Three classes of Colorado fifth-graders recently received hands-on experience with archaeology, thanks to the passion of their teacher, Lindsey Mieras. The students wrapped up their study of archaeology, history and prehistory by working with U.S. Forestry Service employees to search for the remains of an old schoolhouse. "It's a multidiscipline field," Mieras said of archaeology. "They use math, writing, reading, history, science. It crosses all levels."
