This week, we spoke to two teams who scientific acumen brought them all the way to the White House for the nation's annual science fair. First in our series is an automotive technology class from James Logan High School in Union, California that built a charging station for solar cars.
Second is a team from Baruch College Campus High School in New York City that built a semi-automatic vacuum to ride on the back of subways to clean up trash.
Check out the White House's own video of the event and profiles of some students:
