The Water cycle

Before we get rolling into the water cycle, let´s learn about the water.

What is water?  

Water is always changing,
      Water is always moving,
                Water is everywhere.

Water can be liquid, for example, the river water.
Water can be solid, for example, snow.
Water can be gas, for example, vapor.

Water has no taste, no color and no smell.

Did you say water is always moving? 
Well, this is what we know as water cycle.



What is the water cycle?

The sun shines and heats the water and turns it into vapor.
This is called evaporation.

When the vapor cools downit becomes a cloud of tiny droplets.
This is called condensation.

Water droplets bang together and get big falling to the
land into rain, snow or hail.
This is called precipitation.

Water moves from the land to the sea, lakes and river.
This is called collection.


Now the water cycle begins again.





Time to play
