Lesson 2: Unlocking the Secrets of Mohenjodaro

In this Grade 6 History Alive! The Ancient World lesson, students explore how artifacts and ruins from Mohenjodaro reveal details about daily life in the Indus valley civilization, including its city planning, trade practices, and public structures like the Great Bath. Students analyze physical evidence such as standardized weights, a scale, and architectural remains to understand how archaeologists draw conclusions about ancient cultures. The lesson also examines competing theories about the mysterious decline of the Harappan civilization around 1900 B.C.E.

Section 1

Artifacts Reveal Mohenjodaro's Secrets

Key Idea

The people of the Indus Valley did not leave behind written records that historians can read today. Their system of pictographs remains largely undeciphered. For thousands of years, the story of their lives was a mystery.

To uncover this story, historians rely on archaeological evidence. Archaeologists study the physical objects, or artifacts, that people left behind. These clues help them understand how ancient people lived.

Section 2

Indus Valley People Plan Advanced Cities

Key Idea

The city of Mohenjodaro reveals incredible urban planning. Its streets formed a neat grid layout, much like a modern city. This careful organization suggests the Indus Valley people had strong leaders and a detailed plan before they started building.

Residents enjoyed advanced technology that made life cleaner. A complex sewer system with clay pipes ran beneath the streets, carrying wastewater away from homes. This was one of the world's first major sanitation systems.

Section 3

Cultures Blend to Shape Ancient India

Key Idea

After the great Indus cities faded, new groups of people, like the Aryans, moved into the region. The Aryans were nomadic herders with their own language and beliefs, which they brought with them.

Over many centuries, the traditions of the original Indus Valley people and the newly arrived Aryans began to blend. This slow mixing of ideas, beliefs, and ways of life is known as cultural diffusion.

Section 4

Historians Re-examine a Civilization's End

Key Idea

The great Indus cities eventually faded. While historians once believed in a violent invasion, evidence now suggests that natural events, like earthquakes or massive floods, may have changed the course of the Indus River.

This environmental shift would have ruined farming and disrupted trade. People slowly abandoned the cities, leading to the end of this advanced civilization.
