To win a Young Scientist Scholarship at the Intel International Science and Engineering Fair, you've gotta be smart ... scratch that, brilliant. Brilliant, like WHOA! So what did Sara Rose Langbert, 17, do to win such an honor? She created a project called "Petrology, Morphology and Geochemistry of the Southern Juan de Fuca Ridge: Evidence for Off-Axis Volcanism." Sara conducted chemical investigations, ran a mathematical simulation and studied video of the ocean floor to explain the distinct features of Earth's most active volcanic regions. "I studied the shiny glass surface of rock samples, where magma instantly freezes when it hits ice-cold ocean water," Sara explains. Sara scored $50,000 for studying those rocks. Now a high-school senior, she spent the summer in an internship at University of Florida's Department of Geological Sciences, continuing work on her project. Intense.
