Riley County high-school-age students gathered at Manhattan High School Wednesday to compete in the fifth annual Youth Entrepreneurship Challenge. The event gave local students an opportunity to show off their business ideas and presentation skills to a panel of judges. “I kind of liken it to Shark Tank for high-school-age students,” John Jobe, K-State Research and Extension agent, said. “Winners can actually take home some prize money.” Cash prizes were awarded to the top-three placers and a “People’s Choice Trade Show Award.” Participants were judged on their executive summary/business plan, formal presentation and trade-show presentation.
