From the earliest times, humans have been curious about
the world about them. Their observation of natural
phenomena and their search for the reasons behind such
phenomena led them to gradually understand the world.
Science is the systematic study of the natural world
through observation and experimentation
Natural science
is the study of the physical world Physics is a branch
of natural science) (Chemistry and biology are other
branches.) Physics observes nature, looks for a general
pattern in the behaviour of things, and comes up with laws
that help us to predict the movements and interactions of
objects and the forces that act on them.

THE SCIENTIFIC METHOD
If we understand a phenomenon, we can invent ways to
control it or take advantage of it. The topic of interest
may be an apple falling from a tree, or even light from
a distant galaxy. The scientific method is a step-by-step
method to study occurrences in nature.
A scientist can start with a guess, but it must then
be experimentally verified by themselves as well as
by others. Science is ever changing. As experimental
techniques and instruments improve over time, new
theories must be found to explain new observations. A
verified theory is taken as valid until it is disproved by a
new experimental result.
