AURANGABAD: The 44th district-level science exhibition underway at Shri Sai Institute of Technology Polytechnic, Chikalthana MIDC is slowly turning into a pool of new ideas as school students are coming up with innovative concepts on issues like waste management and traffic snarls.The event is being organised by Zilla Parishad, Aurangabad , and National Council of Educational Research and Training (NCERT) from January 17 to 19. This year, the theme of the exhibition is ‘scientific answers to life problems’. After excelling at the taluka-level, students from different schools are now gearing up for the district-level competition.The exhibition is showcasing simple yet effective models which can be implemented to address issues related to drought, energy sources, solid waste management, health and agriculture.Students of Kailash Laxmanrao Patil Vidyalaya from Shivna Village near Ajanta Caves assembled a water purification system using pebbles, coal and soil seeking the help of Youtube videos.In another model, Class IX student Nutan Shirbhaiyye from Khuldabad’s Sadguru Janesh Madhyamik Vidyalaya has found an answer to growing nutritious feed for cattle in a short time using minimum resources. “Through a method called hydroponic, I have grown 20kg maize crop for cattle feed without soil in 6 days using corn,” said Nutan.Students of Ellora’s Gurudev Samantbhadra Vidyamandir used corn starch, glycerine, potato starch, orange peel powder and vinegar to produce bioplastic, an eco-friendly alternative to plastic.In order to avoid accidents on hilly roads, a team from Ganori’s Zilla Parishad school suggested that rolling pillars made up of steel and foam be used as road railings. “If the vehicle hits the railing, instead of falling into the gorge, the vehicles will be redirected on the roads due to rolling pillars,” said the students.
