Tri-Valley Science & Engineering Fair winners selected

Sweepstakes prizes go to Foothill, Amador Valley, Granada, Venture high school students

Some 305 local students in grades 7 through 12 from Pleasanton, Dublin, Danville, Livermore, San Ramon and Sunol competed for cash and other prizes at the 14th annual Tri-Valley Science and Engineering Fair (TVSEF) that closed Thursday.

Sponsored by Lawrence Livermore National Laboratory, judging took place Wednesday at the Robert Livermore Community Center in Livermore, with awards distributed during a ceremony there that evening.

More than 150 local scientists, engineers and science teachers served as fair judges, deliberating over this year's 201 project entries. The majority of judges represented the Livermore Laboratory. Science projects were judged on a wide range of criteria that represent standards of research held by the scientific community.

Sweepstakes winners in the senior division category were: Brian Cambra and Bryan Lent, 12th grade students from Livermore's Granada High School, who won in the team project category with their project, "Effects of Creatine Monohydrate on Mice."

Other winners are Evan O'Dorney, an 11th grade student from San Ramon's Venture High School, who won with his project, "Continued Fraction Convergents and Linear Fractional Transformations"; Rahul Doraiswami, an 11th grade student from Pleasanton's Foothill High School, who won for the project, "Cancer Diagnosis Using Metabolic Fingerprint Analysis,"; and Harikrishna Rallapalli, a 12th grade student from Pleasanton's Amador Valley High School, who won for his project, "Low-Cost Polarization Based GFP Viewer."

Winning in the junior division were: Riley Eldredge, an eighth grade student from Livermore's Christensen Middle School, who won for the project, "What's on Your Roof? A Study of Reflected Emissivity and Albedo From Roofing Panels,"; and Steven Wang and Paul Epperson, eighth grade students from Livermore Valley Charter School, who won for their project, "Creating an Energy Efficient Solar Powered Water Desalination Apparatus."

In addition, 68 special awards in the form of scholarships, cash prizes and other nonmonetary recognition were distributed from scientific, professional, industrial, education and government organizations.

Senior division sweepstakes winners of the fair will go on to compete in the Intel International Science and Engineering Fair, May 9-14, in San Jose. Junior division winners are eligible to compete at the State Science Fair.
