Rainbow Prism Busy Bag

Everything’s coming up rainbows here this week.  We’re making Rainbow Slime.  And we’re splitting apart light into all of it’s glorious ROYGBIV-ness.  We’re playing with a Rainbow Prism Busy Bag.  This post contains affiliate links.

Kids can experience how prisms turn light into rainbows with a Rainbow Prism Busy Bag. It's an educational way to keep your little STEM-ist busy.

ROYGBIV Colors of the Rainbow

My childhood education had a major gap in it.  I never learned the acronym ROYGBIV.  I had learned the colors of the rainbow, even about that pesky indigo, but never called them ROYGBIV.  I remember chatting with someone my freshman year at MIT and I had to ask what it meant.  And so began the taunting.  (Yes, nerds can bully too.)  So I’m on a mission to make sure that my daughter learns it.  And what better way than through song?  And you know who sings about ROYGBIV the best?  They Might Be Giants :)  They have a whole album for kids called Here Comes Science {affiliate}.

Rainbow Prism Play

Now that my daughter and I had sung about it, it was time to create our own rainbows…  She tried it a few different ways for different effects.

I had put up some white foam core board for the teardrop prism to shine it’s rainbows on.  Then she pulled out the crayons and drawing her own rainbows.  I think the combo of the light, rainbows and large format were a huge hit. (Btw, I had nooo idea how hard it is to capture the rainbow from a prism with a camera. So the pictures definitely don’t do this activity justice!)

Then she took the triangular prism and flashlight into the dark.  Here the rainbows are a little more subtle but the play seemed more fun.  Probably because it involved a flashlight.  Are your kiddos as flashlight-loving as mine? But it also involved trial & error to figure out how to hold to flashlight to create different patterns of light.
