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.
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.
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?
Did you say . . .
Yes! Water is what they have in common!
Write 2 or 3
these things use
and need water
to function or
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 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
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
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.
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.
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?
This picture you have just learned about is called a WATER CYCLE

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.
