Solar System activity for Grade 3 - Free Printable

Let’s go through each sentence one by one and match it to the correct planet.

1. “It’s very big and hot.”
→ The biggest and hottest planet is Jupiter? Wait — actually, Jupiter is the largest, but not the hottest. Venus is hotter! But the clue says “very big AND hot” — so maybe they mean Jupiter? Let’s check other clues first.

Wait — let’s think again. In our solar system:
- Mercury is closest to the Sun → very hot during day.
- Venus is even hotter than Mercury because of its thick atmosphere.
- Jupiter is the largest planet.
But clue #4 says “This is the largest planet.” So that must be Jupiter.

So for #1: “very big and hot” — if “big” means large size, then Jupiter fits. But Jupiter isn’t super hot like Venus or Mercury. Hmm… Maybe this is a trick? Or maybe in simple terms, kids are taught Jupiter is big and has storms (hot inside)? Actually, looking at common school worksheets, sometimes “very big and hot” refers to Venus — but Venus isn’t the biggest.

Wait — let’s look at all clues together:

Clue 2: “very close to the sun” → That’s Mercury

Clue 3: “red” → Mars

Clue 4: “largest planet” → Jupiter

Clue 5: “our home” → Earth

Clue 6: “very cold and cloudy” → Could be Neptune or Uranus, but Neptune is colder. Also, Uranus is icy and cloudy. But often in elementary level, Saturn is known for rings, Neptune for being far and cold. Wait — clue 7 is “planet with rings” → that’s Saturn

So clue 6: “very cold and cloudy” — probably Neptune (farthest, coldest) or Uranus. But since Saturn is taken for rings, and Neptune is bluer and colder, likely Neptune.

Now back to clue 1: “very big and hot” — if we’ve assigned:
- Mercury → #2
- Mars → #3
- Jupiter → #4
- Earth → #5
- Saturn → #7
- Neptune → #6

Then who’s left? Venus!

And Venus is VERY hot — hottest planet — and also fairly big (similar size to Earth). So maybe “very big and hot” = Venus

Yes — that makes sense. Venus is about the same size as Earth (so “big” compared to Mercury/Mars), and it’s the hottest planet.

So final matching:

1. Very big and hot → Venus
2. Very close to the sun → Mercury
3. Red → Mars
4. Largest planet → Jupiter
5. Our home → Earth
6. Very cold and cloudy → Neptune (or Uranus? But Neptune is colder; also, in many diagrams, Neptune is shown as blue/cloudy)
7. Planet with rings → Saturn

Double-checking order from image (left to right):
Sun (not planet), then Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.

In the image below the questions, planets are shown in order:
Small orange (Mercury), yellowish (Venus), blue-green (Earth), red (Mars), striped big (Jupiter), ringed (Saturn), light blue (Uranus), dark blue (Neptune)

So clue 6: “very cold and cloudy” — both Uranus and Neptune fit, but Neptune is farther and colder. However, sometimes Uranus is described as “icy and cloudy”. But in most basic levels, Neptune is the coldest.

Actually, let’s see standard answers for such worksheets:

Commonly:
- Cold and cloudy → Uranus (because it’s tilted and has clouds) OR Neptune

But let’s pick based on typical curriculum:

Often:
- #6: “very cold and cloudy” → Uranus
- #7: rings → Saturn

But wait — Saturn also has clouds and is cold, but it’s famous for rings.

Another way: only 7 clues, 8 planets? No — Pluto is not included. So 8 planets minus Sun = 8, but only 7 clues? Wait no — there are 7 questions, and 8 planets shown? Let’s count the planets in the image:

From left to right after Sun:
1. Mercury
2. Venus
3. Earth
4. Mars
5. Jupiter
6. Saturn
7. Uranus
8. Neptune

That’s 8 planets. But only 7 questions. Which one is missing?

Looking at clues:

We have:
- Mercury (#2)
- Venus (#1)
- Earth (#5)
- Mars (#3)
- Jupiter (#4)
- Saturn (#7)
- ??? for #6 — either Uranus or Neptune

One of them is not used.

Which planet is least likely to be mentioned? Probably Uranus or Neptune.

But clue #6: “very cold and cloudy” — both are, but Neptune is colder. However, in many children’s materials, Uranus is called “the ice giant” and is cloudy.

Actually, let’s search my knowledge: In NASA’s site, Neptune is the windiest and coldest. Uranus is also cold but less extreme.

But perhaps for simplicity, worksheet expects:

#6: Uranus — because it’s often depicted as pale blue and cloudy.

Wait — I recall some worksheets assign:

“Cold and cloudy” → Uranus
“Farthest and coldest” → Neptune

But here it just says “very cold and cloudy” — could be either.

However, looking at the image: the seventh planet from left (after Saturn) is light blue — that’s Uranus. Eighth is darker blue — Neptune.

In the list, clue #6 comes before #7 (“rings”), so maybe #6 is Uranus, #7 is Saturn? No — Saturn is sixth in order.

Order in image:
Position 1: Mercury
2: Venus
3: Earth
4: Mars
5: Jupiter
6: Saturn
7: Uranus
8: Neptune

Clues don’t follow order.

Perhaps safest assignment:

1. Venus (big and hot)
2. Mercury (close to sun)
3. Mars (red)
4. Jupiter (largest)
5. Earth (home)
6. Neptune (coldest)
7. Saturn (rings)

That leaves out Uranus — which is fine, since only 7 clues.

Yes, that works.

Final decision:

1. Venus
2. Mercury
3. Mars
4. Jupiter
5. Earth
6. Neptune
7. Saturn

Let me confirm:

- Venus: second planet, similar size to Earth, surface temp ~467°C — very hot → fits "very big and hot" (big relative to inner planets)
- Mercury: closest to Sun → yes
- Mars: red due to iron oxide → yes
- Jupiter: largest → yes
- Earth: our home → yes
- Neptune: average temp -214°C, has clouds → very cold and cloudy → yes
- Saturn: prominent rings → yes

Perfect.

Final Answer:
1. Venus
2. Mercury
3. Mars
4. Jupiter
5. Earth
6. Neptune
7. Saturn
