Organized chaos spells creativity at Brooklyn school science event

A Brooklyn elementary school was transformed into a high-tech laboratory during a Cornell-led science discovery day Oct. 4.

About 300 schoolchildren jammed all corners of Public School 21 as part of the 10th annual 4-H National Youth Science Day that reached an estimated 100,000 schoolchildren in 50 states. Last fall, Cornell led the national “drone discovery” theme.

This year’s interactive learning challenge, “Incredible Wearables,” was developed by the University of Nebraska-Lincoln. Youths engineered and built electronic armbands that measured their fitness while exercising.

Fellow youth scientists then monitored and measured heartbeats and number of steps or jumps taken.
