Practice Worksheet-our Solar System - EVS - Assignment - Teachmint - Free Printable

Let’s go step by step to fill in the blanks using the words from the box.

We are told:
Words available: giant, Earth, Uranus, planets, Mercury, small, Jupiter, Mars, Sun, rocky, Neptune, Solar System, gas, Venus, star, Saturn

---

First sentence:
> The ______ and the ______ form the ______.

This is about what makes up our system. We know the Sun and the planets together form the Solar System.

So:
→ The Sun and the planets form the Solar System.

---

Next:
> The Sun is an enormous ______.

The Sun is a star — that’s basic astronomy.

→ The Sun is an enormous star.

---

Then:
> Mercury, Venus, Earth and Mars are the four ______ planets.

These are the inner planets — they’re made of rock and metal. So they’re called rocky planets.

→ ...the four rocky planets.

---

Next:
> Jupiter, Saturn, Uranus and Neptune are the four ______ planets.

These are the outer planets — huge and mostly made of gas (or ice giants). They’re called gas giants or just giant planets. Looking at the word box, we have “giant” and “gas”. But note: later sentences refer to them as “giant” when describing size (“largest planet”), so likely here it’s “giant”.

Wait — let’s check context. Later it says “Jupiter... is the largest planet” — which implies “giant” refers to size. Also, “gas” might be used for composition. But the blank says “four ______ planets” — and both “gas” and “giant” are in the box.

Actually, standard teaching: Inner = rocky; Outer = gas giants → but sometimes simplified to “giant planets”.

Looking ahead:
- Fifth planet: Jupiter → “largest planet” → fits “giant”
- Sixth: Saturn → rings → also giant
- Seventh: Uranus → blue/green fog → still giant
- Eighth: Neptune → farthest → still giant

Also, the word “gas” appears only once in the box — probably meant for describing type, not category name.

But wait — there’s a clue: later it says “It has thousands of rings” for sixth planet — that’s Saturn. And “covered with blue and green fog” — that’s Uranus (though actually Neptune is bluer, but often confused).

Back to the blank: “Jupiter, Saturn, Uranus and Neptune are the four ______ planets.”

In many elementary texts, they’re called “gas giants”, but since “gas” and “giant” are separate words, and we need one word per blank, perhaps it’s “giant”.

Alternatively, maybe “gas”? Let’s see if “gas” fits elsewhere.

Later: no other obvious place for “gas” except possibly describing composition — but the blank is for category.

Actually, looking at common curriculum:
Inner planets = terrestrial/rocky
Outer planets = Jovian/gas giants → but again, for simplicity, often called “giant planets”.

Moreover, the word “small” is in the box — probably for contrasting with “giant”.

I think “giant” is correct here.

→ ...the four giant planets.

---

Now, listing planets in order:

> The first planet is ______. It is closest to the Sun.

That’s Mercury.

→ Mercury

> The second planet is ______. It is the brightest planet.

Venus is known as the brightest planet in the sky (after the Moon).

→ Venus

> The third planet is ______. We live on The Blue Planet.

Earth is called the Blue Planet because of its oceans.

→ Earth

> The fourth planet is ______. It is the Red Planet.

Mars is the Red Planet due to iron oxide on its surface.

→ Mars

> The fifth planet is ______. It is the largest planet.

Jupiter is the largest planet in our solar system.

→ Jupiter

> The sixth planet is ______. It has thousands of rings.

Saturn is famous for its prominent ring system — though technically it has many rings, “thousands” is poetic exaggeration, but it’s Saturn.

→ Saturn

> The seventh planet is ______. It is covered with blue and green fog.

Uranus is pale blue-green due to methane in its atmosphere — often described as having a “foggy” appearance.

→ Uranus

> The eighth planet is ______. It is the furthest planet from the Sun.

Neptune is currently the farthest planet (since Pluto is reclassified as dwarf planet).

→ Neptune

Now, let’s double-check all words used:

Used so far:
- Sun
- planets
- Solar System
- star
- rocky
- giant
- Mercury
- Venus
- Earth
- Mars
- Jupiter
- Saturn
- Uranus
- Neptune

Leftover words from box:
Original box:
giant - Earth - Uranus - planets - Mercury - small - Jupiter - Mars - Sun - rocky - Neptune - Solar System - gas - Venus - star - Saturn

We haven’t used: small, gas

Where could they go?

Look back:

After “Mercury, Venus, Earth and Mars are the four rocky planets.” — that’s fine.

Then “Jupiter, Saturn, Uranus and Neptune are the four giant planets.” — we used “giant”.

But what about “small”? Maybe it was meant for contrast? But no blank asks for “small planets”.

And “gas” — perhaps it should be “gas planets” instead of “giant”?

Wait — let’s reconsider that blank.

Some curricula say:
Inner planets = rocky
Outer planets = gas planets

And “giant” might be used later for Jupiter specifically.

But the sentence says: “Jupiter, Saturn, Uranus and Neptune are the four ______ planets.”

If we put “gas”, then “giant” is left — and later, “fifth planet is Jupiter. It is the largest planet.” — which implies “giant” describes size, not category.

But “gas” is more accurate for composition.

However, Uranus and Neptune are sometimes called “ice giants”, not gas giants — but in elementary level, often grouped as “gas planets”.

Also, the word “gas” is in the box — and we haven’t used it yet.

Similarly, “small” is unused.

Perhaps the intended answer for the outer planets is “gas”, and “giant” is for something else? But where?

