A three-day regional science exhibition of CBSE concluded on Sunday 21st January 2018. The event was organised to promote practical learning of science and technology among school students.
A total number of 36 exhibits were put up by the students of 23 CBSE schools across the region. The models and projects based on seven themes-waste management and water body conservation, digital and technological solutions, resource management and food security, mathematical modelling, transport and communication, health and well-being and others were judged by the eminent teachers and scientific experts headed by Associate Professor Dr U.S. Rana from DAV College, and followed by Scientists E from DRDO and IRDE Dehradun. Regional officer, CBSE, Shekhar Candra and Gopal Dutt also visited the site and inspected the innovative models presented by the school students.
Manava bharati india international school also participated in this science event. Our students Ashmit Rana and Soubhagya Daspattanayak of Class VIII B presented a model titled “Sensor based vacuum garbage picker for Public and Private vehicles” under digital and technological solutions theme of the exhibition. When asked about idea behind this project, the students replied ” They observed that in general it is difficult to clean the main city roads and highways because of continuous traffic and talking about a tourist/picnic spot parking is mostly dirty as visitors and their driver both eat and just throw the garbage in there in the parking space. Therefore, we thought of modified public transport (bus) etc. such that they work as garbage picker while doing their transportation duties. The modification consists of creating a vacuum chamber / garbage collection chamber and attachment of IR sensor to the front lower part of the vehicle. The IR sensor detects the garbage and as soon as it is detected a signal is sent to the vacuum port which initiates the vacuum chamber and garbage is sucked in from the road. Further they added that most of the project prototyping was done and developed at the Atal tinkering lab of the Manava Bharati School.
The use of IR sensor confirms that vacuum activates only when there is a garbage, this will reduce unnecessary usage of energy.” In future work the students said that instead of IR sensor two different proximity sensors can be used to segregate the metallic and non metallic wastes right at the sensing stage and collect them in two different chambers, so we have segregated waste that can be later recycled or dump as required. The judges and other participants really liked the idea. The judges and principal of The Asian school appreciated the project and said that this is really needed in our country. They also suggested to improve the model by implementing the idea in real size model and get more details on the implementation and service cost for real time case. A total number of 11 models were selected for the next round, that is, the national level after two rounds of judgements.
