Science models to resolve problems

Improving communication to battling disease, enhancing safety on railway tracks to monitoring attendance in schools — myriad problems and their creative solutions were all on display at a state-level science fair that got underway in Ranchi on Monday.

Budding scientists — all 125 of them — from 21 districts were in attendance as the two-day 40th Jawaharlal Nehru Rashtriya Bal Vigyan evam Paryavaran Pradarshini organised by the directorate of secondary education kicked off at the Amar Shaheed Thakur Vishwanath Shahdeo Zilla School. The chief guest on the occasion was secondary education director Mamata, while the guest of honour was district education officer (DEO) Maheep Kumar Singh. The theme of the fair was Science and Society.

The students based their exhibits on topics like industry, natural resources and its protection, transportation and communication, information and community health and mathematics. Niranjan Kumar, a Class IX student of Ganesh Lal Agarwal School in Palamau worked on the topic information and technology.

“Terror threat on our railway network is very real. With the help of my exhibit, I have shown how thick and unbreakable rubber chords connected to the railway track can be used to alert a station master in case terrorists try to blow up tracks,” he explained.

If Kumar’s idea was an eye-opener, equally impressive was KV Girls High School, Ranch’s Urvashi Kumar’s take on groundwater contamination.

To help rural folks who are at the risk of lung cancer, skin cancer and kidney problems due to groundwater contamination with arsenic and fluoride, Urvashi not only chalked out a solution but also created an avenue to spread awareness about the hazards of arsenic poisoning. Her model showed how villagers could adopt rainwater harvesting, use filters, adopt deep-boring system, and use earthen pitchers to keep arsenic poisoning at bay. Consuming iron-rich foods was also a suggestion.

The young scientists were of the opinion that day-to-day problems could be sorted out at minimum cost. Sabia Khanoon, a ninth grader of Ursuline Government Girls High school showed with her exhibit how the government could depute more doctors in rural pockets to bring down healthcare costs of rural folks.

Likewise Kiran Senapati, a ninth grader of St Anne’s Girls High School, Ranchi propagated the use of biometric fingerprint scanners in schools to monitor attendance.

While vividly explaining the use of mathematics in our daily life, Phulan Kumari, a ninth grader of SN High School, Ramgarh showed how objects of everyday use could be taken as tools to teach a child the basics of mathematics.

The exhibition will conclude with the prize distribution ceremony on Tuesday.
