2014 USA Science and Engineering Festival (Image 34)

July 3, 2014
Visitors at the Twin Cities Public Television show "SciGirls" exhibit "Music is the Sound of Physics" at the 2014 USA Science and Engineering Festival design and create a pan flute using scientific principles and measurements. The exhibit used the ancient wind instrument to demonstrate how physics and math underlie nearly all of music making. Visitors also explored sounds using tubes of various lengths, saw how design affects the sound-wave frequency and air vibration, and could even partner together to arrange a collection of different-length tubes into a giant xylophone. The exhibit was one of the National Science Foundation's (NSF) exhibits and stage shows at the festival that took place at the Walter E. Washington Convention Center in Washington, D.C., on April 25-27. NSF was a partner in the festival, the nations largest celebration of science and engineering, where visitors eagerly engaged in hands-on activities and were amazed by the breadth of research and education projects supported by the agency. The festival expo provides an opportunity for NSF to showcase the innovation the agency supports throughout the U.S. and the projects and programs selected to represent NSF benefit from the opportunity to demonstrate the value of their activities and outcomes to a large national audience. The goal of the festival is to reinvigorate the interest of the nations youth in science, technology, engineering and math by presenting these areas in an exciting, compelling, educational and entertaining manner. Now in its third year, the festival attracted an estimated 320,000 attendees. (Date of Image: 2014) Credit: Susan Pell, National Science Foundation
