In the State Level Science Exhibition 2019 which was held at Govt. Higher Secondary School, Itanagar, in that there were 34 models from different Districts of Arunachal Pradesh on the given main theme “Sustainable Development”. Under this main theme there were six sub themes. Our sub theme was “Resource Management”. From our School Km. Santoshi Dhanaji Bhendavadekar and Km. Trishna Sharma of Class XI Science participated Papum Pare District to the State, and in a very tight competition among all 34 models, VKV Itanagar grabbed the First Position, also achieved the First Prize in the best Sub theme “Resource Management”, and First & Second winner will represent the State into the National Level Science Exhibition competition which will be held in the month of January 2020 in Kolkata.

Our model was mainly highlighted disposing the plastic and converting it into the manure, working model of solar car with vacuum cleaner and also had a working model of piezoelectric transducer, which was guided by Sri Sumant Kumar.

The Piezoelectric transducer is an electroacoustic transducer used for conversion of pressure or mechanical stress into an alternating electrical force. The piezo transducer converts physical quantity into an electrical voltage which is easily measured by analogue and digital meter. This can be implemented in the footpaths, parks; spot courts and the area have more physical movement.

Multipurpose solar car is an advance version of solar car which is also works as a road cleaner.
