Imagine being a part of a mission that will script the history of a nation. What if you were a part of a team of top scientists and researchers, secretly executing this mission. Doesnt this sound like the storyline of a spy thriller? Wait! This is the true story of Indias Operation Shakti or Pokhran – II, which was launched on May 11, 1998.
The countrys top notch scientists and researchers put in their heart and soul for the success of this ambitious project. Operation Shakti was the brainchild of former president late Dr APJ Abdul Kalam and his team of prolific scientists, including Dr Rajagopala Chidambaram, K Santhanam, Dr Anil Kakodkar, M S Ramakumar, S K Sikka, Dr D D Sood, G Govindrajan, S K Gupta among others.
May 11, 1998, is an important day in the history of science and technology in India, as it marked three remarkable events that put India on the global map, as one of the tech-empowered nations in the world.
|
The three defining events are: Shakti or Pokhran II was an experiment launched to test Indias nuclear power. A series of five nuclear tests were conducted in Pokhran, Rajasthan. These experiments resulted in India becoming the sixth nuclear country in the world. Hansa-3, an aircraft built by the National Aerospace Laboratories (NAL), was successfully test flown in Bangalore. It was the first indigenously built aircraft in the country, making way to become self-sustained in the field of aeronautical sciences. Trishul: A full-range guided flight of Trishul-a missile developed by the Defence Research and Development Organisation (DRDO)-was successfully test fired on this day. It was one of the Navys first anti-sea skimming missile. |
Given these successes in the field of technology, May 11 was declared as the National Technology Day by former Prime Minister late Atal Bihari Vajpayee. He envisioned this day to symbolize the quest for scientific inquiry, technological creativity and translation of that quest in the integration of Science, Society and Industry. The Indian government celebrates this day by awarding innovations by individuals and industries in the field of science and technology every year, since then.
Now that you know the story behind the historic May 11, you may wonder as students, what could you do? Perhaps, celebrate science in everyday life.
This National Technology Day, let the scientist in you bloom! We have two Do It Yourself (DIY) experiments for you. Were sure these experiments will pique your curiosity and teach you a lesson or two in science.
DIY Experiment: Hot and Cold Air Experiment
Grades: 4 8
Materials needed:
How to do it?
Science Behind the Experiment
The plastic bottle contains air in the form of gases. Gases expand when theyre warm. The heat acts as the energy that expands the gases and makes it dense. As a result, the balloon inflates. Similarly, gases contract in cold surroundings. The cool air doesnt have much energy so it contracts the air, making it less dense. Hence, the balloon deflates. Dense gases always float on top of less dense gases. This is how parachutes work. Dense hot air in the parachute balloon makes it float in cooler air.
DIY Experiment: The Sound Wave Experiment
Grade: 9 12
Materials needed:
How to do it?
Science Behind the Experiment
When you hit the spoon with the ruler, it vibrates, creating sound waves. These waves travel up the woolen string all the way to your ears. Here, the woolen sting acts as a conductor (its an object that allows sound to pass through it easily). The wool allows for the continuity of the sound waves, which creates reverberation. Thats why, you continue to hear the sound for a little longer after hitting the spoon.
Let us know in comments about your experience in doing these DIYs. Are you curious to know more about these topics? Watch the videos given below to get a better understanding:
Charu, a feminist and an accidental writer, is yet to master the art of writing about herself. Always curious to learn new stuff, she ends up spending a lot of time unlearning the incorrect lessons. She enjoys all sorts of stories – real, fictional, new, old, hers and would love hearing yours too. Feel free to ping her at storyweavers@byjus.com to share anything that you think is worth sharing.
Arya C is a 4th grader who talks about her transition from the US to India and how BYJU`S has helped her at that. She also loves how BYJU`S has made learning a lot more fun.
Meet Sourabh who has a ton to say about his BYJU`S learning experience. His love for quizzes, games and other fun activities are paying off!
V Shriya is a class eight student who has been using BYJU?S for a year now. She shares her experiences with using the app and how it has helped her in improving her academic performance.
Aanvi from class 9 has been with BYJU`S for just 6 months and hear what she has to say about her learning experience with the app.

I want to be a maths enthusiast like my respected teacher Byju’s Raveendran sir who is a two times CAT TOPPER(? percentiler)
and also a national math Olympiad winner.
Sir if you can see this message then please bless this child rather your student to become successful in reaching his goal a mathematics lover like you.
Thankyou.
