HEMBACHTAL, Germany — Knowledge of ancient inventions and an early American cabal lifted Heidelberg High School to a 170-90 victory over SHAPE in the championship game of the 25th annual Academic Games conducted by the Department of Defense Dependents Schools-Europe

Heidelberg junior David Brunell correctly identified the Archimedes screw as a device invented for lifting water, and team captain Randall Bryan then identified the Conway Conspiracy as a plot to supplant George Washington as commander of the continental army to lock up the victory.

Heidelberg, runner-up to Ankara last year, beat out 26 schools in this two-day competition in which teams of four students attempt to be the first to answer toss-up questions covering subjects ranging from math, science and grammar to history, geography, literature and fine arts. Heidelberg was unbeaten in the pool-play, double-elimination event.

Completing the Heidelberg team in the final game were freshman Kevin Burdge and senior Samantha McQueen, the fifth member of her family, including her father, to compete in the event.
