 This is Ozarks at Large. Last year, Matthew Holden, a science teacher at Fayetteville High School, and Brittany Berry, a teacher at Helen Tyson Middle School in Springdale, were selected for the Grosvenor Fellowship from the National Geographic Society. As part of their fellowship, both teachers traveled to Antarctica for an expedition led by National Geographic over their winter break. Holden and Berry are back home and bringing what they learned into the classroom.
