Fall Into Autumn!

  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?

  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, 202w, at 6:03 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! 

Check out the FREE BrainPop video about Fall. 

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. 

Again, BrainPop Jr. has a FREE video about fall. 


Share some fun facts about fall!

If you are in the southern hemisphere, tell us what season you are enjoying! How are you changing your behavior? 


  1. Dear Mrs. Yollis' class,

    I celebrate Thanksgiving in November. My favorite part of the feast is the delicious turkey. In addition, getting together with family makes me smile.

    Do you adore turkey too?


    1. Dear Blakey,

      I love turkey too! It's so good, and I ove it with mashed potatoes. Nothing is better than gravy on my mashed potatoes.

      How to you feel about cranberries?

      Your blogging buddy,

  2. Dear Blakey,

    It'ss Soy and Koush. We both love turkey. It's so delicious. Koush likes it with mashed potatoes and gravy.

    What do you like to do on Thanksgiving in Fall? Do you like to jump in leaves.

  3. Hello, we're a year 4 class from Foxton in New Zealand.
    We really liked how your blog post has lots of information. A fact we found interesting is that evergreen trees stay green.
    It's really interesting how in September you're going into winter and here in New Zealand we're going into summer. Our seasons are opposite to yours because we live on the other side of the equator.
    Do you have any more facts about the seasons?
    Can you tell us one cool thing about California?

    1. Hello Foxton, New Zealand! We were over the moon to get a comment from the Southern Hemisphere!

      You asked some questions about California. Guess what? We are going to do a post for you with lots of facts about California. Stay tuned!

      Mrs. Yollis' class

  4. Hello I am from Pennsylvania and found your blog and I love your blog I love all the pictures and slides especially the Turkey vacation story that’s the best Dec ———7- 2022
