Publisher’s Note
In line with a number of books in the Popular Science category, such as the bestsellers, 71 Science Experiments, both in English and Hindi, Children Science Library, etc., the V&S Publishers now present to you with another interesting, exciting and fully revised Science book for children called the 101+10 New Science Games along with an interactive CD. The book is a collection of 101+10 amazing and fun-filled Science Experiments, particularly for the school-going kids to carry out all by themselves with the help and guidance of their parents or elders at home or under the guidance of their teachers at school.
Science, as we are well aware of, forms the basis of human life. So, beginning right from the Discovery of Fire by the early man to the Invention of Satellites and Missiles, Science and Technology have throughout influenced and transformed our lives down the ages.
Although, it is doubtless that Science has changed our lifestyle completely, yet children, especially at the school level, find it a nightmare to understand and learn the scientific laws, theories, inventions and discoveries. Maths and Science are generally considered the toughest and the most important subjects by the school students, which they are indeed! A practical demonstration through experiment is a must in order to understand or learn any scientific law or theory. Therefore, this book, 101+10 New Science Games will be of immense help to our young readers, who otherwise find it difficult and boring to go through their routine science books prescribed in the syllabus.
They can perform simple experiments of air pressure, volume, density, temperature, sound, magnetism, etc., given in the book and understand as well as learn these phenomena easily by the fun way, i.e., they can learn the laws and theories involved as well as enjoy the thrill of conducting these experiments by themselves under the guidance of their parents, elders, or teachers.
Thus, this book, in its altogether new avatar with an Interactive Free CD can help the children develop a keen interest and inclination towards Science, which will certainly make the subject easier and more lively. Hope it serves its purpose effectively.
Between You and Me
There is little doubt that science can be quite an interesting and exciting subject. In fact, in the modern world, it has become so much a part of our lives that we can not even imagine our existence without it. Can you imagine your life without the railways, electric light, telephone, newspapers and so many other gifts of science ?
The first step towards the advance of the great human civilization was the time when man first rubbed the stones and produced fire. Similarly, it was the invention of the wheel that set the ball rolling to usher in the technological revolution. It’s the same spirit of science that is still driving ahead the man towards new achievements every day. It’s again science that has led man from the lantern and cart age to that of electronics and supersonic Jets. Had it not been so we would have still been living in caves wearing animal skins and sleeping on tree branches.

Break Thread at Will
Articles Required: One thick book, a long piece of fine thread.
Divide the thread into two parts. Take one part, and hang the book from it and tie the other part to the underside of the book, as shown in the figure here.
Now you ask a friend if he can break the thread from above or below the book as per wish just by pulling the lowermost end only, he wouldn’t know what to say. But when you assure him that it is possible and the thread can be broken from either side at one’s wish, he would be left wonderstruck.
To do this, there is just a simple hand trick. If you have to break from the upper part first pull the thread downwards and gradually increase the pressure. But if it’s to be broken from the lower part you just have to give it a sharp tug and only a small piece of thread will remain in your hand. The inertia of the book prevents the force produced by jerk from reaching the top and as a result, the thread breaks from below the book only.

Join glasses with Air!
Articles Required: Two glasses, rubber ring, paper and matchstick.
Air acts as quickfix? How funny! Perhaps there is some misunderstanding. Well, here you can join, not broken pots as with quickfix but two glasses with air. And if you want to separate them, you can do that too at your will !
For this experiment, you require a right-sized rubber ring that would fit weli on the glass. First, take one glass and drop a lighted piece of paper into it. Before the paper burns out, invert the other glass on top and put the rubber ring in between. By the time the paper has burnt out, the glasses would be joined together. Now if you pick up the top one only, the bottom glass would also come up with it. Yes, they’ve got joined—simply with air I
Do you know how? The oxygen present inside the glasses is used up in the burning of paper-leading to decrease in air pressure. Outside, the air pressure is greater and acts on the glasses forcing them to stay together.

Where has so much of salt gone ?
Articles Required: A glass of water, a salt-celler full of salt, a fine sieve.
Take the glass and fill it with water upto the brim. Now if you put a heaped tablespoon of salt in it, do you know what would happen? No, probably you can’t answer until you try it yourself. You’ll be amazed to see that all the salt gets dissolved without spilling even a drop of water.
Hold the sieve above the glass and start sifting salt into it. Make sure that the salt is absolutely dry. As more and more salt goes into the glass, the solution’s volume would appear increasing. But it will happen very slowly. In fact, the total volume of the salt solution would always be much lesser than the combined volume of the salt and water separately. Do you know where the extra salt goes?
Like other compounds and elements, water is also made up of a certain arrangement of molecules. These molecules freely move about leaving sufficient space between them. When the salt is dropped into water, the sodium and chlorine atoms fill these spaces and prevent the volume of water from increasing and the water doesn’t spill out of the glass.

Which side the stick would fall ?
Articles Required: A 70-80 cm. long stick.
Perhaps to begin with you might not enjoy this game, but don’t worry, as it’s one of the most interesting games in the entire book. So, let us begin. O.K.? Close your fists in such a way that your forefingers extend forward. Now, as shown in the figure here, place the stick on these fingers—with one end of the stick extending a little more on one side than on the other. While demonstrating to the friends ask them if the fingers are slowly brought together on which side the stick would fall. Everyone would say the same thing i.e. it would fall on the side from which a bigger part of the stick protrudes. Not just them, aren’t you also thinking on the same lines? Isn’t it?
But when you start bringing the hands closer what happens is just the opposite of what you had thought. Do we tell you? In fact the stick just doesn’t fall. It refuses to fall whether you bring the fingers closer or take them away.
Well, now get to know the reason for this also. In fact the bigger end of the. stick exerts greater pressure on the finger as compared to the shorter one. And the greater pressure produces greater friction. So while attempting to bring the hands together the stick always slides from the-shorter-end’s side where friction is less. That’s the reason it continues to keep its balance and refuses to fall.

Sparrow—in or out ?
Articles Required: A white cardboard piece, thin white string and a sketch pen.
Take the cardboard piece and the with the help of sketch-pen draw the pretty figure of a sparrow on one side, and of a cage on the reverse. The cage should be big enough to accommodate^ the bird. Now just make two holes at equal distances on the two sides of the cardboard piece. Slip the string through them and be off with worries, as your game is ready.
Do you know on what principle this works? You’ll be surprised to learn that the motion pictures run on the same principle. The principle is that whatever we see leaves its impact on our eyes for around l/16th of a second. The scientists took advantage of this fact and gifted the mankind with this exciting invention.
And here too because of this property of the eye, you would see the sparrow caught in a cage. Now as you twirl the string rapidly, the cardboard piece rotates and the images of sparrow and cage quickly succeed each other—creating an impression that there is only one picture, and that of the sparrow inside the cage.

Cold water—heavy, Hot —light
Articles Required: Two empty bottles, hot and cold water, a thin sheet of cardboard, blue or red ink.
Put blue or red ink in a bottle and fill it with hot water upto the brim. Take the second bottle and pour cold water in it. Now keep a cardboard piece on its mouth, press it with your fingers and invert the bottle on top of the olher one.
Once the mouths of the two bottles come in alignment gently pull out the cardboard piece. The water in the two bottles will come into contact with each other and soon you’ll notice that the coloured water from the bottom starts rising upwards, and the clean water starts flowing down.
Do you know why it happens like this? This just goes to prove that the hot water is lighter in comparison to cold water. And that is because its specific gravity is less than that of the cold water.
