Earlier this month, MEM-C brought materials science–in the form of milk–to Echo Lake Elementary! The colorful (and slightly gross) activity involves milk, food dye, and dishsoap. It shows how the consituents of the milk (esp. the fats) are affected by soap! MEM-C graduate students William Bittner (Stoll Group), Eric Lester (Cobden Group) and Xueta Ma (Yankowitz Group) volunteered their time and Echo Lake PTA reported that they counted 253 students (and an estimated total of ~430 people) attending the event!
