Mohali, July 3 (): Srishti Asthana, 15, a Punjabi girl hailing from Mohali is one of the top 15 finalists of the Google Science Fair, 2013. She is a student of science stream studying XI standard in Millenium School.
Srishti has been selected from about 1,000 contestants from 120 countries. In the final round which will be held on September 23, she will present her project to an international panel of scientists at Google’s Mountain View headquarters in the US. The winner of the science fair will be offered a 10-day trip to the Galapagos Islands with the National Geographic Expeditions and $50,000 in scholarship funding.
Srishti will showcase the project, which could be a potential green method for treating waste water mixed with detergents. She got the idea for this project when she was on a school field trip to a textile industry in Ludhiana.
Srishti said when she went to Ludhiana, she was taken aback to see how the dyes from the textile industries got drained out in the water bodies, thus polluting them. On asking an owner about how they treated the water before draining out, he counter-questioned her whether we treat the detergent water before draining that out. The question triggered an idea in her of doing the same.
To solve the problem, Srishti has created a method wherein solar light and nano particles of zinc oxide are used to treat detergent water. It is a green technique and eco-friendly, she added.
The Google Science Fair is an online competition. It was first started in 2011 and is open to students in the age group of 13-18 years to widen science projects and share their findings. Science fair organized this year is the third time Google has organized such a fest. It was quite tough for Google to choose 15 finalists as almost all projects presented to them were very good.
