Removing Cancer causing Chromium from water- Award winning Sri Lankan School Science Project at USA Science Fair

Two students of the grade 13 AL class in the science stream of S DE S Jayasinghe Central College, Dehiwala, Ravindu Sankalpa Perera and Shehan Kavishka have shown their talents and won the grand award in 4th place in the earth and environmental science category at Intel International Science and Engineering Fair (INTELISEF), 2017 held at Los Angeles, California, this year with their project based on removing carcinogenic chromium ions from our natural water sources. This international competition hosted 1,778 contestants from 78 countries. Sri Lankan students have been participating in this competition over the past 10 years, but this year is the first time that such a victory has been achieved by our country. In addition to the grand award, Shehan and Sankalpa were also awarded the ‘Mawhiba’s special award for their experiment.

Sankalpa and Shehan hope to sit for the G.C.E. AL examination this August.  They have been able to manage time between studies and their experiments due to encouragement they got from their school teachers. Dr. Meththika Vithanage, Senior research fellow of the National Institute of Fundamental Studies, Kandy has supervise them throughout the competition as the principle supervisor and has provided students with the lab facilities, accommodation. Students would not have been able to achieve all of this if not for her help and guidance.
