YHS seeking judges for Science and Engineering Expo

Yuma High School is seeking judges for its annual Science and Engineering Expo, which takes place Dec. 14 from 8-11:45 a.m. in the school library.

“Every year Yuma High School holds science and engineering expo, previously called a science fair,” YHS Science Teacher Marelis Rivera said. “Students will present work on topics of their own choosing that they have worked on during the fall semester.” 

Members of the community can sign up to judge by using the following form:

During the expo, science and engineering students share projects from one of seven categories: chemistry/biochemistry, environmental science, zoology, botany, engineering/technology, health/medicine, and physics.

Judging consists of viewing the students’ posters and reading their research papers and lab narratives before they arrive. Judges will have the opportunity to interview participants about their project as well. According to Rivera, the purpose of the interviews is to make this scientific process as authentic as possible and to allow judges to score projects and therefore choose the top three in each category. Most categories are finished well before 11 a.m.  All judges will work together to select the top three projects in the fair by interviewing all category winners. 

Last year, Yuma High competed at the County level where they received three awards and at the regional Southern Arizona Research, Science and Engineering Fair in which we had five teams win top awards. One student was selected for the honor of attending the Intel International Science and Engineering Fair in Pittsburgh.
