Wishing the whole nation on this occasion in his monthly address through ‘Mann ki Baat’, Prime Minister Narendra
Over 200 young children participated in Sci-Fi Contest. Congratulations to all! This year’s theme invited children to reflect on the topic.

What would you named it? Also how is it going to help the Mankind?” Super Senior Category- “As we all know that we have 5 sense organs in the human body. Imagine you have got a 6th Sense Organ!! What would it be? What will it help us in? Judges were impressed by the
This story is all about Mr. White’s daughter, Sandra White, who was unable to see her father as he died at war when Sandra was just at a young age. Sandra grows up happily even without a father. The story continues when Sandra is at the last day of college and has unknowingly got a special power. The last day of college for the 7 th years didn’t make a difference for the teachers to continue teaching. After the 2 nd hour, in recess, Sandra felt very hot insde. She felt as if some power was pumping up in her
‘To invent is to provide the world a new means to enrich their lives’. This is a quote unheard of by anyone. This is because we prefer to stick to the old quote ‘Necessity is the mother of invention’ and do not try to delve into the hitherto unexplored world of invention-related quotes. Oh well, or maybe this is because I just made this quote and that is why you would have never heard of it. But that’s beside the point. The point is, what will I invent? A quote? Nah. Oh, I know! If I were to invent something,
As a kid when I felt down, my mother used to say “Cheer up kid, after all, you are a B +ve. And I used to think that all the positive people in the world had B+ve blood group and all the pessimists had B –ve. I stuck on to that idea for quite a while before realizing how silly it was. Later in my science classes, I learned the types of the proteins and sugars, inherited from our parents, which determine our blood group. These sugars found (or expressed) on the surface of red blood cells define blood types
Jupiter is the biggest planet in the solar system and because of that its gravitational pull is also very high. Because of its high gravitational force, Jupiter has done many favors to our planet. It helps to keep asteroids away from bombarding to Earth, and protects our planet. One French scientist called Pierre-Simon Laplace found that a comet which was heading towards earth’s surface got into Jupiter’s gravitational field and got expelled from earth’s direction. Like this Jupiter act as a protector of our planet and our lives. Jupiter is the fifth planet, if we consider the distance from Sun.
Sunlight is consisting of multiple wavelengths of light. It includes wavelengths of light which is not visible to us, such as infrared and ultraviolet light, as well as the visible spectrum. Reflection, refraction and dispersion of sunlight inside water droplets in the atmosphere, causes the formation of rainbow which appears as a spectrum of light in the sky. Rainbow appears as a circular arc with various colors and it always seen in the section of sky which is directly opposite the sun. A rainbow is not a physical object and it cannot be approached. It does not exist at one
In the case of normal pregnancy, a sperm cell from male fertilizes an egg cell from a woman. The fertilized egg then gets attached to the wall of the uterus and starts to develop into a baby. But in some cases sperm cells fail to fertilize the egg and the embryo will not be formed and pregnancy will not be happening. In such situations people make use of Assisted Reproductive Technology (ART) to help women become pregnant. In vitro fertilization (IVF) is one of the common ART methods. In the IVF procedure, egg cell is fertilized outside the body and
Have you been to a beach? For swimming in the sea? What is the taste of sea water? It is salty. Why is it salty? There are many chemical substances in the seawater and presence of those chemicals is the reason sea water is salty. Most of those chemicals are carried by rivers which get chemicals from rocks and soil. The major compound in sea water is sodium chloride, which is commonly known as salt. Generally, seawater has about 35 grams of salt per liter of water. Salinity of sea water is measured in parts per thousand (ppt) which tells us about
You might have tried to freeze water in your fridge. But have you ever noticed that hot water freezes faster than cold water? If not, try it yourself. This phenomenon where hot water freezes faster than cold water is called Mpemba effect. The Mpemba effect has been a well known physicist since the time of Aristotle who noticed it more than 2,000 years ago. There were many ideas since then to have been put forward to explain the same. One idea is that warm containers make better thermal contact with a refrigerator and so conducts heat more efficiently, which leads
