Solar System activity for Grade 3 - Free Printable

Let's solve the "Guess the Planets!" worksheet step by step based on the clues and the image of the solar system shown at the bottom.

Here are the planets in order from the Sun (left to right) in the image:
1. Mercury
2. Venus
3. Earth
4. Mars
5. Jupiter
6. Saturn
7. Uranus
8. Neptune

Now, let’s go through each clue:

---

1. It's very big and hot.
- This likely refers to Jupiter or Saturn, but "hot" suggests a gas giant close to the Sun. However, Jupiter is the largest and quite hot due to internal heat. But actually, Venus is very hot (hottest planet) and not that big. Wait — “very big and hot” — the biggest planet is Jupiter, which is also quite hot internally. So Jupiter fits best.
✔ Answer: Jupiter

2. This planet is very close to the sun.
- The closest planet to the Sun is Mercury.
✔ Answer: Mercury

---

3. This planet is red.
- The red planet is Mars.
✔ Answer: Mars

---

4. This is the largest planet.
- The largest planet in our solar system is Jupiter.
✔ Answer: Jupiter

---

5. This planet is our home.
- Our home planet is Earth.
✔ Answer: Earth

6. This planet is very cold and cloudy.
- Neptune is very cold and has stormy, cloudy weather. Uranus is also cold and cloudy. But Neptune is known for its extreme cold and visible cloud layers. Both could fit, but Neptune is often described as cold and cloudy with strong winds.
- However, Venus is also very cloudy (thick CO₂ clouds), but it's hot, not cold.
- So between Uranus and Neptune, both are cold and cloudy. But Neptune is more famously associated with storms and clouds.
- Still, Uranus is cold and has a hazy atmosphere. But Neptune is more commonly described as cold and cloudy.
✔ Best answer: Neptune

Alternatively, if we consider Venus, it's very cloudy but not cold — it's the hottest planet.

So Neptune fits best.
✔ Answer: Neptune

7. This is the planet with rings.
- The most famous ringed planet is Saturn.
✔ Answer: Saturn
