Ball State's last Electronic Field Trip of the year, "Exploring Carlsbad Cavern: A Journey Through Nature's Plumbing System," took students and viewers from 49 states on a virtual tour of Carlsbad Cavern in New Mexico. President Jo Ann Gora Gora and First Lady Laura Bush conducted a science experiment live from the Charlestown Navy Yard in Boston. The experiment used clay, sugar cubes and water to demonstrate how caverns like the one in Carlsbad form, Outreach Programs Director Mark Kornmann said.
During the segment Cowan Elementary School fourth grader Hayley Hunter had the opportunity to ask Bush a question. The 10-year-old asked Bush what her favorite national park was. Bush said she liked the Grand Canyon.
