Third-graders win national science prize

Four third-graders from North Reading’s L.D. Batchelder School learned on Tuesday that they placed first in the K-3 category of the world’s largest science and technology competition, the Toshiba/National Science Teachers Association ExploraVision contest.

The 9-year-old students — Harley Duffley, John Jennings IV, Annika Howe, and Abby E. Wall — impressed judges with their SIGHT system project, a futuristic tool that features holographic imaging and a map to help firefighters strategize their life-saving methods and prevent property damage. SIGHT — which stands for Safety, Interactive, Guided, Holographic, Technology — was inspired by Howe’s father, who is a police officer, and the students wanted to help those who work in public service.
