UJJAIN: More than 150 models were presented by school and college students at the three-day science fair organized by the Madhya Pradeshscience and technology council in Ujjain which concluded here on Tuesday.
The models by the students displayed their scientific skills which became a treat to the eye. In a model, Mayuri Sunere and her group presented an unmanned railway crossing that could be managed with sensors and an automatic opening. Talking to TOI, she said there are many unmanned railway crossings with low or negligible traffic. "The risk of crossing over the unmanned level crossings could be avoided if the gate automatically closes on the arrival of a train based on the technology of judging the distance," she said.
Similarly, students of School of Excellence Madhavnagar presented a model for early warning of earth quake and claimed that if hollow pipes are erected below the ground at quake prone places, gases like methane which emanate before quakes would come up through the pipes and raise an alarm.
Intriguing models of purifying polluted water through natural process, multi level car parking, agriculture robot and others were also presented.
