(Strand VI-B6)

Activity:

Procedure:1. The teacher will click through each of the slides, reading the

instructions to the students.

2.Each slide is self-explanatory, but the teacher should run through the lesson prior to presenting it to the students.

Related Activity:

Each lesson is followed by a journal activity of some kind. There is also a fun cut & color activity at the end of the presentation.

Lessons:

1. Water-Exists as a Gas, aLiquid or a Solid on the Earth

2. Water-Condenses & Evaporates (Water Cycle)

What do these things have in common?

Canyou

figureit

out?

Did you say . . .

WATER?

Yes! Water is what they have in common!

Journal:

Write 2 or 3

sentences why

these things use

and need water

to function or

work.

Does water always stay a liquid?

Look at this picture and write about where you see water as a

liquid and where you see water as

NOT a liquid.

Did you find these 2 areas where water was a liquid in this picture?

These areas of water are BOTH

liquid, but there is a difference

between these 2 liquid waters. Can you you see the

difference between them. Make a guess in your

journal.

If you said these areas are

different because one is falling and one is just sitting there, then you

would be CORRECT! Which

one is falling?

Yes! This water is falling.

It is falling because it is rain and rain is water that falls from the sky called . . .

PRECIPITATION.

PRECIPITATION comes in many forms.

Can you name some of the forms you see here?

Did you say RAIN and SNOW?

Help your teacher choose the pictures that show RAIN or

SNOW.

Teacher, bring your arrow to the bottom left-hand corner. You should see an arrow appear. Click on this arrow and choose pen. Use this pen to circle your students’ guesses. Just click and drag your mouse to make a circle around your choice. When you are finished using the pen, go back to the corner arrow, click, and choose arrow to go on with this presentation.

PRECIPITATION happens as a part of a CYCLE. It is just one part of this CYCLE that shows us water as a liquid, as a gas, and sometimes as a solid.

Liquid Gas Solid

Let’s talk about the first part of that CYCLE.

Find the area of water that is NOT liquid.

Can you locate this area?

Teacher: you can use the pen again to circle your students’ choices.

Did you choose this area as your NOT liquid water?

Journal: Make a

guess. What type

of water is this

if it is not a

liquid? I’ll give

you hint. This

water is going

up!

This type of water that is NOT a liquid is called a GAS. This type or form of water is

made by EVAPORATION.

PRECIPITATION and EVAPORATION work together. They act as a team.

EVAPORATION takes liquid water from the earth, adds heat to it & changes

the liquid water to water as a GAS or a VAPOR.

Where does that heat come from?

I’ll give you just a tiny little hint.

It’s very bright and keeps us

warm.

Was this your guess?

When that heat is added to the earth’s water, such as in a lake.

It changes that liquid water to water as a gas. As a GAS that water goes up into the clouds.

Water as a GAS can

also evaporate because of

WIND.

Once that water as a GAS goes up into the sky, the only place it has to go is

DOWN.

Let’s talk about the

second part of that CYCLE.

When that water as a GAS is up in the clouds it begins to get COLD. As

it gets COLD it gets HEAVY.

That adding of COLD air to the water as a GAS is called CONDENSATION.

JOURNAL:

Why does the water as a gas get cold up in the clouds?

Because the farther up you go, the colder the air gets.

So now, we have some very COLD and very HEAVY water as a GAS. What do

you think is going to happen?

Hint: It’s got to come down!

JOURNAL: What will it look like when it comes down?

Draw a picture of what you think it will look like when it

comes down. Just a small hint. Remember the word

PRECIPITATION?

Let’s talk about the

third part of that CYCLE.

Do your pictures look like any of these pictures?

REMEMBER the many forms of PRECIPITATION?

Circle the forms.

Can you name each

form?

Let’s think about what we have just learned.

JOURNAL:1. What forms can water have?2. What makes water evaporate?3. What is Condensation?4. Why do we get rain & snow?

Take a look at this picture. This picture

shows all the parts of the

CYCLE we have just learned

about.

This picture labels EVAPORATION, but does not label PRECIPITATION & CONDENSATION.

Use the pen to circle those areas of CONDENSATION and PRECIPITATION.

Are these the areas you circled?

GREAT!

This picture you have

just learned about is called a WATER CYCLE

Teachers:

The next two (2) pages are part of an activity to make your very own WATER CYCLE. Please import and print them for your students.

Students may cut and color their own personal WATER CYCLE.
