bipolarity of molecules
(hydrophilic vs. hydrophobic properties)
Oh, and remember from my previous post mentioning the sweet, colorful treat Dr. Ann provided for my kiddos as also a part of the Colors of Chemistry? We enjoyed that this week also... colorful, tasty snow cones (the chemistry part... colors of dyes in the sweet syrup).
... and while my sixers happily shared their colorful tongues with each other and me, they would NOT pose for my camera so I could share them with you! Silly kids!
