• The Sun is very huge.

• About 1 million Earths can fit inside the Sun!

Q3. Is the Sun a planet?

• No, the Sun is not a planet.

• It is a star made of very hot gases.

Q4. How hot is the Sun?

• The Sun is very, very hot.

• Its surface has hot gases that make it shine.

Q5. Which gas from the Sun is used to fill balloons?

• Helium gas is found in the Sun.

• It is the same gas used in balloons.

• Helium makes about 27.4% of the Sun.

Post-class Questions

Q1. Can we live on the Sun?

• No, we cannot live on the Sun because it is too hot.

Q2. What will happen if there is no Sun in our Solar System?

• There will be no light, no heat, and no life on Earth.

MODULE 5: THE CHANGING SHADOWS

Pre-Class Analysis (Brainstorming Questions)

1. Have you seen your shadow looking long in the morning and short at noon?

2. Do you think shadows look different in summer and winter?

3. When the Sun is high in the sky, will your shadow be long or short?

4. When the Sun is low in the sky, what will your shadow look like?

5. Can you name the four seasons of the year?

---

Class Notes (Q & A)

Q1. Why do shadows change in size?
A1. Shadows change because the Sun moves high and low in the sky at different times.

Q2. What happens to the Sun and shadows in summer?
A2. In summer, the Earth tilts towards the Sun. The Sun is high in the sky and our shadows look shorter.

Q3. What happens to the Sun and shadows in winter?
A3. In winter, the Earth tilts away from the Sun. The Sun is low in the sky and our shadows look longer.

Q4. Can you name the four seasons and their months?
A4.

• Summer – March, April, May, June

• Rainy/Monsoon – July, August, September

• Winter – October, November, December, January

• Spring – February, March

Post Class Activity 

1. Draw your shadow in the morning, noon, and evening.
 (Morning = long, Noon = short, Evening = long)




Sunrise Postions

MODULE 5 : THE REASONS OF SEASONS

Pre-Class Analysis (Brainstorming Questions)

1. Does the Sun rise in the same direction every day?

2. Why do we see changes in sunrise and sunset positions during the year?

3. What could be the connection between the Sun’s position and the seasons we experience?

---

Class Notes (Q & A)

Q1. Does the Sun rise from the same direction daily?
Ans: No. The Sun rises exactly in the east only on two days in a year. These two days are called the Equinoxes – 21st March (Spring Equinox) and 23rd September (Autumn Equinox).

Q2. How does the position of the Sun at sunrise change the seasons?

Ans: The shifting position of the Sun across the horizon causes variation in the length of days and nights, which leads to different seasons.

Q3. Why do seasons occur on Earth?
Ans: Seasons occur because of the tilt of the Earth’s axis and its revolution around the Sun.

Q4. What happens on Summer Solstice and Winter Solstice?
Ans:

• Summer Solstice (21st June): The longest day and shortest night in the Northern Hemisphere.

• Winter Solstice (22nd December): The shortest day and longest night in the Northern Hemisphere.

Q5. How are day length and night length related to seasons?
Ans:

• Longer days and shorter nights → Summer

• Shorter days and longer nights → Winter

Post Class Activity 

Draw positions of Sun and Earth during four seasons.
