This document provides an introduction to the field of science. It defines science as a systematic body of knowledge based on facts gathered through observation, experimentation and experience. Science aims to formulate verifiable conclusions or laws. The document outlines the major fields of science including natural sciences like biology and physical sciences, as well as social sciences and applied sciences. It provides examples of biological sciences like zoology and botany, and physical sciences including physics, chemistry and geology. The scientific method is described as using a logical process of reasoning involving stating a problem, formulating a hypothesis, testing the hypothesis by gathering and analyzing data, and reaching a conclusion. Physics is presented as the foundation for technology.

1. Introduction
to the World
of Science

2. “Nature and Nature’s laws
lay hid in night
God said, let Newton be!
And all was light.
-Alexander Pope

3. Have you ever wondered
why the sky is blue and the
sunset red?
How and why things work?
How do you hear and see?
Why is life so different
today than four centuries
ago?

4. What is Science?
 The word science comes from
the Latin "scientia," meaning
knowledge
 "knowledge attained through
study or practice” (According to
Webster's New Collegiate
Dictionary)

5. Science refers to a system
of acquiring knowledge…
Why?

6. Science iS…
a systematized body of
knowledge that is based on facts
gathered through
observations, experiences and
experiments in order to formulate a
verifiable conclusion or law that
serves as basis of technology for the
benefit of man and his environment.

7. Fields of science are commonly
classified along two major lines:
 Natural sciences
-the study of the natural world
 Socialsciences
-the systematic study of human
behavior and society

8. Applied Science
- the application of the
theoretical sciences, like those in
social and natural sciences.

10. What is Biological
science?
the scientific study of life
or living things

11. What is Physical
science?
It
deals with the study of
nonliving things.

12. What is Physics?
 It
deals with the understanding of the
fundamental laws of nature.
 The branch of science concerned with
the properties of matter and energy and
the relationships between them. It is
based on mathematics and traditionally
includes mechanics, optics, electricity
and magnetism, acoustics, and heat.

13. It is a way of thinking.
it makeS you aSk “why?”
all the time.

14. Why does Physics can not be
considered as a natural
philosophy?
because it employs the
scientific method

15. What is Scientific
Method?
Itis the application of a logical
process of reasoning to arrive
at a certain law or principle
that is consistent with
experimental results.
