NCERT Solutions for Class 4 EVS Our Wondrous World Chapter 10 Our Sky – Question Answers and Exercises for Session 2026-27. These turns everyday sky-watching into a science lesson – why the sky glows orange at sunrise, why shadows stretch long in the morning and shrink to nothing by noon and why the Moon seems to vanish and reappear across the month. Through torch-and-stick experiments, sky-colour observation tables and moon-phase sketches, students discover how the Sun’s changing position explains shadow length and direction, while festivals like Diwali, Eid and Guru Poornima connect these patterns to everyday Indian culture. The chapter closes with India’s Chandrayaan mission, a sky-inspired poem and a riddle about light and shadow. These solutions cover every activity, table and reflection question in the chapter.

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:
- If the Sun moves from East to West, why does it appear to be in the same position at the same time every day?
- Why does the Sun appear to move across the sky when actually the Earth is moving?
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:
In the morning, the Sun is in the eastern sky, so your shadow points westward (opposite to the Sun). In the afternoon, the Sun moves to the western sky, so your shadow points eastward. The length of the shadow would not be the same at both times. Morning and evening shadows are longer because the Sun is lower in the sky. At noon, when the Sun is overhead, shadows are the shortest.
4. Get creative with words
(a) Write your own poem inspired by the beauty of the sky.
Answer:
The sky is wide, the sky is bright,
It shines with stars in the night.
The clouds float softly way up high,
Like cotton boats across the sky.
The Sun and Moon look beautiful,
Making the whole sky wonderful.
(b) Complete the riddle below and answer itโ
Only one colour, but not one size
Appears with light, looks very nice
