Oct. 19 - President Obama has launched an "Educate to Innovate" campaign to improve the participation and performance of America's students in science, technology, engineering, and mathematics. As part of that campaign, middle school and high school students from across the U.S. displayed their award-winning science fair projects at the White House on Oct. 18. From a robot that plays soccer and a smart toilet that conserves water to an innovative approach to treating cancer, these student projects represent most cutting edge science, technology and engineering.
