The Professor’s Lesson
Hello, I’m Professor Dew
Today we’re going to talk about something called The Water Cycle
Where are those students?
Oh, here they come now!
Hey everyone, who wants to go on a field trip?
Okay, grab a buddy and let’s go!
The first thing we’re going to learn about is condensation.
Condensation is when water vapor in the air is changed into liquid water.
Look, here’s some water vapor now.
Vapor is the gaseous form of water.
Water has three states: vapor is the gaseous form, water is the liquid form and ice is the solid form.
As the air cools down, the water vapor starts to get closer together and turn into drops just like us!
We’re all turning into a rain cloud!
When the air is really cold...
I know! It starts snowing!
Water will freeze and…does anybody know what happens?
That’s correct, it freezes and falls as snow
And when the air is warm...
Does anybody know this one?
Ooh, I know this one!
We fall as rain!
Does anybody know another word for raining or snowing?
Whoah! We’re raining!
We’re getting close to the ground
Prepare for landing!
That’s better. We’re safe and sound in the ground
Look at that plant
When rain falls on the ground, some of it is absorbed by plant roots
The water is drawn up the plant’s stems and to its leaves
When the plant is done with the water, it turns back into water vapor
This is called transpiration
Is this going to happen to us?
It is part of the water cycle
But today we’re going to keep the group together
We’re in the Top Soil
Top soil contains moisture and many organisms like plant roots, insects, and small animals
Now we’re in the Sub Soil
The Sub Soil contains more rocks and is more compact than Top Soil, and filters contaminations out of water
You mean the dirt cleans the water?
As funny as it sounds, yes, it’s called Filtration. It doesn’t get us perfectly clean but it helps.
Below us are even more layers, the Sub Stratum, Deep Groundwater, and Bedrock
But we’re going to stay in the Shallow Groundwater
Ground Water is fresh water found anywhere in the spaces between ground layers
When a lot of water collects porous rock underground, it’s called an aquifer
Aquifers supply man-made wells with drinking water
When an aquifer gets full of runoff water, it can create a natural well, which helps replenish lakes
Here we go!
We’re about to leave the aquifer and go into the lake
Here we are at the surface of the lake!
The sun is warming up the surface, get ready to evaporate!
Back to class we go!
I hope everyone had fun learning about the water cycle today
Time for me to go home too
Look, those water drops are becoming surface runoff
The water will stay on the ground until it ends up in a stream, river, or lake
