The Solar System interactive activity for Grade 3 - Free Printable

Let’s solve this step by step.

First, we need to label the planets in order from the Sun outward. The solar system has 8 planets (plus the Sun and other objects). From closest to farthest from the Sun:

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

Also, “The Sun” is the big orange star on the left.
“Outer space” is the dark background with stars — that goes in the empty area not pointing to any planet or sun.
“The Milky Way” is our galaxy — it’s also part of outer space but usually shown as a band of stars; since there’s only one box for it, we’ll put it where the starry background is labeled.

Now let’s match each blank in the picture based on position:

- Leftmost big orange object → The Sun
- First small grayish planet after Sun → Mercury
- Second yellowish planet → Venus
- Third blue-green planet → Earth
- Fourth reddish planet → Mars
- Fifth huge striped planet → Jupiter
- Sixth planet with rings → Saturn
- Seventh light blue planet → Uranus
- Eighth deep blue planet → Neptune

Then the boxes pointing to the background:
- One box points to the starry sky → outer space
- Another box might point to the same or nearby → The Milky Way (since both are about the universe beyond planets)

But looking at the layout: There are two boxes near the top right and bottom right that likely refer to the background. Since “The Milky Way” is specific, and “outer space” is general, we can assign:

→ Box pointing to the star field behind Neptune/Uranus → outer space
→ Box pointing to the wider galaxy view (maybe the faint band) → The Milky Way

Actually, in most diagrams like this, “The Milky Way” isn’t always labeled unless specified — but since it’s in the word bank, and there’s a box pointing to the starry region, we’ll use it.

Wait — let’s count the blanks in the image description:

From left to right:

1. Pointing to Sun → The Sun
2. Pointing to first planet (small gray) → Mercury
3. Pointing to second planet (yellow) → Venus
4. Pointing to third planet (blue) → Earth
5. Pointing to fourth planet (red) → Mars
6. Pointing to fifth planet (big striped) → Jupiter
7. Pointing to sixth planet (rings) → Saturn
8. Pointing to seventh planet (light blue) → Uranus
9. Pointing to eighth planet (dark blue) → Neptune
10. Two more boxes: one probably pointing to the background between Mars and Jupiter? Or above? Actually, looking again — there are 11 boxes total? Wait no — let me recount from your image description.

Actually, from the original problem setup, here’s how many labels we have to place:

Word bank:
Jupiter, Mars, Neptune, Earth, Saturn, Uranus, The Sun, outer space, Venus, The Milky Way, Mercury → That’s 11 words.

In the diagram, there are 11 white boxes to fill.

So:

Positions (left to right):

Box 1: Points to Sun → The Sun
Box 2: Points to first planet (closest to Sun) → Mercury
Box 3: Points to second planet → Venus
Box 4: Points to third planet → Earth
Box 5: Points to fourth planet → Mars
Box 6: Points to fifth planet (largest) → Jupiter
Box 7: Points to sixth planet (with rings) → Saturn
Box 8: Points to seventh planet → Uranus
Box 9: Points to eighth planet → Neptune
Box 10: Points to the starry background → outer space
Box 11: Also points to background/galaxy → The Milky Way

Yes — that uses all 11 words.

Now, the matching section:

Match each planet with its fact.

Left column:
Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus (note: typo in image says “Unanus”, should be Uranus)
Neptune

Right column facts:

A. is the largest planet. → Jupiter
B. has rings of rock and ice. → Saturn (though Uranus and Neptune also have rings, Saturn’s are most famous and made of ice/rock)
C. is the furthest planet from the sun. → Neptune
D. is the coldest planet. → Neptune (farthest = coldest)
E. is also called the Red planet. → Mars
F. is the second closest planet to the Sun and the closest to Earth. It is the hottest. → Venus
G. is the only planet where life exists. → Earth
H. is the closest planet to the Sun. → Mercury

Note: Some facts could apply to multiple, but we pick the best fit.

For example:
- “has rings of rock and ice” — Saturn is known for prominent icy rings.
- “coldest planet” — Neptune, because it’s farthest.
- “furthest planet” — Neptune (Pluto is not considered a planet anymore).

Also note: Uranus is sometimes colder than Neptune due to internal heat differences, but generally Neptune is accepted as coldest in school curricula.

So matches:

Mercury → H
Venus → F
Earth → G
Mars → E
Jupiter → A
Saturn → B
Uranus → ? Wait — what’s left? We have 8 planets and 8 facts.

Facts listed:

1. is the largest planet. → Jupiter
2. has rings of rock and ice. → Saturn
3. is the furthest planet from the sun. → Neptune
4. is the coldest planet. → Neptune? But we can’t use Neptune twice.

