101+10 New Science Games: Learning science with fun

By Ivar Utial

Supplementary science books not only interest and excite young students,but also stimulate their interest in the subject. This exciting book shows you how to have fun with 101 Science Games. There is little doubt that science experiments can be quite interesting and useful in discovering mysteries of nature.In fact,it is the science that has led man from the lantern and the bullock-cart age to Electronics and Supersonic Jet age. The book is fully illustrated with step-by-step instructions to give you hands-on experience of making simple scientific equipments like:

*Telescope

*Barometer

*Hectometer

*Model Electric Motor

*Electroscope

*Periscope

*Steam Turbine

This project-work will acquaint you practically with the basic principles of specific applications. Now, you too can prepare for your next science fair.

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
