E-girls find lessons on aggregate in form of cookies Asphalt cookies anyone? Erika Bowen and Mary Lockwood led a group of female high school students through an exercise designed to demonstrate how a road surface is constructed as part of the annual e-Girls Workshop at Boise State University recently. Instead of the typical aggregates – crushed rock, sand and limestone dust or cement – the students worked with chopped walnuts, coconut and oats. For tar, the group used melted chocolate. The e-Girls workshop is a two-day summer program that explores engineering and computer science careers. It is designed for women who will be high school sophomores and juniors this fall.
