Rainbow in a storm…

Easy, quick science exploration to go along with the building-a-rainbow one that didn’t work.

This doesn’t really demonstrate any of the scientific principles we’ve been learning about (“all colours of light are contained within white light”), but it’s easy and quick and a bit impressive to watch.  You could use it for an art class on colour mixing, as well.  (here’s another quick and easy colour-mixing art project we did a while back)

Scroll down to see the steps here (“Milk and Rainbows”).

And here’s the one that didn’t work, which we got from Mr Q Science, but which I looked up online because he doesn’t give a picture.  Looks quick and easy, and we even have a big glass pan.  But our flashlight is the wrong kind – it has several smaller LEDs instead of one big steady beam.  It doesn’t cast a light beam so much as emit unfocussed pale light in every possible direction.  :-(

(and it’s the only one in the house that I could find)

I’m trying to teach the kids that even when our science experiments (“explorations”) don’t work, it doesn’t disprove the scientific principle we’re investigating – it only proves how UN-scientific our environment is.  But sometimes, when I have done absolutely everything right… well, it’s frustrating.  Can’t scream because I’ve lost my voice.  Can’t throw things because every muscle aches.  Drat, I hate homeschooling with a cold.  :-(

Are you perennially foiled by science?  Or is there another homeschool subject you just can’t seem to “get to work”???
