Not only that:
The portions on the visible spectrum tie right into art and the color wheel, and provide a hook to physics that kids who find science scary or unfamiliar -- a common occurrence, sadly -- will find harder to resist.
It's like teaching science with magic tricks, another fruitful approach, if one has the manual dexterity. I don't, but I have a wizard's hat. ;)
Thank you, Dan!
