Lesson 13 in NCERT’s Class V Environmental Studies textbook describes the amazing journey of “Gaurav Jani”. This lesson is a part of which of the following themes ?

The correct option is Shelter.

Step-by-Step Explanation:

1. Understanding the NCERT Class V EVS Themes:
The Environmental Studies (EVS) curriculum designed by NCERT for primary classes (Classes III to V) is structured around six broad themes to help children view their environment holistically rather than through isolated subject boundaries. These six main themes are:

1. Family and Friends (which includes sub-themes like Relationships, Work and Play, Animals, and Plants)
2. Food
3. Shelter
4. Water
5. Travel
6. Things We Make and Do

2. Analyzing Lesson 13 - "A Shelter So High!":
Lesson 13 of the Class V NCERT EVS textbook is titled "A Shelter So High!". It narrates the journey of Gaurav Jani as he travels on his motorcycle ('Loner') from Mumbai all the way up to the cold, high-altitude desert of Leh and Ladakh, as well as Changthang.

3. Core Focus of the Lesson:
Throughout his amazing journey, Gaurav Jani encounters and documents different types of houses and living arrangements adapted to extreme geographical conditions and climates, such as:

- Houses made of stone, mud, and wood in Leh.
- The Rebo (cone-shaped tents made of yak hair) used by the nomadic Changpa tribe.
- The Donga (houseboats) and carved wooden houses in Srinagar.

Since the entire narrative highlights various kinds of human habitations, construction materials, and adaptations across different regions, this lesson falls under the overarching theme of Shelter.
