Rocking Rainbows

This morning while we were playing with the hose something neat happened.  The sun was shining behind us, went through the water and made a rainbow.  This made us wonder how rainbows were made.  After we were finished playing outside we looked up kid friendly videos to answer our question.  We found a great site at Sci Show Kids on youtube:

We learned that all the colours of the rainbow are already in the sunlight but mixed together.  When the sunlight moves through the water it bends and the colours separate making a rainbow.  This action is called refraction.  We learned that you can also make a rainbow by putting water in a glass and putting it in the sunlight.

After we were finished with our science experiments we decided to draw rainbows!
I showed my kids that there are different types of lines you can experiment with...although Merryn opted to go with the standard curvy line for her rainbow. When Merryn was done she wrote about what she learned.  This was such a fun lesson for everyone.  We also sang a couple of rainbow songs together!
Here are our favourites:
