This year's theme was "Building a Better Future." At the conference, girls participated in hands-on workshops, special group activities and a career fair.
The conference also provides the students with opportunities to meet and interact with positive role models who are actively engaged in math and science-related careers.
The conference was coordinated by volunteers from Lawrence Livermore National Laboratory, Sandia National Laboratories/California, Las Positas College and the Association of University Women.
