From changing the world to chilling over pizza, science clubs at the University of Arizona play a major role in campus life.

The UA is home to nearly as many science clubs as there are science majors. The clubs are devoted to astronomy, medicine, neuroscience, surgery, optics, engineering, pre-veterinary science, pre-pharmacy, environmental science, anthropology, psychology, meditation, chemistry, aeronautics and astronautics, just to name a few. 

Engineers Without Borders at the UA, or EWB-UA, is a branch group of a national organization, EWB-USA, which in turn is affiliated with the international association, Engineers Without Borders - International. EWB-USA works to support "community-driven development programs worldwide through the design and implementation of sustainable engineering projects while fostering responsible leadership."

"You help one person, and they want to help other people -- there's just a chain reaction," said Lauren Case, a civil engineering senior and president of EWB-UA. She sees the group's purpose as envisioning "a world where all people have their basic needs" met.
