This year’s Flame Challenge, started by actor and science proponent Alan Alda as a way to engage kids in science, asked scientists to explain “What is Color” to 11-year-olds. Hundreds submitted answers and winners were determined by 27,000 11-year-olds from 19 countries. The “What is Color” event at the 2014 World Science Festival concluded with the awarding of the winners and also featured three scientists examining color from unique angles. Video presentations of “What is Color” and other events as well as more information about the World Science Festival, an annual celebration and exploration of science, can be found here.
