Cardinal Joseph Bernardin Catholic School seventh-grader Grace Rost, of Orland Park, recently took third place in the Mother McAuley Science Fair.
Projects were broken into two divisions: investigation and invention. Rost’s project was an investigation on the subject of hydroponics. She tested to see whether a hydroponic environment promotes more vigorous growth in sunflowers than a soil environment.
“I came up with this idea when my parents gave me a hydroponics kit for my birthday,” Rost said.
“I was very impressed with the quality of Grace Rost’s project on hydroponics,” said Roz Iasillo, Mother McAuley’s science department chairwoman. “Grace’s presentation, explanation of her work and thoughtful answers to the judges’ questions were wonderful examples of her confidence in the subject area.
“As a budding female scientist, her drive to always do her best demonstrates the type of attitude that we nurture in our young women at McAuley. We were happy to recognize Grace’s investigation as one of the best.”
Rost also tested to see which hydroponic mineral promotes the most vigorous growth in plants.
“The minerals I used were magnesium sulfate, ferric chloride, potassium phosphate and potassium nitrate,” Rost said. “This was a great experience, and I recommend other students participate next year.”
