Koko:
Owlo! Owlo! Look at my scarf. Mom wrapped it around me three times this morning!
Owlo:
Good morning, Koko! That scarf looks very cozy. It must be very cold outside today.
Koko:
It is SO cold. And when I walked here, little white fluffy things kept falling on my nose. It tickled!
Owlo:
Those fluffy white things are called snowflakes, Koko. And you picked a perfect day to visit.
Koko:
Owlo, why does snow fall from the sky? Where does it even come from?
Owlo:
What a wonderful question. Let me think of the best way to explain this. Come with me to the science lab.
Koko:
Ooh, I love the science lab. It smells like crayons and something fizzy in here.
Owlo:
Now, Koko, do you know what clouds are made of?
Koko:
Umm, fluffy stuff? Like cotton?
Owlo:
Great guess! They actually look like cotton, but they are made of tiny, tiny drops of water. Very, very small ones.
Koko:
Tiny water drops are floating up in the sky? That is so strange and cool at the same time.
Owlo:
It really is! Now, you know how water in your cup feels cold when it comes from the fridge?
Koko:
Yes! I always try to drink it super fast before it gets warm again.
Owlo:
Well, high up in the sky, it gets extremely cold. Much colder than your fridge. Much colder than outside today even.
Koko:
Whoa. That is really, really cold then.
Owlo:
When it gets that cold, those tiny water drops freeze. Freezing means they turn from liquid water into something solid.
Koko:
Like when Mom puts juice in the freezer and it turns into an ice pop!
Owlo:
Exactly like that! You are so smart, Koko. When the drops freeze up in the cloud, they turn into tiny ice crystals.
Koko:
What is a crystal?
Owlo:
A crystal is a solid shape with flat sides and sharp edges. Ice crystals are very small and have six sides, like a tiny star.
Koko:
Six sides? Like a star? That sounds really pretty.
Owlo:
They are beautiful. And here is the magical part. Many tiny ice crystals stick together to make one snowflake.
Koko:
So a snowflake is actually lots of tiny ice stars all stuck together?
Owlo:
I love how you described that. Yes, tiny ice stars stuck together is a wonderful way to think about it.
Koko:
And then the snowflake falls down because it gets too heavy for the cloud to hold?
Owlo:
That is exactly right. When the snowflake gets big enough and heavy enough, it floats gently down to the ground.
Koko:
That is why it falls so slowly! It is like it is dancing on the way down.
Owlo:
What a lovely way to see it, Koko. Every snowflake dances its own little path all the way from the cloud to the ground.
Koko:
And no two snowflakes look the same, right? I think I heard that somewhere before.
Owlo:
You heard correctly. Because the crystals stick together in different ways every single time, every snowflake is unique.
Koko:
Just like how every fox has a different tail pattern. Mom told me that once.
Owlo:
That is a beautiful connection, Koko. Now, before you head back out into the snow, can you tell me what you learned today?
Koko:
Okay! So, clouds are made of tiny water drops. When it gets super cold up in the sky, the drops freeze into tiny ice crystals with six sides, like little stars.
Koko:
Then the crystals stick together to make a snowflake. When the snowflake gets heavy enough, it dances all the way down to the ground. And every single snowflake is different, just like me!
Owlo:
Perfect, Koko. You explained that beautifully. Now go enjoy the snow, and maybe next time we can learn why the sky turns grey before it snows.
Koko:
Oh yes! And maybe why my breath makes little clouds when it is cold! There is so much to find out!
