The ‘ignited minds’ demonstrated their prowess in science by displaying novel exhibits at the district-level science exhibition conducted as part of INSPIRE Award 2012 in Tirupati recently.
The students dwelt on topics ranging from water conservation to environment protection, food security to renewable energy, but the exhibit by Alladi Vikram Chandra stood apart as it was on ‘Working of hydraulic machines’, a topic considered as knotty and incomprehensible for a seventh standard student.
The exhibit demonstrated the principle behind the working of hydraulic machines using three models. The first one was based on the principle that force that is applied at one point is transmitted to another using a confined fluid. The second model of a proclainer is used to lift a bucket and shift it to another place.
“I used the engineering set for the framework of this model and integrated it with three sets of syringes and intravenous fluid tubing, to facilitate horizontal and vertical motions, besides holding and releasing weights,” Vikram Chandra, a student of BVB Sri Venkateswara Vidyalaya, explained. The third model of a hydraulic jack, based on simple Pascal’s law, employed two 5ml syringes, a 50ml syringe and two cycle ball-bearings, which effectively lifted weights up to 1.5 kg. Going by the concept ‘wealth from waste’, the exhibit was made by products either discarded or disposed of.
The exhibit has been selected for participation at the State-level exhibition to be held at Hyderabad.
