It's spring, and we have been studying rainbows! I personally love rainbows, as do my kids; they are almost magical even when you know the science behind them. We had tons of fun finding different ways to make them too!
Of course we already knew that rainbows occur when light is refracted by water droplets in the air. Well, I knew that, but my kids basically knew they appeared when there was rain and sun. They also know the colors well and still to this day (although they are 5 and 6 and haven't watched it in years) sing the Rainbow Color Song from Mickey Mouse Clubhouse!
They also remembered one of their favorite ways to make rainbows is with the hose in the summer! Simply hold the hose up where the sun can shine through the water and look for your rainbow. Make sure the sun is brightly shining behind you and move your hose slightly until you find the rainbow!
The next way we found to make a rainbow is a well known one, a prism. Prisms separate white light into its colors. We had a little plastic prism that worked with bright light, but it was even better demonstrated with the cut glass on Mimi's front door!

The next way we found was using a glass of water and a bright window. Fill the glass up part way and set in front of the window where the sun is shining in. We used a smooth glass and got a nice little rainbow, and then we used a faceted glass and got some crazy rainbows. Inspiration Laboratories was able to do this with a flashlight as well, but I guess ours wasn't strong enough! We'll have to try again someday!
The fourth way we found, and also my kids favorite, was using a CD. It worked well in the sunlight, but we had even more fun with it in the dark with a flashlight!
The girls played with so many different angles. The best was when Nadia managed to shine the rainbow on herself and couldn't find it! Buggy and Buddy made similar rainbow reflections; check out the patterns they made too!
The last place we found rainbows was in bubbles! Obviously we didn't actually make these rainbows, but we had a great time blowing bubbles and observing the rainbows in the membrane of the bubble! The thinker the bubble the more vibrant the rainbow!
If we had some oily puddles around to look at that would have been fun too, but it was currently too dry for that! We had a great time finding all the rainbows we did though!
