‘I am the master of my failure… If I never fail how will I ever learn -C. V. Raman

Innovation in Science Pursuit for Inspired Research' (INSPIRE) scheme is one of the flagship programmes of Department of Science & Technology (DST), Government of India. The INSPIRE Awards - MANAK (Million Minds Augmenting National Aspirations and Knowledge), being executed by DST with National Innovation Foundation – India (NIF), an autonomous body of DST, aims to motivate students in the age group of 10-15 years and studying in classes 6 to 10. In the year 2020-21, 32 projects out of 835 projects of KVS state were selected under Jammu Region for DLEPC. These students were honoured withRs10,000/- for further upgradation of projects for next level. Out of 835 projects of KVS State, only 75 projects were shortlisted for SLEPC conducted in the month of Feb, 2022. Out of 75 selected projects of KVS State 2 projects are selected from Jammu Region for State Level Exhibition and Project Competition (SLEPC). Miss Vanshika Lochan, a student of class IX from Kendriya Vidyalaya Bantalab and Miss Kashif Sidiqi a student of Class X Kendriya Vidyalaya, Uri. Miss Vanshika Lochan had presented project titled “LANDSLIDE EARLY WARNING SYSTEM “Miss Kashif Sidiqi had presented project titled “COLLECTION OF FLOATING GARBAGE THROUGH PONTOON BRIDGE”.

Inspire Achievers Figure 1: LANDSLIDE EARLY WARNING SYSTEM Miss Vanshika Lochan, a student of class IX from Kendriya Vidyalaya Bantalab and had presented project titled “LANDSLIDE EARLY WARNING SYSTEM”This whole project is based on the principle of moisture under the soil. If the moisture is high, then there are more chances of landslide. The circuit diagram of early landslide warning system, includes Arduino which will act like commander for the whole circuit diagram, a buzzer which will produce sound as alarm, a LED light which will blink to warn the drivers driving on the road, and humidity sensor which will detect the moisture under the soil. 3 circuit diagrams have connected like this to make a series combination and produce a big alarm. This is a very good innovation for people who are living in hilly areas.

Figure 2: collection of floating garbage through pontoon bridge Miss Kashif Sidiqi, a student of Class X Kendriya Vidyalaya Uri had presented project titled “COLLECTION OF FLOATING GARBAGE THROUGH PONTOON BRIDGE”. We need a pontoon bridge with a wire mesh attached it vertically downwards. The wire mesh should be approximately 1-1.5m long. With above mentioned structure we can collect all the floating garbage in the rivers which is not very easy to be removed. The rivers have lots of garbage and plastic drained into them making the water contaminated. To make the purification process easier this structure can help us through. It is environment friendly without any additional investment plus it can be a good source of employment generator. With respect to Indian geography our main rivers like Ganga and Brahmaputra already have pontoon bridges over them, we can use small scaled pontoon bridges on smaller rivers, that make up the bigger rivers, and clean the garbage that is being transferred to the bigger rivers. It is a suitable idea for the cleaning of rivers in India and other countries. Rushil Sharma, Aditya Mahajan, Sparsh Anshika, KV No. 1 Udhampur KV No. 1 Udhampur KV No. 1 Udhampur KV Bantalab

`DO OUR DNA HAVE A PASSWORD? We all need a password for a new device or for many other services. Similarly we also got some tiniest, most complicated set of instructions which play an important role in determining physical traits — how we look —and lots of other stuff about us. These Segments of DNA that contain instructions for building the molecules that make our body work and telling it how to operate is called Gene’s. Genes carry the information and are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes. Genome It is the complete set of genes or genetic material present in a cell or organism. All living things are evolved from a common ancestor. Therefore, humans, animals and other organisms- all have DNA; so do trees, mushrooms and bacteria. Without DNA, life would be impossible. AKANKSHA SHARMA TGT SCIENCE KV KISHTWAR

DNA I am the one with two strands, Who determines an individual’s brand. I give identity, multiplication and replication, Each and every character is in my narration. Can you imagine, how awesome I am, As I am the solution of most of the scam. No one can beat my storage system, Which makes me responsible for your inheritance custom.

