Students, families and teachers browse the science fair displays at John F. Kennedy Middle School Thursday night. Projects included making a citrus fruit battery, determining which soccer ball has the biggest bounce, and memory tests.

John F. Kennedy Middle School Principal Angelo Campagnano plays the game “Plinko” during the school’s Fourth Annual Probability Fair held on April 8 and 9 in the school's gymnasium. The game was created by students Brooke Cochrane, Marisa Caruso, Rachel Flodquist and Megan Ritchie. All seventh-grade students were required to produce a game of probability and complete a detailed report as a performance task in the Connected Mathematics Program. Through the guidance of math teachers Amy Perry, Elizabeth Sterner and Barbara Jarosz, the fair was a big hit with the students, school officials said.
