For African-American History Month, the fourth-graders of Carmen Dufresne and Molly Dorner at Pettingill School in Lewiston completed a unit studying the achievements of African-Americans. The students researched and wrote reports, constructed life-size posters and presented oral reports before parents and classmates. In addition, they sent pictures of their posters and wrote about their African-Americans to their New Hampshire pen pals. Pictured are twins, Izrael and Jordan Farrell. Izrael researched the inventor of the sugar refiner, Norbert Rillieux, and Jordan researched the first black American Roman Catholic bishop, James Augustine Healy.
