Alexandria Country Day School student Sebastian Pasanella was awarded first place overall in Division III’s Life Science category at the Fairfax County Science and Engineering Fair in May.  As a seventh grader, Pasanella studied how plant growth is affected by the properties of its water source, and found that water from the Potomac River provided the highest growth and lowest mortality rates for hydroponically grown plants. Pasanella’s classmate, Lily Donaldson, placed third overall in the Physical Science Category for her project studying whether a thermoelectric flashlight with an air-cooled system is more effective and efficient than a thermoelectric flashlight with a liquid-cooled system.  Donaldson and another ACDS student, Gabriela Selmonosky, were also given special awards from the Society for Industrial and Applied Mathematics at the Fair.  At the conclusion of the Fair, six students, including Pasanella and Donaldson, were chosen to represent our region at the Broadcom MASTERS (Math, Applied Science, Technology and Engineering Rising Stars) competition.  “I am exceedingly proud of Sebastian, Lily, and Gabriela.” said Scott Baytosh, Head of School. “Their work is a credit to their dedication and effort, and it is emblematic of the kind of critical thinking and communication skills that distinguish ACDS students.”
