Sun Worksheet - FREE - Free Printable

Let’s go step by step to fill in each blank using the word bank.

Word Bank:
star, Proxima Centauri, gas, Earthlings, brighter, rocket, Earth, 157,000, billions, feet, Sun, down, reason, planet

---

First sentence:
“Our Sun is different from _______ Earth.”
→ We’re comparing the Sun to Earth. The blank should be “Earth” — but wait, that would say “different from Earth Earth”? That doesn’t make sense.
Actually, looking again: it says “Our Sun is different from _______ Earth.”
Hmm… maybe it’s “our”? But “our” isn’t in the word bank.
Wait — perhaps it’s a typo or misphrasing? Let’s read the whole thing.

Actually, let’s look at context:
“Our Sun is different from _______ Earth. How so? Our _______ is a giant ball of burning _______!”

Ah! Maybe the first blank is meant to be “our”? But “our” isn’t in the word bank. Wait — perhaps it’s “the”? Not there either.

Hold on — maybe it’s “Earth” as in “different from Earth” — and the word “Earth” is used once here. Then later we have “Our _______ is a giant ball...” — that must be “Sun”.

Let me try filling logically:

1. “Our Sun is different from Earth.” → Makes sense. Sun vs Earth.
2. “How so? Our Sun is a giant ball of burning gas!” → Yes, Sun is made of gas (plasma, but for kids, “gas” is fine).
3. “The Sun is a star.” → Correct.
4. “Look down. Are your feet on fire? Hopefully not.” → Silly joke — look down at your feet, are they on fire? No. So “down” and “feet”.
5. “Earth is a planet, not a star...” → Already used “Earth” once? Wait, we used it in #1. Can we reuse words? The instructions don’t say no reuse, but usually in these worksheets, you use each word once. Let’s check the word bank count.

Word bank has 15 words. Let’s count blanks:

Blanks in text:

1. different from ___ Earth → blank before “Earth”
2. Our ___ is a giant ball → blank
3. burning ___ → blank
4. Sun is a ___ → blank
5. Look ___ → blank
6. your ___ on fire → blank
7. ___ is a planet → blank
8. some of the ___ of stars → blank
9. bigger and ___ and hotter → blank
10. One simple ___ → blank
11. traveled by ___ → blank
12. to ___ , the next closest star → blank
13. take ___ years → blank
14. to ___ than any other star → blank

That’s 14 blanks. Word bank has 15 words — so one word won’t be used? Or maybe I miscounted.

List of blanks with line numbers:

Line 1: “different from _______ Earth.” → Blank 1
Line 2: “Our _______ is” → Blank 2
Line 2: “burning _______!” → Blank 3
Line 3: “is a_______.” → Blank 4
Line 4: “Look _______.” → Blank 5
Line 4: “your _______ on fire?” → Blank 6
Line 6: “_______ is a planet,” → Blank 7
Line 9: “some of the _______ of stars” → Blank 8
Line 10: “bigger and _______ and hotter” → Blank 9
Line 13: “One simple _______ :” → Blank 10
Line 14: “by _______ to the Sun,” → Blank 11
Line 15: “to _______________, the next” → Blank 12 (long blank)
Line 16: “take _______ years!” → Blank 13
Line 18: “to ___________ than any other star.” → Blank 14

Yes, 14 blanks. Word bank has 15 words. So one word is extra? Or maybe “Earth” is used twice? Let’s proceed carefully.

Try assigning:

Blank 1: “Our Sun is different from Earth.” → But then it says “Earth” right after — so “different from Earth Earth”? That can’t be. Unless it’s “different from our Earth” — but “our” not in bank.

Wait — maybe it’s “different from the Earth” — but “the” not in bank.

Perhaps it’s a mistake in my reading. Let me re-read the original text:

“Our Sun is different from _______ Earth. How so? Our _______ is a giant ball of burning _______!”

Maybe the first blank is “our”? Not in bank.

Another idea: perhaps it’s “different from planet Earth”? But “planet” is in bank.

Try: “Our Sun is different from planet Earth.” → That makes sense! Sun is a star, Earth is a planet.

Then: “Our Sun is a giant ball of burning gas!” → Good.

“The Sun is a star.” → Good.

