8. Identify Orion and label Sirius
Answer:
- Orion contains three bright stars in a straight line (Orion’s Belt).

9. Why do stars appear at dusk and fade away at dawn? Why can’t we see them in daytime?
Answer:
Stars remain in the sky all the time, but during the day, the sunlight is extremely bright.
This bright light scatters in the atmosphere and hides the light of distant stars from our eyes.
Hence, stars are visible only at night when sunlight does not overpower their light.
10. Does the Big Dipper appear to move?
Answer:
Yes.
The Big Dipper appears to change its position during the night.
This happens due to the rotation of the Earth on its axis.
The Pole Star, however, appears nearly fixed.
Students are expected to draw a diagram showing the changing orientation.
11. Think about the night sky and write a poem or story.
Answer (model example):
The night sky glows with shining light,
Stars sparkle softly through the night.
Patterns form high in the sky,
Like hunters, bulls, and birds that fly.
The universe whispers tales untold,
Of galaxies bright and wonders bold.