Problem: Two facts seem to go to Neptune.

Let’s list facts again clearly:

Right column:

- is the largest planet. → Jupiter
- has rings of rock and ice. → Saturn
- is the furthest planet from the sun. → Neptune
- is the coldest planet. → Neptune (but conflict)
- is also called the Red planet. → Mars
- is the second closest... hottest → Venus
- is the only planet where life exists → Earth
- is the closest planet to the Sun → Mercury

That’s 8 facts for 8 planets.

But “is the coldest planet” and “is the furthest planet” both point to Neptune — which is fine if we allow one planet to have two facts? No — the instruction says “match each planet with the information about it” — implying one-to-one.

Wait — perhaps “is the coldest planet” refers to Uranus? Because Uranus has no internal heat source and can get colder than Neptune sometimes. In some educational materials, Uranus is called the coldest.

Let me check standard curriculum:

Typically:

- Coldest planet: Neptune (average temp -214°C) vs Uranus (-216°C) — actually Uranus is slightly colder on average! But many sources say Neptune.

However, in this worksheet, since “furthest” must be Neptune, and “coldest” might be assigned to Uranus to avoid duplication.

Looking at the word bank — they spelled it “Unanus” — probably a typo for Uranus.

And in the matching, they have “Unanus” listed — so we’ll treat it as Uranus.

To resolve:

Assign:

- Furthest planet → Neptune
- Coldest planet → Uranus (to make unique matches)

Because otherwise we’d have two facts for Neptune and none for Uranus.

Similarly, “has rings” — Saturn is primary, but Uranus and Neptune also have rings. However, Saturn’s are iconic.

So final matching:

Mercury → is the closest planet to the Sun.
Venus → is the second closest planet to the Sun and the closest to Earth. It is the hottest.
Earth → is the only planet where life exists.
Mars → is also called the Red planet.
Jupiter → is the largest planet.
Saturn → has rings of rock and ice.
Uranus → is the coldest planet. *(assigning here to avoid duplicate)*
Neptune → is the furthest planet from the sun.

This gives each planet one unique fact.

Now, back to labeling the diagram.

Final labeling order from left to right (based on positions):

Assuming the boxes are placed as follows (from typical solar system diagram):

Top row boxes (above planets):

- Above Sun: The Sun
- Above Mercury: Mercury
- Above Venus: Venus
- Above Earth: Earth
- Above Mars: Mars
- Above Jupiter: Jupiter
- Above Saturn: Saturn
- Above Uranus: Uranus
- Above Neptune: Neptune

Bottom row boxes (below or beside):

- Below Mercury or near start: outer space
- Near end or background: The Milky Way

But without seeing exact arrow positions, we rely on standard order.

Since the user will drag and drop, we just list correct assignments per position.

But for answer, we need to provide the filled labels.

Perhaps list them in order of appearance from left to right in the diagram.

From the image description:

There are 11 boxes. Let's number them 1 to 11 from left to right as they appear visually.

Box 1: points to Sun → The Sun
Box 2: points to first planet (Mercury) → Mercury
Box 3: points to second planet (Venus) → Venus
Box 4: points to third planet (Earth) → Earth
Box 5: points to fourth planet (Mars) → Mars
Box 6: points to fifth planet (Jupiter) → Jupiter
Box 7: points to sixth planet (Saturn) → Saturn
Box 8: points to seventh planet (Uranus) → Uranus
Box 9: points to eighth planet (Neptune) → Neptune
Box 10: points to background (say, between Mars and Jupiter or top) → outer space
Box 11: points to another background area → The Milky Way

Yes.

Now for matching:

We'll write pairs.

Final Answer:

Labeling the Solar System Diagram (in order from left to right as per typical layout):

1. The Sun
2. Mercury
3. Venus
4. Earth
5. Mars
6. Jupiter
7. Saturn
8. Uranus
9. Neptune
10. outer space
11. The Milky Way

Matching Planets to Facts:

- Mercury → is the closest planet to the Sun.
- Venus → is the second closest planet to the Sun and the closest to Earth. It is the hottest.
- Earth → is the only planet where life exists.
- Mars → is also called the Red planet.
- Jupiter → is the largest planet.
- Saturn → has rings of rock and ice.
- Uranus → is the coldest planet.
- Neptune → is the furthest planet from the sun.

Note: For "coldest planet", we assigned to Uranus to ensure each planet has one unique fact, though scientifically Neptune is often cited. This avoids duplication since "furthest" must be Neptune.

All set.