“Look down. Are your feet on fire?” → Funny, but logical.

“Earth is a planet, not a star...” → Now we use “Earth” here. But we already used “planet” in blank 1? Wait, if blank 1 is “planet”, then “Earth” is still available.

But in blank 1, if we put “planet”, then it reads: “different from planet Earth” — which is correct.

Then blank 7: “_______ is a planet” — that should be “Earth”.

So:

Blank 1: planet
Blank 2: Sun
Blank 3: gas
Blank 4: star
Blank 5: down
Blank 6: feet
Blank 7: Earth

Now: “When you look at the night sky, you see only some of the _______ of stars in our universe.”

→ Should be “billions” — because there are billions of stars.

Blank 8: billions

“Lots of stars are bigger and _______ and hotter than our Sun.”

→ “brighter” — since bigger stars are often brighter.

Blank 9: brighter

“So why does our Sun look like the biggest and brightest one? One simple _______ : it’s the closest to us.”

→ “reason”

Blank 10: reason

“If you traveled by _______ to the Sun, it would take about 7 months.”

→ “rocket”

Blank 11: rocket

“If you traveled in that same rocket to _______________, the next closest star after our Sun,”

→ “Proxima Centauri” — that’s the name of the next closest star.

Blank 12: Proxima Centauri

“it would take _______ years!”

→ From knowledge, it’s about 157,000 years with current tech. And “157,000” is in the word bank.

Blank 13: 157,000

“Because the Sun is so close, it appears much MUCH bigger and brighter to ___________ than any other star.”

→ Who sees it? “Earthlings” — meaning people on Earth.

Blank 14: Earthlings

Now, what words did we use?

Used:
planet, Sun, gas, star, down, feet, Earth, billions, brighter, reason, rocket, Proxima Centauri, 157,000, Earthlings

Leftover: “feet” was used, “down” used, “rocket” used... wait, all 14 used? Word bank had 15: let's list them:

Word bank:
star — used (blank 4)
Proxima Centauri — used (blank 12)
gas — used (blank 3)
Earthlings — used (blank 14)
brighter — used (blank 9)
rocket — used (blank 11)
Earth — used (blank 7)
157,000 — used (blank 13)
billions — used (blank 8)
feet — used (blank 6)
Sun — used (blank 2)
down — used (blank 5)
reason — used (blank 10)
planet — used (blank 1)

That’s 14 words. What’s missing? Oh — “feet” is listed, and we used it. All accounted for? Wait, the word bank also has “feet” and “down” etc. — I think I have all.

But in the word bank, there’s also “feet” — yes, used.

Wait, the word bank as written:

star
Proxima Centauri
gas
Earthlings
brighter
rocket
Earth
157,000
billions
feet
Sun
down
reason
planet

That’s 14 words? Let me count:

1. star
2. Proxima Centauri
3. gas
4. Earthlings
5. brighter
6. rocket
7. Earth
8. 157,000
9. billions
10. feet
11. Sun
12. down
13. reason
14. planet

Yes, 14 words. And 14 blanks. Perfect.

Now, let’s write the filled text to verify:

“Our Sun is different from planet Earth. How so? Our Sun is a giant ball of burning gas! The Sun is a star.
Look down. Are your feet on fire? Hopefully not.
Earth is a planet, not a star, and Earth is not burning up.
(Sure, we have forest fires and volcanoes but that is not the same as the whole world being on fire all the time.)
Our Sun is not the only star. When you look at the night sky, you see only some of the billions of stars in our universe.
Lots of stars are bigger and brighter and hotter than our Sun. There are also many that are smaller and dimmer and cooler. Our Sun is a medium-sized star.
So why does our Sun look like the biggest and brightest one? One simple reason: it’s the closest to us. If you traveled by rocket to the Sun, it would take about 7 months. If you traveled in that same rocket to Proxima Centauri, the next closest star after our Sun, it would take 157,000 years! Because the Sun is so close, it appears much MUCH bigger and brighter to Earthlings than any other star.”

Perfect — makes sense and uses all words correctly.

Final Answer:
planet, Sun, gas, star, down, feet, Earth, billions, brighter, reason, rocket, Proxima Centauri, 157,000, Earthlings
