Health, green lessons in science models

Ranchi, July 27: As many as 200 models, illustrating a host of environmental and health issues, were showcased at a daylong science exhibition at DAV Public School, Bariatu, on Saturday. About 800 students from Classes V-XII took part in the event.

While some highlighted environmental issues like global warming, terrace farming and climate change, others depicted ailments like kidney problems and cirrhosis.

Venkatesh, an eleventh grader of the CBSE-affiliated cradle, worked on a rare disease — ulcerative colitis — that is gradually becoming common in India. “Five years back, people were unaware of this disease but recently, there has been a rise in the number of cases. Its symptoms are abdominal pain and diarrhoea and it can be treated by medications and surgery,” explained Venkatesh.

Two more Class XI students Pushpanjali Singh and Alisha had prepared models on liver, in its healthy and weak stages. “We have illustrated cirrhosis, which is caused by high consumption of alcohol,” Alisha said.

Subhashree Rout and Shweta Bharti came up with a model on blood cancer, which has gained ground in India in recent years.

A four-member team, comprising Soumita Das, Kriti Ojha, Kaushik Yashraj and Nikhil Kumar, showed how flash floods, like those that ravaged Uttarakhand, could be prevented. The students put in place a water-level indicator and flood water alarm system to illustrate their ideas.

“In both urban and rural areas, we can control flood by building small dams and install a indicator, which will alert people in nearby areas if water level rises beyond a safe point,” Das said.

Shivani Aditi and Zeenat exhibited how water pollution can be curbed by means of a sewerage treatment plant. “With the help of a treatment plant, we can purify water and minimise pollution. This water can be then recycled and used for irrigation purposes,” they said.

A teacher of Surendranath Centenary School Sanjay Sahay, who was one of the judges, said: “All came up with innovative ideas.”
