Alan Alda’s Message to Students:

How It Works

Each year we pick a new question students around the world want to see answered and hundreds of scientists send in entries in written or video form.

The Flame Challenge began in 2012 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 in 2013 (“What is Time?”), and that it was fun to see how scientists around the world answered “that one” in everyday language.

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.
