Mohenjo-daro: Urban Planning & Drainage

Active learning helps students connect abstract archaeological concepts to tangible evidence from Mohenjo-daro. By handling replicas of artefacts, examining diagrams, and discussing peer insights, students move beyond textbook descriptions to understand urban planning as a lived reality of the Harappan people.

Activity 01

• Gallery Walk
• 30 min · Small Groups

Gallery Walk: The Harappan Menu

Posters around the room display data on seeds found in different regions (e.g., millets in Gujarat, rice in Lothal). Students circulate to identify regional dietary variations and the environmental factors behind them.

Analyze how Mohenjo-daro's urban planning reflects social hierarchy.

Facilitation Tip

During the Gallery Walk, place enlarged images of Harappan wheat, barley, and animal bones at eye level so students can observe details like grain size and bone cuts for meat extraction.

What to look for

Pose the question: 'If you were an archaeologist discovering Mohenjo-daro today, what specific features of the Citadel and Lower Town would most strongly suggest a social hierarchy, and why?' Allow students to share their interpretations and justify their reasoning with evidence from the text or images.

Activity 02

• Inquiry Circle
• 40 min · Small Groups

Inquiry Circle: Irrigation Tech

Groups are assigned a specific Harappan site (e.g., Dholavira, Shortughai) and must use provided evidence to explain how that specific community managed water, whether through reservoirs or canals.

Explain what the sophisticated drainage system reveals about Harappan hygiene and engineering.

Facilitation Tip

For the Collaborative Investigation, provide a map of Shortughai with marked irrigation channels and ask groups to trace routes using the terracotta plough model to understand slope and water flow.

What to look for

Provide students with a simple diagram of a Harappan street with houses and drains. Ask them to label two key components of the drainage system and write one sentence explaining the purpose of each. Check for accurate identification of drains and their function in waste removal.

Activity 03

• Think-Pair-Share
• 20 min · Pairs

Think-Pair-Share: Domestic vs. Wild

Pairs look at images of animal bones found at sites. They discuss how archaeologists distinguish between domesticated cattle and hunted wild animals, and what this tells us about Harappan society.

Differentiate the functions and significance of the Citadel versus the Lower Town.

Facilitation Tip

In Think-Pair-Share, give each pair a list of animal bones found at Harappan sites and ask them to categorise them as domesticated, wild, or aquatic before discussing their findings with the class.

What to look for

Students create a Venn diagram comparing the Citadel and the Lower Town. They then exchange diagrams with a partner. Each partner checks if at least three distinct features are listed for each area and if one shared characteristic is identified. Partners provide feedback on clarity and accuracy.

A few notes on teaching this unit

Teachers should avoid presenting Harappan urban planning as a single achievement. Instead, treat it as a system where diet, drainage, and division of labour interacted. Use artefacts like pottery shards with grain impressions or children’s toys of oxen to show how daily life supported urban living. Research shows that students grasp complex societies better when they analyse multiple small pieces of evidence rather than one grand narrative.

By the end of these activities, students will confidently describe Harappan diet, irrigation methods, and urban structures with evidence. They will also compare social spaces like the Citadel and Lower Town, using archaeological data to support claims about hierarchy and function.

Watch Out for These Misconceptions

• During the Gallery Walk activity, watch for statements like 'Harappans only ate vegetarian food.'

  During the Gallery Walk, if students make this claim, direct them to the section on animal bones. Ask them to note the presence of fish vertebrae or cattle ribs in the display and discuss how these remains suggest a mixed diet.

• During the Collaborative Investigation activity, watch for comments like 'Agriculture was primitive and lacked technology.'

  During the Collaborative Investigation, when students examine the terracotta plough model or images of furrowed fields, ask them to trace the grooves and compare them to modern plough marks. This helps them see the technical precision in Harappan farming tools.
