An 8th grader at Keystone won national honors after putting her mom’s advice to the test.During the last academic year, Joanna Sohn’s mother added something new to her daily routine that didn’t sit well with the then middle schooler.“It originally started off because my mother forced me to eat probiotics daily,” Sohn said.Sohn had some doubts, which sparked the idea of a science project to hopefully prove mom wrong.“I wanted to investigate the effects of probiotics, metformin on ischemia, reperfusion injuries on roundworms,” Sohn said.Sohn wanted to determine whether probiotics were actually beneficial for her health, and she did it by using roundworms.“I treated the roundworms in three different timeframes: five days before hypoxia, two days before hypoxia and one day after hypoxia,” Sohn said. “Hypoxia is, like, where there isn’t any oxygen, basically. So I used nitrogen through a chamber.”Her science project is also testament to the young student’s resiliency and creativity.“There wasn’t a commercially available one at the school so, I had to make my own out of a Tupperware container,” Sohn said. “It was only one (Tupperware) because I put the C elegans (roundworms) in micro centrifuge tubes.”Then came the microscopic analysis that would help determine if she’d have to keep taking the probiotics.“I found that certain probiotics and concentrations of metformin had definitive and therapeutic effects,” Sohn said.When asked if the findings has convinced her to follow her mom’s advice, Sohn said, “Yeah, unfortunately.”Sohn continues to take her probiotics, which doctors say may help prevent ischemic or coronary heart disease, a disease Sohn said runs in her family.Her project, ""The Effect of Probiotics and Metformin on C. elegans after Treatment in a Hypoxia Chamber: Year II" was within the top 10 percent of regional and state science fairs, allowing Sohn to apply to the , a national STEM competition for middle schoolers. The competition is organized by the Broadcom Foundation and Society for Science &amp; the Public. Her project won her a $500 cash prize.“Our school has a long tradition of excelling in science fair, and Joanna is proudly representing it,” Edmund Tijerina, director of strategic marketing and communications for Keystone School said. “Joanna is the only one in the top 30 and she’s the only one in Texas (to be named a finalist). We’re just so happy and proud of Joanna.”Sohn’s future plans include becoming a doctor and competing in the final competition which is set to take place virtually from Oct. 16 through Oct. 21.Copyright 2020 by KSAT - All rights reserved.
