science is a catagory of subjects.
it is combined of four subjects.the four subjects are are mathematics  , chemistry , biology and physics.
these subjects are very important to be studied.
the things or the lessons we study in these subjects is applied by us in our daily life.

we use maths in the shops to calculate price of items .
if we are nor aware of this subject then any one can cheat us .
we can avoid this by calculating the price on our own and this is pssible only if we know how to do addition , multiplicatication  , division , subtraction etc.

next comes the subject biology.
this subject is relation to the study of animals and plants , their structure , their habitat and their physical features.
we study the functions of different organs in animal and plant bodies.
this gives us a huge knowledge about our own bodies as well as other plant and animal bodies.
we can avoid in take of  food which we cannot digest.

the next is chemistry.
chemistry usually refers to chemicals .
we use chemicals almost everyday.
chemicals makes many things possible like the formation of cosmetics  ,fire extinguishers , fertilizers etc.
we can avoid diseases by the advanced medicines.

then comes the last subject , i.e , physics .
this subject contains , heat , measurement , light , electricity  , sound etc.
physics is more or less related to maths.
the calculations of physics can only be done if we know mathematics.
with the help of physics we can know how things and phenomenons are happening around us.

this in turn will lead to more development.the scientists are still in try to improve gadgets , form new medicines and improve the living conditions of the people on earth.the science is becoming more and more advanced.it can be advanced further.some new diseases are occuring.the scientists are researching for the formation of new and powerful medicines that can cure these unknown disease.

Science is interesting because it is very joyful to learn our world around us. We can know about the our universe , our body , plants feature , kinds of organisms and much more . It includes biology , chemistry and physics . Science is very easy that anyone can learn and understand it and can use it for research . Everyone can be benefited by this .

Through the biology we can able to know about our surrounding . Biology also tell us about us . Our human system , the structure of plants and animals  . We study different organs in our body . We can know about our each body organs system and functions such as heart transfer as blood .

Now the subject is Chemistry . We use chemical in every our work . We use salt   ( Nacl) in our food , we use detergent to wash our clothes , we use fertilizers and pesticides for the good crops etc . Most importantly all the medicines are made up of chemical process . Hence it also give life to organisms . 

And the last is physics . Physics is the most important subject in the science . We can calculate speed of anything , we can calculate heat of anything etc . Through physics we can know  evolution of the universe and atoms.

Also with the help of these subject we can even make machines , robots . We also can find the way how to reduce pollution ( air pollution , water pollution , soil pollution , and noise pollution ) . We can able to remove corruption before it roots us and much more .

Hence Science is very important for the development of our future.

And if our future will be developed then our nation will also become healthy and happy and pollution free .
