Jaclyn Onufrey has made history at Wantagh High School.

The senior was the school's first-ever semifinalist in the Intel Science Talent Search. Her project explored the invasion of Asian shore crabs in the eastern United States.

She was among 51 students from Long Island to earn the designation earlier this month, along with a $1,000 college scholarship and $1,000 for her school's science program.

"I'm very proud to represent Wantagh," said Onufrey, 17, who worked on the project for a year with LIU Post ecology professor April Blakeslee. "It means a lot to be the first in my school to get it."

Onufrey also is captain of her school's Science Olympiad team and a member of the Rube Goldberg team, which has won first place for three consecutive years in the Rube Goldberg Machine Contest. The competition challenges teams to create a contraption that can complete a simple task through a series of chain reactions.

In other school activities, Onufrey is Wantagh's drum major and a member of the wind ensemble and the Tri-M Music Society. She also is in mathletes, Key Club and the Foreign Language Society and serves as secretary of the high school's National Honor Society chapter.

Four semifinalists from Long Island are among 40 finalists nationwide in this year's Intel competition and will compete for top prizes in March in Washington, D.C. The finalists were announced Wednesday.
