EDISON – Sidharth Kumar of Parlin, a fourth grader at The Wardlaw-Hartridge School in Edison, snaps a photo of a leaf with an iPad during a fourth grade exercise. On Tuesday, Oct. 25, Ellen Colandrea’s fourth grade class took a leisurely nature walk around the W-H campus to observe the changing colors of the foliage and to collect samples of seeds and leaves that had recently fallen to the ground. The students have been learning about the process of photosynthesis as part of their plant unit in science. Two days later, the children worked in the lab to create rubbings of their specimens, which served as a review of the parts of a leaf. The last phase of the project involved using an app on their iPads called “Leafsnap.” After “snapping” a photograph of each leaf on a white background, within moments, a list appeared on the screen identifying its type. Additional features provided by the app include characteristics of the trees and the regions in the United States most conducive to their growth. (Photo by Rudy Brandl of Fanwood)
