rainbow science

This experiment was so easy to prep and so effective, I can't believe that I didn't do it with the kids years ago.



To prep, I went to my fridge for milk, to the sink for dish soap, the cupboard for food coloring and the bathroom drawer for q-tips.  So easy.  And a class set of bowls.  

The tricky part was getting 24 bowls with milk ready for 24 scientists without anyone spilling.  


The scientist worked very hard keeping all body parts off the table while I put a drop of red, blue and yellow food coloring in each bowl.  



Each scientist was given a q-tip covered in dish soap.

Very carefully, the scientists touched the food coloring with their q-tips and observed the results.  



The colors moved, and swirled and mixed with each other.  

The scientists kept "chasing" the colors with their q-tips.  



Twenty-four engaged scientists, observation, working together,  lots of good questions, a few what-would-happen-ifs, one happy teacher ...

And no split milk.
