Shelter — Study Notes for TN TET (Paper I, EVS)

Overview

Shelter is one of the three basic human needs alongside food and clothing. In the TN TET Paper I Environmental Studies section, this topic tests your understanding of why living beings need shelter, the diversity of human houses across regions and climates, traditional and modern building materials, and how animals create or find their homes.

Questions typically appear as direct factual recall (e.g., "Which material is used in kutcha houses?"), picture-based identification of house types, or reasoning questions linking climate to shelter design. Since EVS is integrated and child-centred, expect questions that connect shelter to local context—Tamil Nadu's traditional houses, coastal vs hilly dwellings, and animals found in the state's ecosystems.

Mastering this topic requires you to remember specific house-type names, match materials to regions, and recall animal homes with their scientific or common names. The pedagogy angle may ask how to teach shelter through activity-based learning or field visits.

Key Concepts

• **Purpose of shelter**: Protection from weather (heat, cold, rain), safety from wild animals and intruders, privacy, rest and storage of belongings.

• **Factors influencing house design**: Climate (hot/cold/rainy), locally available materials, occupation of people (farmers, nomads, fishers), economic status and cultural traditions.

• **Kutcha vs Pucca houses**: Kutcha houses use natural, temporary materials (mud, thatch, bamboo); Pucca houses use permanent materials (bricks, cement, steel, concrete).

• **Regional house types in India**: Igloos (snow, Arctic), stilt houses (flood-prone areas like Assam, Kerala backwaters), houseboats (Kashmir, Kerala), tents (Rajasthan nomads, Ladakh), bungalows and flats (urban areas).

• **Tamil Nadu traditional houses**: Tiled-roof houses in villages, Chettinad mansions with Burma teak and Athangudi tiles, coastal huts with coconut-leaf thatch.

• **Animal homes terminology**: Each animal has a specific home name—nest (birds), den (lion), burrow (rabbit), hive (bees), stable (horse), kennel (dog), etc.

• **Adaptation in animal shelters**: Animals choose or build shelters suited to survival—insulation, camouflage, protection of young, food storage.

• **Changing shelters**: Nomads and migratory animals do not have permanent shelters; they move based on season, food or occupation.