Wait — look at the very beginning: “The Sun and the planets form the Solar System.” — we used “planets” plural.

Is there a blank that needs “small”? Not obviously.

Another possibility: maybe “small” is for the inner planets? But the blank says “four ______ planets” after listing Mercury to Mars — and we put “rocky”, which is correct.

Perhaps “gas” goes in the outer planets blank.

Let me check online or standard answers for such worksheets.

Upon recall: Many similar worksheets use:

- Inner: rocky
- Outer: gas

And “giant” might be redundant or for emphasis.

But in this case, since “giant” is listed separately, and “gas” is also there, perhaps the outer planets are “gas” planets.

Moreover, later descriptions don’t require “giant” — Jupiter is called “largest”, which implies giant, but the category might be “gas”.

Let’s try swapping:

Suppose:
“Jupiter, Saturn, Uranus and Neptune are the four gas planets.”

Then “giant” is left — but where to use it? No other blank fits.

Unless... is there a mistake?

Wait — the word “small” is also unused.

Perhaps “small” is for the inner planets? But the blank is after listing them, and it says “are the four ______ planets” — if we put “small”, that would be incorrect because while they are smaller than gas giants, they are not typically called “small planets” as a category — “terrestrial” or “rocky” is standard.

In fact, “rocky” is the correct term.

So probably, “gas” is for the outer planets.

Let me confirm with logic:

- Rocky planets: solid surfaces — Mercury, Venus, Earth, Mars
- Gas planets: no solid surface, mostly hydrogen/helium — Jupiter, Saturn; Uranus and Neptune are ice giants but often included.

In many school materials, they simplify to “gas planets” for all four outer ones.

Also, the word “gas” is in the box — must be used somewhere.

Similarly, “giant” might be intended for Jupiter specifically, but the blank is for the group.

Another idea: perhaps “giant” is for the outer planets, and “gas” is not needed? But then “small” is also unused.

Unless “small” is a distractor? Unlikely.

Let’s read the entire text again with current fills:

The Sun and the planets form the Solar System.
The Sun is an enormous star. The planets move around The Sun.
Mercury, Venus, Earth and Mars are the four rocky planets.
Jupiter, Saturn, Uranus and Neptune are the four giant planets.
The first planet is Mercury. It is closest to the Sun.
The second planet is Venus. It is the brightest planet.
The third planet is Earth. We live on The Blue Planet.
The fourth planet is Mars. It is the Red Planet.
The fifth planet is Jupiter. It is the largest planet.
The sixth planet is Saturn. It has thousands of rings.
The seventh planet is Uranus. It is covered with blue and green fog.
The eighth planet is Neptune. It is the furthest planet from the Sun.

Unused words: small, gas

Now, is there any blank that could take “small”? For example, if the inner planets were called “small planets”, but that’s not standard.

Perhaps “gas” is for describing the composition of the outer planets, but the blank is for the category name.

I recall that in some versions, it's "gas giants", but here two separate words.

Another thought: maybe the blank for outer planets is "gas", and "giant" is used for Jupiter in the description, but the description says "largest", not "giant".

The sentence is: "The fifth planet is Jupiter. It is the largest planet." — no blank there.

So "giant" must be used in the category blank.

Perhaps "small" is for the inner planets? Let's try that.

If we put "small" for inner planets: "Mercury, Venus, Earth and Mars are the four small planets." — but that's misleading because Earth is not particularly small compared to some moons, and Venus is similar size to Earth. Also, "rocky" is the scientific term.

Whereas "gas" for outer planets is commonly used.

Let's look for clues in the image description — but I can't describe the image, but the user said not to.

Perhaps the intended answer is:

Outer planets: gas

Then "giant" is left — but maybe it's not used? But all words should be used? The instruction doesn't say to use all words, but typically in such exercises, you use the words provided, and sometimes there are extras, but usually not.

Count the blanks:

1. The ___ and the ___ form the ___. → 3 blanks
2. The Sun is an enormous ___. → 1
3. ...four ___ planets. (inner) → 1
4. ...four ___ planets. (outer) → 1
5. first planet ___ → 1
6. second ___ → 1
7. third ___ → 1
8. fourth ___ → 1
9. fifth ___ → 1
10. sixth ___ → 1
11. seventh ___ → 1
12. eighth ___ → 1

Total blanks: 3+1+1+1+1*8 = 3+1+1+1+8 = 14 blanks.

Words in box: let's count: giant, Earth, Uranus, planets, Mercury, small, Jupiter, Mars, Sun, rocky, Neptune, Solar System, gas, Venus, star, Saturn → 16 words.

So 16 words for 14 blanks — meaning 2 words are extra or not used.

Ah! So not all words are used. That makes sense.

So we can leave out "small" and "gas" if not needed.

But which ones to use?

For the outer planets, "giant" is appropriate because they are much larger than inner planets.

"Gas" might be less accurate for Uranus and Neptune, but "giant" covers size.

In many educational contexts, they are called "giant planets".

For example, NASA calls them "giant planets".

So I'll stick with "giant" for the outer planets category.

Thus, "small" and "gas" are not used — which is fine since there are more words than blanks.

To confirm, let's see if "gas" could fit anywhere else — no.

"Small" — no.

So final decision:

Blanks filled as:

1. Sun
2. planets
3. Solar System
4. star
5. rocky
6. giant
7. Mercury
8. Venus
9. Earth
10. Mars
11. Jupiter
12. Saturn
13. Uranus
14. Neptune

All good.
