What have we learned from our evaporation

investigations?

What happened to the water molecules?

How can you speed up the process?

What is the Science of rain?

Find out about the

science of rain by

watching these 3

LO: I understand that water constantly moves in a cycle. I can

identify where condensation and evaporation occur in the water

cycle.

Task A:

Your task today is to draw a diagram of the water cycle.

Use arrows like those labelled on the next slide to show the

movement of water molecules.

Arrows to show

LO: I understand that water constantly moves in a cycle. I can

identify where condensation and evaporation occur in the water

cycle.

Task B:

Explain the science in the water cycle.

Show where the processes of condensation, evaporation and

precipitation take place.

Write an explanation of what happens to the water molecules

during the different processes. Remember to include the words:

molecules, solid, liquids, gas, heat, energy in your explanation.

You can look back at the earlier videos or use this song to

help you remember the different stages in the water cycle.

Look at the picture.

Look closely at the inside of the bag!

What do you think is happening?

Task C

That’s right there is

condensation on the

inside of the bag.

Where are the water molecules

coming from?

Task C

Right again, they are

coming from the leaves

of the plants.

The water molecules

escape from the leaves

into the atmosphere.

This process is called

transpiration.

It adds more water to

the water cycle.

Task C

Add transpiration to

your diagram!

Task C

Look at the picture.

What do you think is happening and why?
