Building Our Homes: Materials and Methods

Let's become architects for a day! We will investigate the amazing world of houses, from simple village huts to tall city buildings, and uncover the secrets of how and why they are built.

Activity 01

Maker Learning45 min · Small Groups

Model House Makers

In small groups, students use clay, twigs, straw, ice cream sticks, and cardboard to build models of different house types like a kutcha hut, a pucca house, or a stilt house. This hands-on activity helps them understand how different materials are used in construction.

Identify three natural materials used for building houses.

Facilitation TipProvide picture cards of different houses as a reference for each group to build from.

What to look forConduct a 'Think-Pair-Share' where students first think about a question (e.g., 'What material would you use to build a house in a very hot place?'), then discuss with a partner, and finally share their ideas with the class.

Material Sort and Match

Give students cards with names or pictures of materials (brick, mud, bamboo, glass, steel) and house types (igloo, apartment, hut). Students work in pairs to sort the materials into 'natural' and 'man-made' categories and then match them to the correct house type.

Explain why houses in rainy areas often have sloping roofs.

Facilitation TipAfter the activity, discuss why certain materials are used for specific houses.

What to look forA worksheet containing a 'match the following' section (house type to region), fill-in-the-blanks about materials, and short answer questions like 'Why do houses in rainy areas have sloping roofs?'.

Climate and Homes Detective

Show students images of houses from different regions of India (e.g., Kerala, Rajasthan, Himachal Pradesh). Students must guess the climate of the region (hot, rainy, snowy) based on the house's design, like its roof type, windows, and materials.

Compare the materials used to build a kutcha house and a pucca house.

Facilitation TipUse a map of India to point out the locations and discuss the geography of each place.

What to look forProvide students with a simple checklist with 'I can' statements, such as 'I can name two materials used for a kutcha house' or 'I can explain why houseboats are found in Kashmir'.

A few notes on teaching this unit

Begin by tapping into students' own experiences, asking about their homes. Use a rich variety of visuals: photos, short video clips, and even a map of India to make the connection between geography and housing clear. Prioritise hands-on activities, like building models with clay and sticks, to make abstract concepts about materials and structure concrete and memorable.

By the end of this journey, your students will be able to identify various building materials and explain why a house in the mountains of Himachal looks so different from a house in the backwaters of Kerala.


Watch Out for These Misconceptions

  • Kutcha houses are weak and not good homes.

    Kutcha houses are made from locally available natural materials like mud and bamboo. They are cost-effective and designed to suit the local climate, for example, mud walls keep the house cool in summer. They are less permanent than pucca houses but are not necessarily 'bad' homes.

  • All strong houses must be made of brick and cement.

    While brick and cement make very strong, permanent houses, other materials can also be very strong. For instance, houses made of stone or thick wood have been standing for hundreds of years. In earthquake-prone areas, flexible bamboo houses can be safer than rigid brick ones.

  • A sloping roof is only for snow.

    Sloping roofs are excellent for snowy regions as they prevent snow from piling up. However, they are also very important in areas with heavy rainfall, as they allow rainwater to drain away quickly and prevent the roof from leaking or collapsing.
