Chapter 1: Understanding Social Science

Topic 1: What Is Social Science?


What Is Social Science?

Introduction

Human beings do not live alone. They live in families, villages, towns, cities, states and countries. They interact with nature, use resources, form governments, develop cultures, exchange goods, create traditions and solve problems together.

The study of all these human activities is known as Social Science.

Social Science helps us understand how people live, think, work, govern, produce, trade and interact with each other and with their environment. It explains not only what happened in the past but also why it happened, how it affects the present and how it can influence the future.

Unlike natural sciences, which study nature and physical objects, Social Science studies human society and human behaviour.


Definition of Social Science

Social Science is the systematic study of human society, human behaviour, relationships, institutions, cultures, economies, governments and the interaction between people and their environment.

Simple Definition

Social Science is the study of people, society and the world in which they live.


Meaning of Social Science

The word Social refers to people living together in society.

The word Science means knowledge obtained through careful observation, investigation, evidence and logical reasoning.

Therefore,

Social Science means the scientific study of society using facts, evidence and logical thinking.

Social scientists do not depend only on opinions or guesses. They collect information, analyse evidence, compare different viewpoints and then reach conclusions.


Why is Social Science Called a Science?

Many students think only Physics, Chemistry and Biology are sciences.

However, Social Science is also a science because it follows a systematic method.

Social scientists

  • Observe society carefully.
  • Collect evidence.
  • Study historical records.
  • Conduct surveys.
  • Analyse data.
  • Compare different situations.
  • Draw logical conclusions.

Although human behaviour changes over time, Social Science studies it using scientific methods.

1. Human Society

Nature of Social Science

Social Science has several important characteristics.

1. It studies human society.

It explains how people live together and organise their lives.

2. It is evidence-based.

Conclusions are based on facts, historical sources, maps, surveys, statistics and observations.

3. It is interdisciplinary.

It combines Geography, History, Political Science and Economics to understand society completely.

4. It studies change.

Society keeps changing due to technology, population growth, climate, economy and politics.

5. It develops critical thinking.

Students learn to question, analyse and understand problems instead of memorising facts.


Objectives of Social Science

The main objectives are to

  • Understand society.
  • Learn from history.
  • Respect different cultures.
  • Protect the environment.
  • Become responsible citizens.
  • Develop logical thinking.
  • Solve social problems.
  • Make informed decisions.

Difference Between Natural Science and Social Science

Natural Science

Social Science

Studies nature

Studies society

Studies plants, animals and physical objects

Studies people and human behaviour

Examples: Physics, Chemistry, Biology

Examples: Geography, History, Political Science, Economics

Mostly deals with natural laws

Deals with human behaviour and society

Experiments are common

Surveys, observations and historical evidence are commonly used


Importance of Social Science

Social Science is important because it helps us

  • understand our society,
  • know our rights and responsibilities,
  • respect diversity,
  • understand different cultures,
  • protect natural resources,
  • appreciate democracy,
  • make better decisions,
  • solve community problems,
  • become responsible citizens.

Without Social Science, it would be difficult to understand why societies develop differently or how governments, economies and cultures influence our daily lives.


Real-Life Examples

Example 1

Heavy rainfall causes floods.

A Social Scientist studies

  • why floods occur,
  • how people are affected,
  • government relief measures,
  • economic losses,
  • environmental impact.

Example 2

Food prices suddenly increase.

Social Science explains

  • demand and supply,
  • inflation,
  • transport costs,
  • government policies,
  • effect on families.

Example 3

People vote during elections.

Social Science helps us understand

  • why elections are held,
  • how governments are formed,
  • citizens' rights,
  • democratic participation.
