A city school will represent the state at the 97th Indian Science Congress in Thiruvananthapuram.

The five-day event starts on Sunday and will be attended by former President A.P.J. Abdul Kalam and former chairman of Indian Space Research Organisation G. Madhavan Nair.

Students of Modern English School, Chembur will present their project at the children’s science congress along with 100 other projects selected by state-level congresses across the country.

Around 3,500 students are scheduled to take part in the various events at the congress.

“This is not a competition but an effort to encourage an interest in science in children and give them an opportunity to interact with eminent scientists,” said Jayaji Nair, convener for publicity and coordination.

The group of five students — Parimalasree C, Gayatri Menon, Nivedha B, Shailaja S and Siddesh S — derived a way of purifying contaminated water through a process called phytoremediation.

They tested and recorded the impact that duckweed had on water samples contaminated with concentrations of copper, lead and zinc. They observed that duckweed significantly lowered the concentration of these harmful metals present in the water.

“When polluted water from industries is released into the open, it affects aquatic life and could enter our bodies through the food chain,” said group leader Parimalasree.

“This is a way of making water safe.”
