Three Hillsboro High School students will compete at a Technology Student Association national convention after placing first in four events at the state level. The students competed April 16-18 in Salina.

Junior Amanda Roble won first in promotional graphic, designing promotional artwork for TSA.

Freshman Nicholas Ediger placed first in flight endurance. Competitors designed and constructed rubber band-powered planes. The planes had to leave the ground on their own power, and planes that remained aloft the longest won.

Freshman Aaron Slater won the dragster design contest. He designed and built a carbon dioxide-powered car for speed.

Ediger and Slater also won in structural engineering. They had two-and-one-half hours to build a truss with limited materials. Their truss won when it had the best ratio of weight supported to weight of the truss.

Teams of freshmen Ben Loewen and Evan Wienck and Ediger and Slater competed in technology problem solving, but didn’t place.

Team members will compete June 28-July 2 in Denver at national convention.
