For Lalita, 13, a DPS student from Odisha, Google Science Fair 2015 award for her project utilizing corn cobs was to filter polluted water came as an apt appreciation of her extrapolation of nature’s observation.

She won the Community Impact Award for her project, which makes a practical difference by addressing environmental, health and resources challenges.

Lalita Prasida Sripada Srisai, a Class 9 student at Delhi Public School, Damanjodi, was the only Indian to win the prize though five others are of Indian origin. Three of them are from the US and one each from the United Kingdom and Singapore.
