Some Examples of Children’s “Main Rainbows”

This rainbow was painted for Grandma by Mia when she was 4 years old. It is a "Main Rainbow" because Mia was just learning about rainbow order.  She practiced and practiced using all kinds of colors. . . . she used crayons and colored pencils and even magic-markers!

 red

          orange

                       yellow

                                  green

                                              blue

                                                        violet

However, this was her first PAINTING using color this way.  She used tempera paint because it is paint that cleans up with water.  

This painting is "frame-able" because it is more than a painting.  It is also a beautiful example of Mia’s learning.  It is an example of her learning and understanding that everyone else can SEE.  And she doesn’t even have to write words so that we can know what Mia learned about science, rainbows and color. 

You can learn and practice how to make a "rainbow" using color in the correct order. Then choose one of your best rainbow picture and have someone help you frame it as your very own learning.

Here are two more examples of Mia’s younger friends using the same process of learning, practicing and then choosing a “main rainbow”.  All three of these rainbow pictures are framed!

Mia’s friend Penny learned about Rainbow order when she was three years old.  This magic-marker drawing was done soon after she learned how to hold a marker and make marks.  Note how each color is heavier on the left side of the paper where she began each line.                                                                                                               

Walt saw the rainbows done by his friends Mia and Penny.  He understood rainbows already.  “It’s easy”he thought to himself.  All you have to do is go in order:

red

      orange

                  yellow

                             green

                                         blue

                                                  violet               

When the paint was ready, he too made a rainbow painting that Grandma framed as “Walt’s Main Rainbow”.

Have mom or dad or grandma or grandpa or the person who takes care of you send me a .jpeg file of your rainbow picture—they will know what that is.  They can send it to:  grandmarainbow@gmail.com

Grandma Rainbow, How A Rainbow is Made by Nature

COLOR!

“Emancipate the Rainbow”

          Color is the part of light that we can see.  The range of visible light waves goes from red to violet  (note: violet and purple are different names for the same color that we see).  Light waves that we can't see are infra-red and ultra-violet.

The rainbow is a reflection of the sun’s light waves bouncing off of raindrops.  

Light travels in waves. The light's wavelength determines its color. Short wavelength light, for example, appears blue, and long wavelength light appears red.

When light strikes particles that are larger than its wavelength, the light's path may be altered. When light strikes particles that are smaller than its wavelength, the light continues to travel unaffected.

The atmosphere contains many particles and gases, mainly nitrogen and oxygen.

Sunlight is composed of light of many different wavelengths. Longer wavelength light appears red, orange, and yellow, while shorter wavelength light appears blue, indigo and violet. The gas molecules in the atmosphere scatter, in all directions, shorter wavelength light (e.g., blue). The longer wavelength light (e.g., red) is largely unaffected by the atmosphere. As a result, when you look at the sky, you see the blue portion of the sun's light being scattered by the atmosphere. If you were to look at the sky while standing on the moon, you would see a very bright star surrounded by complete darkness. This is because the moon has no atmosphere and so sunlight is not scattered.

Grandma's Rainbow from Her Front Porch.

This is GrandMa's Rainbow which is always right in front of GrandMa's porch and it comes to me every day looking for your Art!  It know that I have to have some art from you, my friend.  They just knew it would be beautiful because of all the colors that I have on my front porch. The next thing I want to do is give you a lesson on how to make rainbows.
