OMGGGG Make, explore and paint rainbows. Use a CD and sunlight or a flashlight to cast rainbows, study and paint with watercolors or color with markers or crayons. A great piece of process art for kids. Art and science, STEAM projects for preschoolers.
Alphabet Letter Match: This is a new one, but I couldn’t resist with the 2 halves of the rainbow it was too easy! So simple, cut the rainbows apart, then use as a capital/lowercase letter matching game!
