President Obama recently hosted the fifth annual White House Science Fair [2], an event that showcases innovative designs, projects, and experiments from students across the country. With students from a wide range of science, technology, engineering, and math (STEM) competitions, this year's fair also included a specific focus on girls and women who are excelling in STEM [3] and inspiring the next generation with their work.

Obama toured three dozen exhibits, but it was a group of 6-year-old Supergirls [4] who really grabbed his attention, NBC reports [5].

The Supergirls are a group of Girl Scout Daisies from Girl Scouts of Eastern Oklahoma who invented a seriously impressive gadget — a battery-powered page-turner for people with arthritis, people who are paralyzed, or "people who have no arms." The spinning contraption turns pages on its own and is made of Lego blocks — genius!

Wearing red superhero capes over their Girl Scout uniforms, the girls proudly showed the president their design while reassuring him that "it's just a prototype," he recalled [7], amused at their tech-savvy language.

Anna Maria Chávez, CEO of Girl Scouts of the USA [8], said, "America has a huge opportunity for economic growth with girls' interest in science, technology, engineering, and math. When girls succeed, so does society. We all have a role to play in making girls feel supported and capable when it comes to involvement in STEM fields — and anything else they set their minds to and have traditionally been steered away from."
