Step 2: “Miss Droppy’s journey”: an interactive story
Objective: to learn lexis about the water cycle
Activities: 1. draw the story (flashcards or big book)
2. storytelling – drama
The teacher tells the story of “Miss Droppy and Mr Tree”.
There are many ways to tell a story. The teacher chooses the way that he/she prefers.
The story can be accompanied by teacher explanations of words, through pictures, acting out
meaning or verbal explanation.
Activity 1:
The pupils draw the pictures of each scene of the story. The teacher collects these pictures in
a big book.
The teacher can also use these pictures to do a multimedia work (on CD) on the computer.
Using a multimedia software the pupils, after acting the story, can record their voice. Each
“actors’ group” will have a different Cd rom.
Activity 2:
The pupils can act the story. Each group of pupils can personalize its playing, for example
making masks to wear during the acting,

STEP 3: “H₂O: Who am I?”
Objective: to know the water molecular
structure
Activity: Water molecule game:
Brainstorming “WHAT DO YOU
THINK IT IS?”
The teacher shows a model of water molecule (see the picture below). The model is made of 3 balloons: one is light blue (the oxygen
atom) and two are white (hydrogen atoms).
The teacher can also use a picture of a model made of three circles of cardboard. In that case, during step 2, the teacher gives out the
cardboard circles to the pupils to make some badges.
The teacher asks: “What do you think that is?”
After the discussion, the teacher helps the students to find out the right answer:
“It’s a water molecule.
It is made of 2 “balloons” (atoms) of hydrogen and 1 “balloon” (atom) of oxygen.
You can find lots and lots of water molecules in a bottle of water”
Water molecule game: “HOW MANY WATER MOLECULES CAN YOU FIND IN OUR CLASSROOM?”
The teacher gives each student a balloon (or a cardboard circle to make a badge).
The teacher has to hand out the right number of “oxygen balloons” and “hydrogen balloons”. Each pupil has got a balloon and
has to join other classmates to make a water molecule. The balloons can be glued together.
The teacher asks each pupil: “WHAT’S YOUR NAME?”
The pupils say: “MY NAME IS HYDROGEN”… ”MY NAME IS OXYGEN”
The teacher asks: “WHO ARE YOU?”
The pupils answer: “WE ARE A WATER MOLECULE”

STEP 4: “Where are you from?”
Objective: to know the water cycle
Activities: Match and colour
Label the pictures
Cut and stick the labels
Put the sentences in the right order
Word album: the names of the environments where you can find water
During the previous lesson, the teacher invites the pupils to cut out from magazines,
newspapers, etc. pictures of environments where you can find water
(ex. sea, pond, lake, river) and to bring them to school.
Then , the teacher collects the pictures of different environments to make a wall poster and say the names:
“This is the sea……….. This is the river….”
Then pupils repeat the names and label the pictures on the wall poster.
The teacher checks the pupils’ comprehension; they have to do the activity “match and colour”.
Explanation of water cycle “Where do you come and go?”
The teacher explains the water cycle:
Water, heated up by the sun, evaporates into the atmosphere from lakes, sea, ocean, ……….
The water vapour goes up into the sky. The sky is cool and the vapour condenses. It forms clouds.
The wind blows and moves the clouds.
When the clouds meet cool air, the little drops become big and heavy: the rain falls down.
The rain goes into the rivers, lakes and finally goes back to the sea………… and the journey starts again.
While the teacher speaks, he can show a picture (as it is shown in file “ stick label 1”) or
he can draw the water cycle on the blackboard / wall poster.
After the explanation, the pupils do the activities (Label the pictures, Cut and stick the labels, Put the sentences in the right order ).
The teacher decides if the pupils can work alone or in pairs. The teacher can lead the work if the pupils are very young.
The activities are useful both as consolidation works and tests.

THE VAPOUR CONDENSES. IT FORMS CLOUDS.
3) THE WIND BLOWS AND MOVES THE CLOUDS.
4)THE CLOUDS MEET COOL AIR.THE LITTLE DROPS BECOME BIG AND HEAVY AND THE RAIN,
THE SNOW OR THE HAIL FALL DOWN.
5) THE RAIN GOES INTO STREAMS AND RIVERS. FINALLY IT GOES BACK TO LAKES
AND SEAS AND … THE WATER JOURNEY STARTS AGAIN.

