Rainbows are beautiful, but are often hard to find. Have you seen a rainbow in the sky?
Do you know the primary 7 colors that make up the rainbow? This song will help you to remember:
Red and yellow and pink and green Purple and orange and blue, I can sing a rainbow, Sing a rainbow, Sing a rainbow too. Listen with your ears, Listen with you eyes, And sing everything you see! I can sing a rainbow, Sing a rainbow Sing along with me...
You can make rainbows at home. You will need a glass bowl, a mirror (that fits inside the bowl), water and sunlight (or a torch if it’s dark). Stand the mirror inside the bowl, and fill the bowl about half way with water. Put the bowl in the sunlight with the mirror toward the sun, and reflect the rainbow onto a white wall or white paper. You might need to wait a while, or try different positions until you are able to find a rainbow.
Can you see the rainbow I made at home?
I caught the rainbow on some white paper
Once you’ve done that, you could take it outside, and see if you can project the rainbow onto a tree, your house, or anywhere else. Where did you put your rainbow?
I put mine in the sun outside, and projected a rainbow onto a gum tree. Can you see it?
Another way to make a rainbow is to use the silver side of a CD – put it in the sunlight and reflect it onto a wall or white paper.
I used a CD to make this rainbow
White light is made up of the 7 colors. When it goes through water or goes onto the CD, the white light is broken up so we can see each of the colors separately.
How can you make a rainbow? You might want to draw or paint one. You could use playdough, or different colored leaves and flowers.
You could even eat a rainbow!
