✏️ Section 3 — Worked Examples

🔶 Example 1: Which Age?

People used tiny stone tools. They painted animals on cave walls. Which age is this?

1Think: What age had tiny tools? Microliths = tiny stone tools
2Think: What age had cave paintings? Cave art = Mesolithic feature
3Both clues point to the same age.
✔ Answer: This is the Mesolithic Age (Middle Stone Age). It had microliths and cave art.

🔶 Example 2: Which Civilisation?

People wrote on clay tablets. They used wedge-shaped marks. Which civilisation is this?

1Think: Who wrote on clay? Mesopotamians used clay tablets
2Think: What is wedge-shaped writing? Cuneiform = wedge writing
3Cuneiform was invented by Sumerians in Mesopotamia.
✔ Answer: This is the Mesopotamian civilisation (Sumerian people). They invented cuneiform.

🔶 Example 3: Timeline Order

Put these in the correct order: Bronze Age, Neolithic, Palaeolithic, Iron Age.

1Which came first? Palaeolithic = Old Stone Age = oldest
2Which came second? Neolithic = New Stone Age = next
3Which came third? Bronze Age = metals came after stone
4Which came last? Iron Age = strongest metal = newest
✔ Answer: Palaeolithic → Neolithic → Bronze Age → Iron Age

Part B: True or False — Answers

Part C: Solve These — Answers

C1. Cave paintings and tiny stone blades (microliths) belong to the Mesolithic Age (Middle Stone Age). Reason: Cave paintings showing hunting scenes and microliths used as arrows/spears are the key markers of this period, roughly 10,000 – 6,000 BCE.

C2. Two features of a Sindhu-Sarasvati city showing it was well-planned: (a) Grid-plan streets — roads crossed each other at right angles like a chessboard. (b) Covered drainage system — underground brick drains ran below the streets to carry away waste water.

C3. Cuneiform is a wedge-shaped writing made by pressing a reed stylus into wet clay tablets. It was used in Mesopotamia. Hieroglyphics is a picture-based writing system where symbols represent words or sounds, written on papyrus or stone walls. It was used in Egypt.

Part D: Match the Columns — Answers

Part E: Draw and Label — Guide

Draw a long horizontal line (the timeline). Mark five points from left to right: Palaeolithic (big rough stones), Mesolithic (tiny stone blades and cave art), Neolithic (farming and pottery), Bronze Age (bronze tools and early cities), Iron Age (iron tools and kingdoms). Draw a small picture above each point and write the approximate time period.
