This year we wanted to make even the choosing of the winners a learning experience. First, each correct entry was assigned a number. We corraled seven children as well as four PhysicsQuest volunteers. Each person flipped a coin. If the coin landed heads up we wrote down a "1" and if it landed on tails we wrote down a "0". A series of 1s and 0s forms a binary number. The binary number that was "flipped" corresponded to a correct entry and that entry was chosen as the grand prize winner. In this case the winning number was "00010111100" which corresponded to entry number 188, Ms. Aschim's 4th period class. Learn more about binary numbers
