How It Works

After screening for scientific accuracy, the entries are judged by thousands of 11-year-olds in schools around the world. The winning scientists are brought to New York to be honored in June at the World Science Festival. Entries can be written, video or graphic. For rules and other information, see the links at the right.

The Flame Challenge began two years ago with Alan Alda’s childhood query: What is a flame?

“When I asked what a flame was at the age of 11,” Alan said, “I was probably younger in some ways than most 11-year-olds are now.” He said the kids asked a very deep question last year (“What is Time?), and that it was fun to see how scientists around the world answered “that one” in everyday language.
