SALT LAKE CITY — Two all-girl teams, one from Granite Park Junior High School and one from Cottonwood High School, took top prizes from the 2014 MESA USA National Engineering Design Competition recently held in Portland, Ore.

The competition involved developing a prosthetic limb for less than $40 to help children in developing countries who have lost a wrist and hand.

The Granite Park team, Aruna Dhungel, Dipika Dulal, Syeda Hashmi, and Rekha Subba, won the overall middle school third-place trophy. The middle school competition required a 15-page technical paper, a poster, a 10-minute oral presentation, two timed performance tasks: ball toss and object relocation, and an overall design efficiency category. The girls placed first for their technical paper and third for object relocation in addition to their trophy.

The Cottonwood team, Hawa Dahir, Asmisha Dulal, Margaret Mathew and Natalene Rehan, won the third-place medal for design efficiency in the high school competition.

The Utah teams competed against 39,000 students from nine states just to be included among the nine high school and eight middle school teams to compete in Portland on June 19-22.
