A 15-year old girl named Srishti Asthana, studying in class XI in Millenium School in Mohali, has been secured her place among the top 15 finalists of the Google Science Fair, 2013 this year. Started in 2011, the Google Science Fair is an online competition which is open to students in the age groups of 13-18 to widen science projects and share their innovative findings.
Srishti Asthana along with other entrants will now be flown to Google’s Mountain View headquarters in the US on September 23 to present her project for the final round, which will be judged by an international panel of esteemed scientists. The winner of the contest will get a grand prize which includes ten-day trip to the Galapagos Islands, $50,000 in scholarships, and lot more. Her project is related to green method for treating industry’s waste water laced with detergents causing water pollution.
Speaking to an English daily, Srishti said:
As a part of a field trip, I went to Ludhiana last year and was taken aback to see how the dyes from the textile industries got drained out in the water bodies, thus polluting it. On querying from an owner on how they treated the water before draining out, he counter questioned me on whether do we treat the detergent water before draining that out. The question triggered an idea in me of doing the same.
I created a method where the solar light and nano particles of zinc oxide are used to treat detergent water. It is purely a green technique and environment-friendly.
