Koko:
Owlo, something really strange happened to me today in the garden!
Owlo:
Tell me more, Koko. What did you see out there in the garden?
Koko:
I was looking at a leaf, and I saw these tiny little dots on it. But I couldn't figure out what they were.
Owlo:
That sounds like a wonderful discovery. Some things are simply too small for our eyes to see clearly.
Koko:
But how am I supposed to see them then, Owlo?
Owlo:
A very special instrument was invented for exactly that purpose. It is called a microscope.
Koko:
A micro-scope? That sounds like something you use to scoop ice cream!
Owlo:
That is a very funny thought, Koko. But a microscope is actually an instrument used to look at very tiny things.
Koko:
But how does it actually work, though?
Owlo:
I have an idea. Let us head to the science room. There is a real microscope waiting for us there.
Owlo:
Look, this is the microscope. Do you see those small round pieces of glass at the top?
Koko:
Yes! They sparkle so nicely. What do they do?
Owlo:
Those are called lenses. A lens makes things appear larger than they really are. Just like a magnifying glass.
Koko:
Oh! I have used a magnifying glass before. Everything looked absolutely enormous through it.
Owlo:
Exactly! A microscope uses several lenses together, so things appear even much, much bigger.
Koko:
How much bigger can it make things look?
Owlo:
Some microscopes can make things appear one hundred times larger. Others can make them appear a thousand times larger.
Koko:
A thousand times? Then an ant would look as big as an elephant!
Owlo:
Almost, yes. Shall I place your leaf under the microscope so we can take a look?
Koko:
Yes, please do! I really want to finally see those tiny little dots.
Owlo:
Go ahead and look through this small round opening at the top. That part is called the eyepiece.
Koko:
Wow. I can see tiny little round shapes, all sitting right next to each other. They look a little bit like bubbles.
Owlo:
Those shapes are the cells of the leaf. Every plant, every animal, and even you are made up of cells.
Koko:
I am made of cells? I honestly had no idea about that.
Owlo:
Yes, billions of tiny cells working together make up you, Koko. They are so small that you could never see them with just your eyes.
Koko:
Who actually invented the microscope in the first place?
Owlo:
A spectacle maker from the Netherlands, a very long time ago, around the year sixteen hundred. His name was Zacharias Janssen.
Koko:
So the microscope was actually invented right here in our own country!
Owlo:
That is right, Koko. And thanks to that invention, scientists were able to see the world in a completely new way.
Koko:
I think it is so amazing that there is a whole world out there that you normally cannot see at all.
Owlo:
That is exactly the magic of science. There is always more to discover than what you can see at first glance.
Koko:
Owlo, can you tell me everything we learned today one more time?
Owlo:
I would rather leave that to you. Can you tell me what you discovered today?
Koko:
Okay! A microscope is an instrument with lenses that make very tiny things appear much, much bigger.
Koko:
Things can look up to a thousand times bigger through a microscope. And everything, including me, is made up of tiny things called cells.
Koko:
And the microscope was invented in the Netherlands. So if anyone asks where it came from, I will just say it was invented practically next door!
Owlo:
Perfectly summarised, Koko. I am so proud of your curiosity today.
Koko:
Next time I want to learn what else you can see under a microscope. Maybe even my own hair!
Owlo:
That is a wonderful plan. There is still so very much left to discover.
