Kristen Wehner, 13, of Beavercreek, received a superior rating for her project in microbiology. Her project consisted of growing bacteria from doorknobs in petri dishes. Wehner kept the bacteria at room temperature in moist and dry environments and photographed the growth each night for a week.
“It was fun watching it grow, it was pretty gross,” Wehner said.
In the end, Wehner found that being in a moist or dry environment was inconclusive in advancing growth. The most important factor was how often the doorknob was used.
Ann Wehner, mother of four, said she is proud of her daughter’s accomplishment.
Kristen Wehner said she wants to be a surgeon when she grows up and plans to attend either Carroll or Beavercreek High School.
