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.

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 has clouds. But Neptune is known for being extremely cold and having strong winds and clouds.
- Alternatively, Venus is very cloudy, but it's hot, not cold.
- So, the coldest and cloudy ones are Uranus and Neptune.
- Between them, Neptune is colder and more famous for its storms and cloud cover.
✔ Answer: Neptune (or possibly Uranus, but Neptune is better fit)

But wait — let’s check: Uranus is tilted and has methane clouds, and Neptune is even colder with visible storms like the Great Dark Spot.

However, both are cold and cloudy. But Neptune is often described as "cold and cloudy."

✔ Answer: Neptune
