Lindsay Geschickter and Daniel Genlot are captivated by the result of their dry ice experiment in Barbara Leparulo’s science class at Edison Intermediate School in Westfield.  Ms. Leparulo and Ms. Squillace, both veteran science teachers at the school, conducted the dry ice lesson to demonstrate how some solids can skip the liquid state and go directly to the gas state.  Throughout the day in sixth grade science classrooms, gloved students dropped the dry ice into a half glass of water and watched as it produced carbon dioxide.  Other experiments with the CO2 included snuffing out a candle, expanding a balloon, and watching a bubble float on top of dry ice.   Students were also instructed to record their observations on sublimation.  The teachers thanked the family of Danielle Ardente for the donation of the dry ice.
