Past Challenges

Each year, students from around the world submit their questions as a challenge to scientists who wish to enter The Flame Challenge. Based on popularity, a team from the Alda Center selects an appropriate question and challenges scientists to submit written or visual entries that an 11-year-old would find interesting, understandable, and maybe even entertaining. 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.
