Where Do Rainbows Come From?

Often before I introduce a concept and teach them the "real" reason for something, I ask the kiddos to write about a creative reason why something happens. Why are flamingos pink? What happened to the dinosaurs? I ask them to really stretch their imaginations and come up with something unique, even if they already do know the science behind it. This is writing about rainbows-I believe my favorite one is that they come from Candyland-sounds plausible to me! :)
