The 13th annual Martha’s Vineyard Regional High School science fair took place Saturday morning, with freshmen Lee Faraca and Gordon Moore winning the grand prize for their project Cost Efficiency: Solar vs Wind Energy.

“We tried not to expect anything,” Gordon said afterward. “We didn’t think we were going to win.”

Lee and Gordon were also awarded first prize in the environmental science division and took home the David Brand award for “an outstanding project related to earth science.”

Junior Jack Wallace won second place overall for the development of a mobile application, entitled Homework Buddy. Jack was first in the engineering design, product-based division.

Junior Charlotte Hall took third overall and first in the engineering design, process-based division for her project, Ceramic Glazes: Chemistry and Art Combined at High Fire.

One hundred and fifty projects, a school record, were entered in the fair.
