Since the first Science Bowl in 1993, LAUSD schools have taken home four first-place national titles and 10 times have placed in the top five, according to Walter Zeisl, the Los Angeles Department of Water and Power's Science Bowl coordinator.
A first-time entrant, the North Carolina School for Math and Science, took top honors, followed by Sacramento-area Mira Loma High School in second place, Zeisl said.

Arcadia High School came in fourth out of the 68 teams that competed, Zeisl said.
First lady Michelle Obama addressed the group as did Energy Secretary Steven Chu. At the middle school competition held concurrent with the high school contest, the first lady asked the students questions and Chu served as a science judge.
As a third-place winner, NoHo receives $1,000, special calculators and a lab-based computer system, Zeisl said.
The National Science Bowl is sponsored by the Department of Energy, and two teams, representing the city of Los Angeles and other schools in Los Angeles County, are sponsored by the Department of Water and Power.
