "trick or treat!" and get a lot of candy. I love candy. YUMMY YUMMY!
ReplyDeleteDear class,we learned that in the fall many farmers reap their crops before the winter arrives.It gets darker so we have to sleep earlier because our parents think it is getting late.What traditions do you celebrate in the fall?What have you learned in the brain pop?
