Chapter 1: Understanding Social Science – Complete Notes (Part 1)

1. What is Social Science?

Social Science is the systematic study of human society. It helps us understand how people live together, interact with one another, and organise their lives. It explains the relationship between people, society, government, economy, environment, and culture.

Unlike natural sciences, which study nature, Social Science studies human life and society.

In Simple Words:- Social Science is the study of people, their behaviour, their history, their environment, and the way society functions.

• Social Science Helps Us Understand
• How people live together.
• Why societies change over time.
• How governments work.
• How resources are used.
• How different cultures develop.
• How geography affects human life.
• How history influences the present.
• How economic activities meet people's needs.

• Reflection
• Dialogue

Ancient Indian thinkers believed that knowledge should be gained through questioning and logical thinking.

Panchamahabhutas (Five Great Elements):- According to Indian philosophy, nature is made up of five basic elements.

1. Social Science as a Group of Disciplines

Human society is very complex, so no single subject can explain every aspect of it. Therefore, Social Science is a combination of different disciplines, each studying a particular part of human life. Together, these disciplines help us understand society in a complete and connected way.

Why Do We Need Different Disciplines?:- A single event can affect many areas of society.

Example: Drought, A drought affects:

• Environment → Less rainfall and water shortage.
• Economy → Farmers lose crops and income.
• Politics → Government provides relief measures.
• Society → People migrate to cities for work.
• Culture → Traditional methods of saving water become important.

Thus, one situation can be studied from different perspectives.

Four Core Disciplines of Social Science:- In Classes 9 and 10, Social Science mainly consists of four subjects:

1. Geography:- Studies the Earth, environment, and human interaction with nature.

2. History:- Studies the past and how societies have changed over time.

3. Political Science:- Studies government, democracy, laws, rights, and governance.

4. Economics:- Studies production, distribution, consumption, and use of resources.

Together, these subjects provide a holistic understanding of society.

• Sociology
• Anthropology
• Philosophy
• Psychology

These subjects are studied in greater detail in higher classes.

2. Geography:- Geography is the study of the Earth, its physical features, human activities, and the relationship between people and their environment. It explains where things are located, why they are located there, and how places influence one another.
