RSD Students Earn Top Honors at 2026 Mid-Columbia Science Fair

RSD Students Earn Top Honors at 2026 Mid-Columbia Science Fair

More than a dozen RSD students earned awards at the 2026 Mid-Columbia Science and Engineering Fair. Three high school students, Hanford High junior Prayrona Choudhury, Richland High sophomore Akshath Motkuri and Richland High sophomore Aarav Shrivastava were named Grand Prize winners, earning them an expenses-paid ticket to compete in the Regeneron International Science & Engineering Fair later this year in Arizona. The students were commended for their creativity, hard work, perseverance, and the ability to take risks – attributes needed to solve the most pressing problems in the world. 

Students in grades 6-12 may compete in the fair by creating and carrying out a research project on a topic of their choosing. First place winners in grade 9 receive an expenses-paid trip to attend the Regeneron International Science and Engineering Fair as an observer and middle school division first place winners receive a scholarship to attend a week long residential STEM camp. Students were evaluated on their research project abstract, display slides, a scientific journal and overview video. Click here to learn more about the Mid-Columbia Science Fair.
