Both schools will host dance marathons to raise money for charity.
Money collected at UNC will support the N.C. Children's Hospital, while money at Penn State will benefit the Four Diamonds Fund, an organization devoted to funding research on childhood cancer.
Started in 1998, the dance marathon is still relatively new to UNC students, but students at Penn State have been dancing for charity since 1973. Last year, they raised more than $3 million, according to the organization's Web site.
Christa Cavaluchi, entertainment chairwoman of the Penn State dance marathon, said it originally started as a 24-hour competition but has turned into a 48-hour marathon sponsored by the school's Interfraternity and Panhellenic councils.
Cavaluchi said she doesn't know the exact reason for the change. "I think the reason is because it is the longest," she said. "It's not documented why they decided to change from a competition."
Like UNC students, Cavaluchi said Penn State students raise money for the marathon by holding a 5K run and soliciting businesses.
She added that more than 250 campus organizations, including Greek organizations and the campus newspaper, also raise money.
She said planners hope that dancers can stay on their feet for the entire 48 hours.
UNC and Penn State are not the only two universities sponsoring dance marathons this year.