Cyber Crime In present time, being posed by a variety of cyber threats, difficulties are arising more and more, in each field associated with technology. Criminals are targeting the public as well as private sector networks that lead to harmful results. Cyber-crime takes different forms as: Hacking: The act of gaining unauthorized access to data in a computer or computer network. Malware: A malicious software, refers to any code designed to interfere with a computer’s normally functioning. Identity Theft: Unlawfully obtaining other individual’s personal information and use it & thus committing a theft or a fraud. Social Engineering: psychological manipulation of people into performing actions or divulging confidential information. Software Privacy: unauthorized reproduction, distribution and use of software. Cyber Crime in India India is a developing country where internet is too growing very fast in every state with regular increase in cybercrime. Cyber-Crime in India is also notable where lack of awareness of use of technology and recoupment in cyber laws is one of the factors. India reported 2,08,456 Incidents in 2018, 3,94,499 incidents in 2019, 11,58,208 incidents in 2020, 14,02,809 incidents in 2021 and 2,12,485 incidents in first two months of 2022. Preparing Students To Fight Cyber crime Cyber-crimes mutate constantly in our society in present time. To prepare our students to fight cyber-crime, we need to implement dynamic learning techniques to provide a strong foundation in cyber security concepts and leadership skills, as well as multiple concentrations that allow them to develop advanced expertise in key areas of the field.

Micro plastics: A hidden threat Microplastics pose a global problem. However, only 43% of the countries are actively involved in studies on microplastics. Microplastics are plastic particles less than 5mm in diameter. They contribute to over 80% of the ocean debris. The plastic materials discarded by humans traverse through land and are passed to the oceans by wind or rivers. These plastic materials are broken down to smaller particles by exposure to sunlight or wave action. These smaller plastic particles are called microplastics. Marine organisms such as fish, crabs and prawns consume these microplastics by misidentification as food. Humans consume this seafood which leads to several health complications. Thus plastic materials discarded by one man ends up on the plate of another man through seafood and sea salt. On a wider scale, the presence of microplastics particles in the air has the potential to influence the climate by accelerating the melting of snow and ice. Microplastics have been even noted in table salt collected from saltpans of Tamil Nadu and in processed salts purchased from supermarkets. The global problem of plastics will only be solved if all countries and decision- making policies decide to monitor microplastics along with their respective coasts and also implement orders to use only biodegradable plastics. Awareness must be created among the common people regarding impact of microplastics. The complete ban on the use of ‘single-use plastic’ from July 1 by the Central Government is a welcome step in this direction but numerous mutual efforts are required in this direction.

Role of Science Teacher in Society We live in a knowledge society. Knowledge – in addition to mineral resources, capital and physical activity – is an increasingly important resource. It contributes to the functioning of democracies and innovation and helps countries to be competitive on a global scale. But science which contributes significantly to knowledge production, is confronted with new challenges. The role of science in an increasingly fragmented and digital society, as well as its significance for politics and civil society, will be redefined. Science can never offer a universal truth or an objective representation of the world. It can, however, offer methodologically verifiable interpretations and can question certainties and trigger reflections. Science has an important social role and at the same time bears great responsibility, precisely, when the situation is not clear. Science thus has an important social role to play. Through science teaching, there will be interaction between science and society. And this will ensure that knowledge is exchanged, tested and reflected in society. In this situation, it is the responsibility of science teacher to make our classroom and our teaching welcoming for all students, regardless of their social identity, gender-identity, cultural background. Kendriya Vidyalayas are constantly chasing the challenges of society through various activities, like: NCSC: It kindles curiosity of the children, provide the opportunity to unfold their creativeness and stretch their imagination. INSPIRE AWARD: The objective of the scheme is to target one million original ideas/innovations rooted in science and societal applications to foster a culture of creativity and innovative thinking among school children. With the help and kind motivation of our Honb’le Deputy Commissioner sir, Dr. D. Manjunath and Worthy Principal sir DR. R. K Srivastava, Kendriya Vidyalaya Sunderbani has achieved many achievements in these activities during last two years. Vishesh Gupta- Awarded with Rs. 10000/- for INSPIRE AWARD in 2020-21. Esha Sharma- Awarded with Rs. 10000/- for INSPIRE AWARD in 2021-22. Shaurya Hirdekar- Awarded with Rs. 10000/- for INSPIRE AWARD in 2021-22. Deepak Gupta- Awarded with Rs. 10000/- for INSPIRE AWARD in 2021-22. Khushi Sharma- Awarded with Gold Medal as Rank-1 in KAMP. Being science teacher, I request all teachers to motivate, students to use their knowledge for making our society innovative with novel concepts. Regards Pgt physics Kv sunderbani
