— Brine shrimp, giant worms and smoked facemasks are among the 68 projects to be judged at the annual Sunnyside High School Science Fair on Saturday.

The projects, supervised by science teachers Joyce Stark and Teri Alvarez Ziegler, will be judged by 25 judges.

The judges will determine the grand prize winner, first-, second- and third-place finishers, Stark said.

This year, the teams have 60 freshmen and eight upper classmen.

Based on points, the top projects will advance to the 63rd Annual Mid-Columbia Regionals Science and Engineering Fair on March 9-10 at Columbia Center Mall in Kennewick.

Senior Elizabeth Ruldo, who last year experimented on different types of sheltering materials used in forest fires, is continuing that safety material theme.

Ruldo, who will be attending Penn State in September, is testing the enhancement of respiratory masks using plant, medicated and nano-particles compounds.

“I got the idea after all the smoke from regional forest fires in the valley that lingered for weeks last summer,” the four-year science fair student said.

Ruldo created a smoking box to test the types of masks people used last summer to see how many particulates pass through the fiber.

She recreated a breathing apparatus to test the filters. Late Thursday, she was still working on conclusions.

Stark said students will be working through this afternoon to complete projects and write conclusions.

Winners will be unveiled during a 7 p.m. Saturday ceremony in the high school library.
