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 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.
