Science Second Grade worksheet - Free Printable

Let’s solve this step by step.

We have two parts to the worksheet:

Part 1: Match the pictures with the correct words

There are four cute cartoon images at the top:
- First image: A smiling sun in a blue sky → that’s the sun
- Second image: A smiling moon in a starry night sky → that’s the moon
- Third image: A smiling Earth with green land and blue oceans → that’s the earth
- Fourth image: A smiling yellow star → that’s a star

So, under each picture, we write the matching word from the options given: “star”, “sun”, “moon”, “earth”

Order of pictures left to right:
1. Sun → write “sun”
2. Moon → write “moon”
3. Earth → write “earth”
4. Star → write “star”

Wait — let’s double-check the order of the word boxes below them. The word boxes are arranged as:
[star] [sun] [moon] [earth]

But those are just labels for you to choose from — they’re not in order under the pictures. You need to pick the right word for each picture above.

So:
- Picture 1 (Sun) → match with “sun”
- Picture 2 (Moon) → match with “moon”
- Picture 3 (Earth) → match with “earth”
- Picture 4 (Star) → match with “star”

That part is straightforward.

Part 2: Match the diagrams with “revolution” or “rotation”

Left diagram: Shows the Earth going around the Sun in an oval path. It says “Revolution” on the orbit arrow, and “Rotation” near the spinning Earth. But the whole diagram is about the Earth moving *around* the Sun — that’s called revolution.

Right diagram: Shows the Earth spinning on its own axis (with arrows showing spin), and also has a satellite orbiting it — but the main focus here is the Earth turning on itself. That’s called rotation.

The question gives us two blank boxes under the diagrams, and two word choices: “revolution” and “rotation”

So:
- Left diagram (Earth orbiting Sun) → revolution
- Right diagram (Earth spinning on axis) → rotation

This matches what science teaches:
- Rotation = spinning on your own axis (like a top)
- Revolution = going around something else (like Earth going around the Sun)

Now, putting it all together:

Top row (pictures):
1. Sun → sun
2. Moon → moon
3. Earth → earth
4. Star → star

Bottom row (diagrams):
Left → revolution
Right → rotation

Final Answer:

Top blanks (left to right):
sun
moon
earth
star

Bottom blanks (left to right):
revolution
rotation
