Oakley Campbell feared the worst when he got a call to come to Principal Lyn Rivet's office. Instead of punishment, however, Oakley was met with a big box from George Washington’s Mount Vernon Estate.

As a first grader at Sippican School, Oakley studied the country's first president for his class research project. Now a second grade student, he said he chose Washington "because he was the first."

Besides his part in the Revolutionary War, Washington's teeth proved to be the most interesting fact Oakley uncovered. Contrary to popular belief, the president's dentures weren't wooden, but cow bone and hippopotomous ivory (among other things) held together with barbed wire.

With his research, Oakley also discovered the George Washington Portrait Program, which provides schools with a framed print of Rembrandt Peale’s porthole portrait of George Washington.

Oakley wrote a letter to Rivet telling her some things he learned about Washington and encouraging her to the fill out a form to get a print donated.

She did, and last week the school received a box on its doorstep containing a framed 30 by 36-inch presidential print. Rivet and Oakley opened it together and decided to hang the print in the library.

On Thursday, Rivet honored Oakley for his initiative and encouraged students that research pays off.

"When you research things...you never know what other surprising things you're going to get," Rivet told the kids.
