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.

How people live together.
Why societies change over time.
How governments work.
How resources are used.

How geography affects human life.
How history influences the present.
How economic activities meet people's needs.

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.
