Worksheet online exercise for Grade 6 - Free Printable

Let’s go step by step through each question in Part A. We’re matching planet descriptions to the correct planet name.

---

1. This planet is called the “morning star” or “evening star”?
→ That’s Venus. It’s often visible just before sunrise or after sunset, so people used to call it that.

2. This planet has 2 moons and when we look at it in the sky it looks red.
→ That’s Mars. It’s known as the Red Planet, and it has two small moons: Phobos and Deimos.

3. The “Olympic Mons” volcano is located on this planet.
→ Actually, it’s Olympus Mons (not Olympic), and it’s on Mars — the biggest volcano in the solar system!

Wait — but Mars was already used in #2. Let’s double-check:
Yes, Olympus Mons is definitely on Mars. So maybe #2 and #3 are both Mars? But usually worksheets don’t repeat answers unless specified. Let’s hold that thought.

Actually, let’s re-read #2: “has 2 moons and looks red” → still Mars.
#3: “Olympus Mons” → also Mars. Hmm. Maybe the worksheet allows repeats? Or perhaps I misread?

Wait — no, actually, looking again:
In real science, only Mars fits both. But let’s check if any other planet could fit #3? No — Olympus Mons is uniquely on Mars.

So maybe the worksheet expects Mars for both? But that seems odd. Let’s keep going and see.

Actually — correction: In some contexts, teachers might accept Mars for both, but let’s verify all others first.

4. This planet is counted as the largest planet in the solar system?
→ That’s Jupiter. It’s a gas giant and way bigger than Earth.

5. This planet has just the right conditions for life, it is not too hot not too cold.
→ That’s Earth. Our home planet — perfect temperature range for liquid water and life.

6. This planet has the hottest surface temperature of all the planets in the solar system?
→ Even though Mercury is closest to the Sun, Venus is hotter because of its thick atmosphere trapping heat (greenhouse effect). Surface temp ~470°C.

7. The nearest planet to the Sun in the solar system!
→ That’s Mercury. Closest orbit to the Sun.

8. The farthest planet to the Sun in the solar system!
→ As of now (and since Pluto was reclassified as a dwarf planet in 2006), the farthest *planet* is Neptune.

9. The giant red spot planet in the solar system!
→ That’s Jupiter. The Great Red Spot is a huge storm that’s been raging for centuries.

Wait — Jupiter was already used in #4. Again, possible repeat? Let’s note that.

10. The 3rd largest planet that look like a smooth, bluish-green beach ball!
→ Size order:
1. Jupiter
2. Saturn
3. Uranus ← yes! Uranus is third largest. And it’s blue-green due to methane in its atmosphere. Looks like a smooth ball.

11. This planet cannot be seen with the naked eyes and has the highest wind speed recorded on any planet in the solar system?
→ Cannot be seen with naked eye → must be very faint or distant.
Highest wind speeds → Neptune! Winds up to 2,100 km/h. Also, Neptune is barely visible without telescope under perfect conditions — most people can’t see it easily. So this fits.

But wait — #8 said Neptune is farthest. Now #11 also says Neptune? Possible repeat?

Let’s list what we have so far:

1. Venus
2. Mars
3. Mars (Olympus Mons)
4. Jupiter
5. Earth
6. Venus (hottest surface)
7. Mercury
8. Neptune
9. Jupiter (Great Red Spot)
10. Uranus
11. Neptune (winds + hard to see)

So repeats:
- Mars appears twice (#2 and #3)
- Venus appears twice (#1 and #6)
- Jupiter appears twice (#4 and #9)
- Neptune appears twice (#8 and #11)

Is that okay? Well, scientifically, those facts are correct. Some planets do match multiple descriptions.

But let’s double-check #3: Is there any chance “Olympic Mons” refers to something else? No — it’s definitely Olympus Mons on Mars. Typo in worksheet (“Olympic” instead of “Olympus”), but meaning is clear.

Also, #6: Hottest surface — Venus, yes. Not Mercury. Correct.

#11: Highest winds — Neptune, yes. And it’s not easily visible to naked eye — true. Most people need binoculars or telescope.

So even though some planets repeat, the answers are factually correct.

Alternatively, maybe the worksheet intends unique answers? Let’s think…

Wait — for #3, is there ANY other planet with a famous volcano? Io (moon of Jupiter) has volcanoes, but it’s not a planet. Venus has volcanoes too, but none named “Olympus Mons”. Only Mars has that.

So no — #3 must be Mars.

Similarly, #9: Only Jupiter has the Great Red Spot.

So repeats are necessary here.

Perhaps the teacher designed it this way intentionally.

Final mapping:

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

That’s consistent with science.

Now, let’s write them in order.
