Overall my kids loved this rainbow science experiment and were fascinated to see their own rainbow grow.
We designated an afternoon of fun, learning about rainbows, and spending quality time together.
Prior to the project, we went to the library searching for rainbow-related books and I read them while the kids did their project. We talked about how rainbows are formed, learned about the different colors in the rainbow patterns, and all the amazing facts about them.
They also loved to hear all the different legends from all over the world. In the evening they showed daddy proud their activity and told them all about the facts they learned.
Now each time they see a rainbow they smile and remember our fun water rainbow experiment and like to repeat this cool marker paper towel experiment.
This science craft was a full success and is also suitable for classroom settings. It definitely makes the perfect preschool magic activity during a rainbow theme preschool week!
