Proving and Disproving Hypotheses at the Holy Cross Annual Science Fair

The gymnasium of Holy Cross Regional Catholic School was filled with row upon row of innovative SCIENCE on January 8, 2015.
            Each of the grades were invited to participate in Holy Cross’s annual science fair, and this year did not fail to impress the faculty, parents, fellow-students and science pundits within the local community.  Grand prizes were award to each of the classes from pre-Kindergarten up to 8th grade!
Caroline McCabe (pre-K) had a wonderful demonstration of the scientific method implementing it to support her hypothesis that Santa Pooh Bear was in fact the largest of her stuffed animals.  Caroline’s brother (Ryan McCabe – 1st grade) also used his science skills to prove that the color of the sky can in fact predict the incidence of rain, giving scientific merit to the saying ‘Red sky at night, sailor’s delight.’
The Yacovelli twins (Gabriella & William; 4th grade) proved that levers can help decrease the amount of effort needed to do work, simultaneously demonstrating the difference between kinetic and potential energy.  Anna Marie Patti & Kelly O’Connor (5th grade) were shocked to find that the jelly-filled donuts slid down the slide at the same rate as the light French crueler.   They concluded that mass does not affect the rate at which something falls, supporting Newton’s 2nd law.
            Have you ever wondered if talking on your cell phone could in fact be detrimental to your brain development?  Casey Cowan (6th grade) proved that the radiation emitted from a Wi-Fi router did directly impacted plant growth.  In fact, the plant closest to the router died.   Star gazing enthusiasts may have wondered why they get such a vivid picture of their favorite bursts of light when the moon is in it’s new and/or half phases.  Michael Cunningham (6th grade) used physics to prove that the light from the moon had a direct impact on the visibility of the stars in the night sky.
            Not only can Holy Cross students perform high level experiments (7th grade) Olivia Carton constructed her own conductance sensor and subsequent conductance circuit to determine the best sports drink to replenish the body’s electrolytes.  Olivia found a simple homemade concoction and orange juice faired better then the more expensive store-bought brands.
            To further enhance the students’ love of science, Holy Cross was awarded a substantial grant to purchase new and innovative laboratory equipment to be used within their science lab.  Much of this equipment has been installed and the students cannot wait to get their “hands on” more science.
            All grand prize winning projects are on display at Holy Cross Regional Catholic School, available for viewing on Sunday, January 25th during the Open House from 10- 11:30 AM.  Holy Cross is located at 701 Locust Street, Collegeville PA.  Call 610.489.9434 for more information, or visit the website at
