Multiple Choice Questions:

1. A star is an object in space that...
Stars are made of hot gases (mostly hydrogen and helium) and give off light and heat. So “both b and c” is correct → ✔ Correctly marked as c

2. Even though Earth is just a medium size star, about how many Earths could fit inside the Sun?
Actually, Earth is NOT a star — it’s a planet! But if we ignore that mistake and focus on the number: The Sun is so big that about 1 million Earths can fit inside it. So answer a. 10? No. b. 1,000,000? Yes! → ✘ Student chose d, which is wrong. Should be b

3. To us, the Sun looks brighter and bigger than other stars in the sky because...
It’s not because it has more hydrogen or is hotter — it’s because it’s much closer to us than any other star. → ✔ Correctly marked as c

4. What two kinds of energy does Earth get from the Sun?
We get light (so we can see) and heat (to keep us warm). That’s basic solar energy. → Answer: Light and Heat

True/False Questions:

5. Write T or F:

1. *The core of the Sun is the coolest part of the Sun.*
→ FALSE. The core is the HOTTEST part — where nuclear fusion happens. → ✔ Marked F — correct

2. *The sunspots or dark areas on the Sun’s surface are the cooler parts of the Sun’s surface.*
→ TRUE. Sunspots are slightly cooler than surrounding areas. → ✔ Marked T — correct

3. *The Sun is mainly made up of two gases called hydrogen and helium.*
→ TRUE. About 74% hydrogen, 24% helium. → ✔ Marked T — correct

4. *The core of the Sun is the hottest part of the Sun.*
→ TRUE. Millions of degrees! → ✔ Marked T — correct

5. *The corona is the name for the center of the Sun.*
→ FALSE. Corona is the outer atmosphere, visible during eclipses. Center = core. → ✔ Marked F — correct

6. *The core is the name of the center of the Sun.*
→ TRUE. → ✔ Marked T — correct

7. *The corona is a layer of hot gases on the surface of the Sun that extend out into space.*
→ TRUE. It’s the outermost layer, very hot, extends far out. → ✔ Marked T — correct

8. *Solar flares are dark cool spots on the Sun.*
→ FALSE. Solar flares are EXPLOSIONS of energy — bright and hot. Dark cool spots = sunspots. → ✔ Marked F — correct

9. *Solar flares are violent eruptions of hot gases that flare out from the surface of the Sun.*
→ TRUE. Exactly right. → ✔ Marked T — correct

10. *Solar flares are made of liquid hydrogen found deep inside the Sun.*
→ FALSE. Flares happen on the surface/atmosphere, not deep inside, and they’re plasma/gas, not liquid. → ✔ Marked F — correct

11. *Life on Earth could exist without the Sun.*
→ FALSE. No sunlight = no photosynthesis = no food chain = no life as we know it. → ✔ Marked F — correct

12. *The Milky Way is the center of our Solar System.*
→ FALSE. The Sun is the center of our Solar System. Milky Way is our galaxy. → ✔ Marked F — correct

13. *The Sun is the center of our Solar system.*
→ TRUE. All planets orbit the Sun. → ✔ Marked T — correct

Only one error: Question #2 should be b. 1,000,000, not d.

Also, note: In question #2, the statement says “Earth is just a medium size star” — that’s scientifically incorrect (Earth is a planet), but since the question is asking about volume comparison, we still answer based on the intended meaning.
