Dr. Heiman-real-life-adventureman spoke with us about his adventures as a geologist today! He's repelled out of a helicopter, been chased by a bear, administered 27 stitches on his own leg and then hiked for many miles, been bitten by a rattlesnake -- while holding on a steep cliff and camped alone for a month! And we thought geologist spent his career in an air conditioned office.

Dispersion
Lisandrea, Jana, Diane and Nancy acted out a fat molecule that becomes emulsified by soap today. Our brilliant moms, lead by Jana, locked arms as a happy fat molecule. Then the dressed-in-black soap, Nancy, brust through their happy molecule and sent the moms out into the vast bowl of milk. A truly Emmy-worthy performance.



Dispersion
We discussed dispersion today. We first poured milk into plates and dropped spots of food coloring into the milk. We observed that the food coloring did not disperse but stayed in colorful blobs in the milk. Then we dropped one drop of dish soap into our plates. Instantly the fat molecules in the milk dispersed allowing the water-based food color to move around the whole plate, mix with the other blobs of color and form ribbons and designs in our plates!
