Are you putting together a rainbow homeschool theme for your preschooler, kindergartner, or first grader? These activities will make great additions to your unit study! 

My darling baby (she’s in that fun age between a baby and a toddler) even jumped in on some of this hands-on play for our rainbow unit.

From rainbow science and STEM activities, to super fun sensory bins, here are my favorite rainbow activities for young kids. All of them provide the chance to talk about either how rainbows are formed, or the colors themselves, which makes a rainbow theme super versatile for larger families with kids ranging in ages.
