MORE ABOUT
SCIENCE
It is important that when a
discovery is made, it must be communicated to other scientists so that they can
use the necessary knowledge in their own research work. This way, it would lead
to a faster usage of the discovery and many people would benefit.
We generally read about
certain facts in our school books and often wonder how it can be proved.
Scientists always carry out ‘Experiments’ to prove certain things. For example,
the fact that the earth revolves around the sun, was first proved by the
astronomers before it was accepted by the general public.
‘Science’ comes from the
Latin word ‘to know’. Therefore, Science is Knowledge.
Scientists use knowledge to
discover how and why things happen. They use this knowledge to change or stop
something from happening ---- for example, certain diseases can be stopped or
even an earthquake can be prevented from happening.
There are two main areas of
science known as the branches of science. They are Physics Sciences and the
Life Sciences. Physics and Chemistry are Physical Sciences while Biology and
Medicine are Life Sciences.
Experiments by scientists
are carried out in laboratories. Sometimes, it may take many years of very hard
work and research in these laboratories before a scientist is able to solve a problem.
One of the best ways to
learn is to carry out experiments. Many simple experiments or ‘do-it-yourself’
exercises are recommended in science textbooks. These may be tried out by you
to learn facts.
