Girls Make the Grade at the White House Science Fair.

Girls are coming to the White House on Tuesday and they are bringing their robots with them.

Dozens of kids from grade school to high school will be there for the White House Science Fair, launched by President Barack Obama in 2009. This year, the emphasis is on girls who excel in science, technology, engineering and math (STEM), fields where women are severely underrepresented in the workforce.

Shannon O’Brien, 17, was invited to the White House as an honored guest. She wants to be an engineer. If things don’t change, she will be outnumbered by men in the workplace by seven to one, according to 2011 statistics on engineering from the U.S. Department of Commerce.
