Question

essay on wonders of science for class 10th

Answer 1

In the past, there were only eight wonders in the world. But today there are hundreds of wonders. Every invention of science has changed this world into a land of wonders. These wonders are not only beautiful but also useful.

How wonderful our aeroplane is! We were not born with wings. But we always wished to fly like birds. Science has given us what God has not. Today we can fly to any corner of the world. Rivers and mountains cannot stand in the way. How cheap and how easy it is to travel now! Today we can travel even to the moon. Our jets and rockets will carry us there. What a change from bullock cart to aeroplane!

Our radio is even more wonderful. What a useful servant it is! It brings music and news from far and wide. You hear great men and enjoy music in your own room. This wide world now lies in your small pocket. How small your transistor is, but how wonderful its service is! Now you can hold the whole world between your fingers. But our television is more wonderful still. You not only hear but also see the whole world with your own eyes. You see people talk or sing or dance. Thus science has conquered both time and space.

Electricity is not less wonderful.Electricity lights our homes and streets. It gives us fire, too. It moves our trains and trams. It runs our mills and factories. You switch on a button and get everything. What a wonder! Even a magician cannot do what electricity does.

So, today we cannot live without science. Science gives us a new life. How easy now is the work of doctors and surgeons! A surgeon does what even a magician cannot. How wonderful is the work of X’-ray! Is this ray less wonderful than the rays of the sun?

But science has produced some fearful things, too. Atom bombs and hydrogen bombs are great wonders, no doubt, but they are also great dangers for man.

Answer 2

Modern civilization is the gift of modern science. Today we are living in an age of science. Day and night we make use of innumerable discoveries and invention of science.

Electricity is the great power behind many scientific inventions. The electric lam lights up our houses. Radio, television, telegraph, telephone, cinema, tape-recorder, photo-copier, VCR, computers and most of the mills and factories are run by electricity. There are also electric trains, printing press, cookers, irons, sewing machines etc. run by electricity.

Science has conquered space and time. We can go from one place to another place in a very short time by train steamer, plane or rocket. We have reached the moon. We can now send messages to a great distance in a second. We can talk to anybody in any part of the world by mobile phone. Radio brings songs, music, news, discussion etc. Television brings pictures also even in color. By FAX, any writing or picture can be sent over great distance very easily. Internet is yet another wonder of modern science.

Spinning of yarn, weaving of cloth and sewing of cloths can be done at a great speed. Food processing, house-building, constructing roads and bridge can be done very quickly. Millions of pages can be printed or reproduced in a short time. A calculator can solve complicated sum in no time.

Science has discovered the causes of most of the diseases and their remedies. A deadly disease like TB has been conquered. Cholera has also been brought under control. Small pox has been eliminated. The X-ray and the antibiotic have been very helpful to man. Cornea transplant, by-pass surgery etc. are marvels of medical science.

Science has increased food production greatly. If we can apply the scientific methods properly, there will be no hunger in the world. Tractors, power-pumps, fertilizer, high-yielding varieties of crops and irrigation techniques have revolutionized agriculture.

But science is not an unmixed blessing. Science has also invented guns, bombs and missiles, battleships and war planes, chemical weapons and nuclear war heads. To speak the truth science has both blessing and curse.
