Students from Calcutta and the Sunderbans displayed their innovative skills at the Science, Technology, Engineering and Math (STEM) Talent Search held at EZCC last month. Artificial clouds, solar caps, windmills, an eco-friendly village and baul songs greeted visitors at the grounds. Besides city students, 45 children from the Sunderbans also participated in the talent hunt. Students of Janapriya Vidyalaya at Janaypriya Nagar in the Sunderbans exhibited a model depicting the irrigation technique of the area.
“The soil in the Sunderbans is salty and that affects the vegetation there. Growing taro is a natural remedy. It absorbs the salt from the water,” said Anil Kumar Chaulia, a teacher of the school. Students of St. Augustine’s Day School in Calcutta created an artificial cloud by condensing ethyl alcohol. Fireworks, sulphuric acid, ethanol and potassium permanganate helped create the lightening effect.
Students of South City International School were also appreciated for their battery-operated car, quickly programmed robot and solar cap.
“My cap cools you in the hot sun,” said Aryan Agarwal, a Class VI student of the school. He placed his cap near a glowing bulb and a fan fitted inside it instantly switched on. “I have made the solar cap with the use of waste products like parts of my brother’s broken toys, springs of used pens, and an old cap,” Aryan said.
Satyajit Bhattacharya, the founder, president and CEO of Association of Science and Society, the organisers of the programme, also announced a 12-panel plan for socio-economic,cultural and scientific developmental for West Bengal.
