WASHINGTON — Some of America's brightest children will visit the White House as President Barack Obama holds his final science fair to highlight work that excelled in a broad range of competitions.
Obama began the science fair in 2010, saying the students who produce the best experiments and products ought to be recognized like the sports champions who regularly come to the White House.
The fair on Wednesday will feature more than 130 participants, including a Connecticut student who created a diagnostic test for the detection of the Ebola virus, a New York student who found a way to improve undersea cement seals to keep offshore oil wells from leaking, and a group of middle-school students from Colorado who created a more functional prosthetic for a local veteran.
