NCERT Intext Questions (Page 155)

Answer: A shadow changes when the position of the Sun changes during the day, such as in the morning, afternoon, or evening. The shape of the shadow also changes if the shape or position of the body changes.

Only objects that block light completely can form clear shadows, and when the object moves, its shadow moves along with it.

These changes occur because the Sun’s position in the sky keeps shifting, which affects the size and direction of the shadow.

No, shadows are not formed only by the Sun. They can also be created using other light sources like a torch or a lamp, as long as the light is blocked by an object.

Find Out (Page 156)

Let us try something interesting.

1. Take a torch and a stick. Close the doors and windows to make the room dark.
2. Hold the stick in one place and turn on the torch. Shine the torchlight on the stick.
3. Observe the changes in the shadow of the stick, in the following situations:

• Move the stick back and forth.

• Change the direction of the torch.

Think and answer the following questions.

Question. If we change the distance of the source of light from the stick (an object), how will the shadow change?

Answer: When a light source is placed near an object, the shadow appears larger. As the light source is moved farther away, the shadow becomes smaller.

Question. If we change the direction of the torch (source of light), how will the shadow change?

Answer: When the torch is turned in a different direction, the shadow shifts as well and appears on the side opposite to the light source.

Discuss with your friends:

Question. Is there a pattern to the way the shape of the Moon changes?

Answer: Yes, the Moon’s shape changes in a regular cycle. It gradually grows from a new Moon to a full Moon and then slowly shrinks until it becomes invisible again, returning to the new Moon. This pattern continues repeatedly.

Question. Are there days when the Moon is not visible in the sky?

Answer: Yes, there are certain nights when the Moon cannot be seen at all. Such a night is known as Amavasya or the New Moon night.

Let Us Reflect (Pages 162-163)

Question 1. Give two differences between:

(a) Day and night
(b) Sky in the morning and in the evening
(c) Our activities during the day and at night
(d) Activities of animals during the day and at night.

Answer:

(a)
Day: The Sun can be seen and the sky remains bright.
Night: The sky is dark, and the Moon and stars are visible.

(b)
Morning: The sky turns orange as the Sun rises in the east.
Evening: The sky takes on reddish-orange shades as the Sun sets in the west.

(c)
Day: People usually go to school or work, play, and carry out daily tasks.
Night: People have dinner, complete homework, and rest or sleep.

(d)
Day: Many animals such as cows, dogs, birds, squirrels, and butterflies are active during daylight. They move around and search for food.
Night: Some animals, like owls and bats, are active after dark. They hunt or look for food at night, while most other animals rest or sleep.

Question 2. Enquire about something

A teacher said that the Sun appears to move from East to West during the day. Meera is curious about this statement and has some questions for her teacher. List at least two questions that she can ask.

Answer:

Meera might ask questions such as:

• What causes the Sun to seem as if it is moving across the sky?
  
  

• Does the Sun actually move, or is this movement due to the Earth’s motion?

Question 3. Figure it out

Suppose you stand at the same spot during the morning and the afternoon. In the morning, your shadow points in one direction, while in the afternoon it points in another. Why? Would the length of your shadow be the same at both times?

Answer: No, the shadow does not remain the same in length or direction throughout the day.

In the morning, when the Sun rises in the east, the shadow is long and falls towards the west.

At noon, the Sun is almost overhead, so the shadow becomes very short.

In the afternoon, as the Sun moves towards the west, the shadow grows longer again and appears in the opposite direction, towards the east.

Question 4. Get creative with words

(a) Write your own poem inspired by the beauty of the sky.

(b) Complete the riddle below and answer it –

Only one colour, but not one size Appears with light, looks very nice What is it?

Answer:

(a)
The sky stretches wide, glowing bright,
Blue in the day, dark at night.
Orange at dawn, red at dusk,
With the Moon and stars shining above us.

(b)
It has one colour but keeps changing size,
Forms in the light before your eyes.
It moves along wherever you go,
And fades away when the light is low.

What is it?

Shadow
