We learned about light today and how it is made up of lots of different colors. This is an excellent activity for a preschooler! All you need is some dish soap, water, a straw and a container to put them in. Then go outside where it is sunny and blow bubbles and look for rainbows.
Daddy came while we were conducting the experiment and asked my 4 yr old. Is light straight when it comes from the sun? Apparently they had already had this conversation because she immediately answered no it is wavy. I was pleasantly surprised. Chalk one up for daddy!
When it gets a little warmer I plan on making some more rainbows by spraying water with the hose and seeing if I can make it work! My kids love this kind of thing! I didn't know that science projects could be so easy!
Here is a link for more on why you see rainbows in bubbles.

I told her that rainbows always have the same colors and they come in the same order. Below is the a picture of a rainbow showing the colors in order. She also drew a picture of mommy and told me a story about it. We then listened for the first sound in rainbow and she wrote it in the corner. All in all it was an easy and enjoyable afternoon of colors, rainbows, and letters and we were both happier afterwards!
I liked this article on how to explain to your child why the sky is blue and thought it went well with the rainbow and colors experiment we did here. Maybe one day I'll find a better place for it.
