Watch the IREX World Smarts STEM Challenge Contest and Showcase. The event occurred on March 18, 2017.

The Contest and Showcase was the culminating event of the World Smarts STEM Challenge. Four months ago, 17 binational teams composed of over 250 high school students from the US and Ghana embarked on a collaborative virtual exchange to discover and create innovative STEM solutions to the following challenges:

  • defend your community against hazardous waste or
  • repower your community's energy use.

Team concepts were put on display through the World Smarts Virtual STEM Fair. A selection committee and IREX representatives chose the finalists from the Virtual STEM Fair submissions. Learn more about the World Smarts STEM Challenge »

The Contest and Showcase featured a contest between the finalist and runner-up teams for the grand prize. Binational teams composed of Ghanaian and US high school students presented their prototypes and concepts at the event to a panel of expert judges.
