Our Sky: the Chapter Story
A short read for Class 4 before you play. These notes are written for this page and are not copied from the textbook.
🌅 A sky that keeps changing
Look up in the morning, in the afternoon and at night, and the sky looks different each time. The Sun may look orange at sunrise, strong at noon and gone at night, when the Moon and stars appear. Birds, animals, plants and people also change what they do as the day goes by.
☀ The brightest object
The Sun is the brightest object in the sky. It is so bright that we cannot see other stars while it shines. It gives us light and heat. Each day it seems to rise in the East, climb overhead and set in the West.
👤 Shadows on the move
Your shadow runs when you run and changes shape when you pose. Morning shadows are long, noon shadows are short and evening shadows are long again, but on the opposite side. This happens because the Sun moves across the sky.
🔦 Torch and stick
In a dark room, a torch and a stick can copy the Sun and a tree. A stick close to the torch makes a bigger shadow, and moving the torch to another side moves the shadow too.
🕰 Sundials and shadow puppets
Long ago people noticed that shadows help to tell the time and built the sundial. Raja Jai Singh built Jantar Mantar, whose Samrat Yantra works like a giant sundial. Shadow puppetry has also been enjoyed in India for a long time.
🌙 Moon and stars
After sunset thousands of stars twinkle, and the Moon looks like the biggest object in the night sky. Its shape changes from a full circle to a C and sometimes it cannot be seen. Many festivals, such as Diwali and Eid, follow these changes. In 2023, India’s Vikram Lander reached the Moon.

Our Sky Class 4 FAQs
What is Our Sky in Class 4 EVS?

Why does the colour of the sky change?
The sky looks different in the morning, afternoon and at night, and the Sun's colour also seems to change. Children draw the sky at each time and note their observations in a table.
What is the Sun's journey across the sky?
The Sun appears to rise in the East, move up until it is overhead at noon and then move down towards the West. The Sun is the brightest object in the sky and gives us light and heat.
Why do shadows change during the day?
Shadows are long in the morning, short at noon and long again in the evening. The evening shadow falls in the opposite direction to the morning shadow, because the Sun moves across the sky.
How does the torch and stick activity work?
In a dark room, shine a torch on a stick and move the stick or the torch. A stick close to the light gives a bigger shadow, and changing the torch's direction changes the direction of the shadow.
