Chapter 1: Understanding Social Science

The Big Questions

What does 'Social Science' really mean, and why does it matter?

How is Social Science different from the natural sciences?

Which disciplines make up Social Science, and what does each study?

Why should we study Social Science at all?

Introduction

In Grades 6 to 8 you explored Social Science through stories of people, places and events. Grade 9 begins by stepping back to ask what the subject truly is.

Social Science is the systematic study of human society. It tells us not only what happened or where things are, but also why events occur, how people live together, how environments influence life, how governments function, how economies operate, and how the past and present together shape the world.

While Physics, Chemistry and Biology study the natural world, Social Science focuses on society, institutions, cultures and human interactions.

Key Concepts

Social Science in Everyday Life

Think of one ordinary day: your house is built from materials sourced from many places; your food is harvested, processed, transported, bought and sold by many people; you travel on roads planned by public authorities; your school is shaped by educational policies; your electricity comes from distant power stations through a vast network. Even the simplest activity depends on governance, economic production, social cooperation and the natural environment.

The chapter asks questions such as:

Why do some people live in crowded cities and others in scattered villages?

Why do some regions depend on farming while others focus on industry or trade?

Why are certain regions more prone to floods?

How does climate change influence our lives?

Society does not function by chance — it is shaped by history, geography, institutions, resources and human choices. Social Science answers such questions through careful observation, evidence and logical reasoning.

Understanding Society through Time and Traditions

Society has changed greatly over thousands of years — from communities depending directly on nature, to growing crops, domesticating animals, building settlements, exchanging goods and organising governance. Villages grew into towns, towns into cities.

India's knowledge traditions valued discussion, questioning and logical reasoning:

Pañchamahābhūtas (five great elements) — earth (Pṛithvī), water (Āpaḥ), fire (Agni), air (Vāyu) and space (Ākāśha) — describe nature as an interconnected system in which human life is embedded.

Vasudhaiva kuṭumbakam — 'the world is one family' — expresses the interconnectedness of human societies.

The Arthaśhāstra, attributed to Kauṭilya and composed about 2,300 years ago, examined administration, economic management, taxation and the duties of rulers.

Modern social scientists continue this legacy: they observe lives, conduct interviews and surveys, examine documents and compare times and places, building explanations supported by evidence.

Social Science as a Study of Disciplines

No single field can explain society. A drought, for example, affects crops (environment), farmers' incomes (economy), relief measures (politics), migration to cities (society) and traditional ways of coping (culture). In Grades 9–10, Social Science draws mainly on four core disciplines:

Geography — the Earth, its environments, and people–surroundings relationships. It combines spatial (location) and temporal (change over time) perspectives and uses maps, globes, atlases, GIS and infographics. NCERT's School Bhuvan portal lets you map your own village or city.

History — the human past. India's itihāsa-purāṇa tradition preserved cultural memory through stories; modern historiography relies on empirical evidence using genetics, carbon-14 dating and archaeology. Sources include literary (e.g. the Sāmaveda manuscript, palm-leaf Tirukkuṟaḷ), archaeological (terracotta figurines, sculptures), epigraphic (Brahmi inscription of the Gupta period, Krishnadeva Raya's Kannada inscription at Hampi) and numismatic (Samudragupta's 4th-century coin, Jahangir's zodiac coin).

Political Science — governance, power, constitutions and institutions. Early Indian thought linked politics with dharma, artha and rājadharma; texts like the Mahābhārata, Śhukranīti and especially the Arthaśhāstra discussed governance. The Panchayati Raj system shows grassroots democracy today.

Economics — how societies use limited resources, and how goods and services are produced, exchanged and distributed. India was for centuries a leading economy; colonial rule brought poverty, famines and decline of traditional industries; since independence India has rebuilt through infrastructure, education, technology and poverty reduction.

Other disciplines — Sociology, Philosophy, Anthropology, Psychology — also belong to the Social Science family and will be studied in higher grades.

Why Study Social Science?

It explains how the systems around you (housing, water, roads, markets, digital spaces) developed and whom they affect.

It explains diversity of languages, customs and occupations — and the underlying unity of Indian culture.

It prepares you to take part responsibly in civic life in a democracy.

It builds the habit of asking informed questions about shared problems like public health or urban growth.

It connects the past, present and future.

The Future of Social Science

New technologies, expanding cities, environmental concerns, migration and global connections make Social Science more important. It will help address climate change, sustainable development, social harmony and equitable use of resources.

Think About It / Let's Analyse

Let's Analyse: identify a change in your locality over the past five years (transport, housing, education, technology or environment). What was it like before, what changed, why, and how did it affect people?

Let's Explore: map your village or city on the School Bhuvan portal.

Key Terms

Vasudhaiva kuṭumbakam — the world is one family (वसुधैव कुटुम्बकम्)

Arthaśhāstra — Kauṭilya's text on statecraft (अर्थशास्त्र)

Empirical evidence — information from actual observation or experiment (अनुभवजन्य साक्ष्य)

Genealogical records — sources tracing family lineage (वंशावली अभिलेख)

Epigraphic source — inscriptions on stone, metal or rock (अभिलेखीय स्रोत)

Look at any news headline — a flood, a new law, rising prices — and you will find geography, history, politics and economics all tangled together. That is exactly why Social Science studies society as one connected story.

Common Mistakes

Thinking Social Science is only about memorising dates, maps and definitions — the book says it is about understanding people, places, society, culture and power.

Confusing epigraphic sources (inscriptions) with numismatic sources (coins).

Saying Social Science has only four subjects — the four are core for Grades 9–10; others like Sociology and Psychology are also part of it.

Questions and Activities (Hints)

For a 'drought' style question, show how each of the four disciplines looks at the same event.

For classifying sources, ask: is it written text, material object, inscription, or coin?

For 'why study Social Science', link it to citizenship, diversity and future choices.

💡 Key Learning Points

✓Social Science is the systematic study of human society — explaining why and how, not just what and where.
✓Everyday life depends on systems of governance, economy, social cooperation and the environment.
✓Grades 9–10 draw on four core disciplines: Geography, History, Political Science and Economics.
✓Historians use literary, archaeological, epigraphic and numismatic sources along with scientific methods.
✓Indian traditions like the Pañchamahābhūtas, vasudhaiva kuṭumbakam and the Arthaśhāstra show a long history of systematic social thinking.

👨‍🏫 Teaching Tips

→Start with the 'one day in your life' walk-through and let students list every system they depend on before breakfast.
→Run the Let's Analyse activity: groups report one local change from the last five years using the four guiding questions.
→Use the drought example as a board diagram with five branches (environment, economy, politics, society, culture).
→Bring pictures of a coin, an inscription and a manuscript and have students classify each source type.
→Demonstrate the NCERT School Bhuvan portal so students can locate their own school or village.
→Hold a short discussion on how the Arthaśhāstra and Panchayati Raj connect ancient and modern ideas of governance.
→End with each student writing one 'why' question about their locality that Social Science could answer.

📋 Assessment Questions
