Students of all ages, parents and educators at Calhoun High School shaved their heads for a cause on March 16.

The school's annual St. Baldrick's Foundation fundraiser brought in more than $30,000 to aid research into childhood cancers. The non-profit St. Baldrick's Foundation provided more than $12 million for research in 2009 alone.

Participants in a St. Baldrick's fundraiser shave their heads in "solidarity with kids fighting cancer" and collect pledges in return for taking it all off.