Step 5: “Am I solid, liquid or gas?”
Objective: learning about the water states
Activity: Read and fill in the pictures (Number the pictures)
The teacher explains that the water can change its shape.
This happens because the temperature can change the “position” of the molecules in a drop of water:
1.
The water can be liquid and it can have the shape of the container. The water molecules are close
to each other but they can move.
2. The water can be solid. It freezes when it reaches a temperature under 0° C. It can turn into an
ice-cub. The water molecules are very close to each other; they can’t move.
3. The water becomes a vapour when it’s boiling and it reaches 100° C. The water molecules can move
in every direction.
During the explanation, the teacher can show or give the pupils the form “water states” (see file water
states).
Then the pupils have to read and number the right picture on the second form (see file number
pictures). This form can
be useful as activity
or to check the pupils’ comprehension of the contents of step 5.

“Look at me! I’m magic… I can change shape.”
1) I can be LIQUID
…and take the shape of the container.
2) I can be SOLID
…I freeze, I can turn into an ice-cube.
3) I can be a GAS
…I become a vapour when I’m boiling and I reach 100°C.

Step 6: The atmosphere
Objectives: 1. knowing the layers of the atmosphere (year 8-11 students)
2. knowing about the atmospheric phenomena
Activities: Listen and complete
Read and draw
Read and match (year 8-11 students)
The teacher explains that the meteorologists (the scientists that study the sky, clouds, rain, etc.) divide imaginatively the sky
in zones. The atmospheric phenomena go on in only one part of the sky called troposphere.
If the students are 8 – 11 years old, the teacher explains the layers of the atmosphere, using the form
in file “atmosphere” and the pupils have to complete the scheme (see file “ layers”).
This part will probably require some Italian in the explanation too; if it is possible this lesson
can be expounded altogether with the science-teacher.
If the students are younger, the teacher explains only the atmospheric phenomena.
We have attached an exemplification (see file “atmo phenomena”) of what the teacher can say.
The older students can complete all the activities.
The younger students can do the “Listen and complete” and the “Read and draw”.

The atmosphere is the air that surrounds the Earth. It is composed of nitrogen (78%), oxygen (21%), carbon dioxide,
water vapour and other gases.
Carbon dioxide in big quantity is poisonous for humans. It comes from transpiration (people, animals, plants…) and from
some burning materials (wood, oil, coal).
In the air there are also very little particles of dust: atmospheric dust.
The atmosphere is about 300 miles (480 km) thick.
THE LAYERS OF THE ATMOSPHERE
THERMOSPHERE.
It includes the exosphere and part of the ionosphere.
Temperature increases with altitude.
EXOSPHERE.
It is the highest layer.
It goes from about 400 miles (640 km) to about 800 miles (1280 km).
IONOSPHERE.
It starts at 43-50 miles (70-80 km) and continues to 400 miles=640 km.
MESOSPHERE.
It is between 31 and 50 miles (50-80 km).
Temperature decreases with altitude.
STRATOSPHERE.
It is between 11 and 31 miles (17-50 km).
Temperature increases with altitude.
In the stratosphere there is the ozone → a type of oxygen very important for our survival. The ozone absorbs a lot of
ultraviolet radiation
TROPOSPHERE.
It is the lower layer.
It goes from ground level to 11 miles (17 km) high.
Temperature decreases with altitude.

The science of weather is called METEOROLOGY, from the Greek word ‘meteoron’ → talk about the sky.
The weather develops in the TROPOSPHERE.
●
WIND
A layer of air, heated by the Sun’s rays, goes up.
Cool air comes down and takes its place.
●
CLOUDS
Clouds form when warm air meets cold air.
A cloud is made of lots of drops.
●
RAIN
When the drops in the clouds become heavy they fall…
●
THUNDER
and
LIGHTNING
When dark clouds bump…they produce an electricity. This makes a bright light
called lightning. The thunder is the noise you can hear.
●
SNOW
When clouds meet very cold air, the drops become crystals of ice and form
snowflakes.
●
HAIL
Sometimes in the clouds there are frozen drops. They become little ice-cubes →
hailstones and fall…
●
WEATHER FORECAST
Meteorologists make forecasts by studying information that comes from instruments on planes-ships-satellites…
