Students in grades four through 12 from Carlisle Area and South Middleton school districts, Bethel Christian Academy, Christian School of Grace Baptist Church and St. Patrick's School displayed projects at the fair. Courtney Hair's project developed out of her interest in horseback riding and a need to know when her horse was sufficiently cooled down after a workout. After testing 10 different horses, she concluded that it takes a horse 15 minutes to return to its normal heart rate after exercising. Now, every time I ride, I will know when my pony is cooled down. She tested several different heights and materials for sound barriers before discovering that 12-foot wooden walls did the best job at keeping noise away from nearby neighborhoods.
Inventions are science and everything is an invention.
Scott Brookens, a fourth-grader at Iron Forge, said he enjoyed working on his first entry in the science fair. Foltz led Snyder down the school hallway and out the door. The arrest was captured by a live video camera and broadcast over the school's Lion TV morning announcements, which are seen in every classroom on a television monitor. Other scenes of Snyder in his jail cell at the Middlesex Township police station had been videotaped before the arrest. That footage had been shown on the morning broadcasts before Snyder's arrest.
