Germs activity for year 4 - Free Printable

Let’s go step by step to fill in the blanks correctly.

We’re talking about germs — tiny things that can make us sick. The text is explaining what germs are and how we know about them.

1) “They ___ in you, on you and around you...”
Germs live everywhere — inside our bodies, on our skin, and all around us. So the word here should be live.

2) “...but you ___ see them.”
Germs are too small to see with just your eyes. You need a microscope. So you cannot or can’t see them. Let’s use can’t for simplicity.

3) “What are they? They’re ___.”
The whole worksheet is titled “WHAT ARE GERMS?” so this blank is asking for the name of these tiny things. Answer: germs.

4) “Germs are ___ living things.”
Germs are alive — they grow, reproduce, etc. But they’re very small. So we say they’re tiny living things. (Some might say “microscopic,” but “tiny” fits better for young students.)

5) “You can see them only through a ___.”
To see something super small like germs, you need a special tool — a microscope.

6) “Some germs can make you ___...”
When germs get into your body, they can cause illness. So they make you sick.

7) “...so doctors work hard to ___ more about them.”
Doctors study germs to learn how to stop them from making people sick. So they work hard to learn more about them.

Now let’s double-check each answer makes sense in the sentence:

- They live in you, on you and around you → ✔️
- but you can’t see them → ✔️
- What are they? They’re germs → ✔️
- Germs are tiny living things → ✔️
- You can see them only through a microscope → ✔️
- Some germs can make you sick → ✔️
- so doctors work hard to learn more about them → ✔️

All answers fit logically and grammatically.

Final Answer:
1) live
2) can’t
3) germs
4) tiny
5) microscope
6) sick
7) learn
