Sam Wilsdorf, 13, explains his project Friday morning to associate professor Zahra Afrasiabi, left, and professional engineer Ross Kasmann during the 30th annual Lincoln University Regional Science Fair in Jason Gymnasium. Wilsdorf, a seventh-grader at St. Patrick’s School in Rolla, measured the voltage of several types of food. “The potato didn’t actually do that well,” Wilsdorf said of the vegetable which is sometimes seen powering a light bulb. He found a red apple to have the most voltage. A lime, pickle and lemon also produced more voltage than the potato.

Russellville sixth-graders, from left, Harrison Frank, Kyle Brautigam and Josh Behrens wait for their projects to be judged during the science fair. Frank and Brautigam constructed a catapult to test golf ball brands for flight distance, and Behrens teamed with Tristin Little to test the effect different voltages have on hydrogen production in a hydrogen fuel cell. Russellviille Middle School was one of eight middle schools and eight high schools in the competition.
The rain didn’t dampen spirits of eager students and equally enthusiastic judges Friday at the 30th Annual Lincoln University Regional Science & Engineering Fair in Jefferson City.
Russellville Schools sixth-graders Makayla Stubinger and Brianna McKinney were hoping for another blue ribbon for their project “Effect of the Type of Liquid on the Growth of the Soybean.”
To bring their projects to the regional fair, students from Russellville first compete at the school level. The girls were among 15 sixth-grade science teacher Tom Backes brought Friday.
