13-year-old Ghanaian scientist meets President Obama 13-year-old Ghanaian-American future scientist, Simon-Peter Frimpong, presented his robotic project to President Barack Obama at the White House on Wednesday. The 8th-grader from Aurora, Colorado, was one of over 100 top science, technology, engineering and math (STEM) students from across the USA who were invited to the 2016 White House Science Fair and got to meet President Obama. The fair is a hands-on showcase of student innovation – robots, prototypes, tools to help fight cancer and climate change – all researched, designed and built by young American scientists. Simon-Peter and two of his schoolmates from Horizon Middle School, Maya Max-Villard, 13, and Grayson Fast, 14, showcased a new artificial leg they designed and built using computer design and 3-D printing of prototypes. The three teenagers set to work and came up with the artificial leg that now allows the amputee to hike, manage uneven terrain and even skateboard. http://ameyawdebrah.com
