<p>She was one among the 600 students, who had displayed scientific models as part of the District-level Science Exhibition - ‘Inspire Award 2010-11’ - at St Anne’s School, here on Monday.<br /><br />Chinnushri, a student of St Joseph’s Higher Primary School, K R Nagar, had displayed a model with 12 lemons placed in a circle. A zinc plate on one side and a copper wire on the other side were inserted into the lemon. When the two metals come in contact with Citric <br />Acid inside the lime, low voltage electricity is produced. This was shown using a Light Emitting Diode (LED), which was connected to the circuit.<br /><br />Another participant, Prajwal Prasad, who is a student of Bachegowdanahalli High School in H D Kote Taluk, created a model of an earth moving machine using syringes.<br />With assistance from his teacher Sowmya, Prajwal had created the earth moving machine, which also was able to lift light loads of sand. <br /><br />With pipelines filled with water connecting the arms of earth moving machine, Prajwal had kept six control lines to ensure that the movement of the machine was effective. He said that apart from the arms of the earth moving machine, even the base of the vehicle could be moved to ensure that it could withstand carrying heavier loads. Visitors to the exhibition were spell bound by the unique concept developed by the lad from H D Kote.<br /><br />Scientific models based on natural calamities included Tsunami models, while those on power generation included electricity generation using wind power. <br /><br />Advantages of using solar cookers, an overview of the human anatomy and rockets were also displayed.</p>
