Forensic engineer Jeffrey Pfaendtner helped the student learn to use the trebuchet and the different ways to alter the flight of the apple using different math and physics experiments.

Deephaven 5th Grader Brooklyn Short writes down the results of her first foray with the trebuchet experiments outside Crane Engineering in Plymouth Tuesday, May 22, 2012. About 75 students traveled to Crane Engineering in Plymouth to learn alongside forensic engineers. These engineers piece different elements of science together to find answers…so if a piece of steel fails, or a gas explosion occurs, their engineers know how to find out “why.”
