Eleven high school students from across South Africa have joined 1 700 learners from 75 different countries to compete at the 2015 Intel International Science and Engineering Fair (ISEF).
ISEF is an annual science fair where young scientists from around the world can showcase the innovations that saw them win national science fairs in their home countries.
The winner of the $75 000 (about R900 000) Gordon E Moore Award will be announced this Friday, the 15th May.
“Time will tell if one of the African countries will nab the prize, and the glory,” Intel said.
The following South African learners join 26 other teenagers from Kenya, Nigeria and Egypt, who are also representing Africa at the competition.
