Little girls can grow up to be whatever they want, even astronauts.

That's why the "Girls Go Tech" program of the Girl Scouts of Northern California teamed up with NASA to host "When I Grow Up," a full day of activities to engage and encourage girls to enter careers in science, technology, engineering and math. The event took place on Saturday at the NASA Ames Research Center in Moffett Field.

During the event, girls between the ages of 5 and 18 participated in hands-on, science-related activities guided by scientists, engineers and researchers who represented a wide variety of fields at Ames and throughout the San Francisco Bay Area.

Though there weren't any cookies, there were definitely robots and airplanes.
