Lesson: 02
Suggested Duration: 4 days
1. Prepare the Water Cycle Model as indicated on the Teacher Resource: Water Cycle Model. Set up the demonstration of the water
cycle. It should be in a location where students can see the model. You will need a heat lamp (the Sun), a heat-proof bowl that is
clear, really hot water that is colored blue (make sure the water does not melt the container if using a plastic container), plastic wrap,
and several (5-6) ice cubes. Pour the really hot colored water in the container. Quickly cover the top of the container with the plastic
wrap, pulling the plastic tightly and sealing the edges. Turn on the heat lamp so it is shining on the water through the container. You
will place the ice cubes on top of the plastic just before students are observing the model.
2. Print the Teacher Resource: Each One Teach One: The Water Cycle. Cut out each statement. Use the top set to distribute to the
student groups. The second set could be taped to the chart paper so that both the statement and the student responses will be
shown.
3. Prepare attachment(s) as necessary.
Background Information
This lesson looks at the continuous cycling of water on the Earth’s surface and the role the Sun plays in this cycle During this lesson, students will also extend
their exploration of the water cycle with a greater emphasis on its movement on and above the Earth.
It is important to note that the standard in this lesson is a Supporting Standard. Not only might the content in this lesson be assessed on STAAR, it is most
certainly foundational for Supporting and Readiness Standards at Grade 5.

in lieu of the Teacher Resource: Water
Cycle. http://www.epa.gov/safewater/kids/flash/flash_watercycle.html
7. Distribute the Handout: Water Cycle Captions and a plain sheet of
paper to students. Read each of the captions to the class.
8. Instruct students to draw a model of the water cycle on the paper. The
diagram should be labeled with the science terms: accumulation,
condensation, evaporation, and precipitation. In addition, the diagram
should have color. The captions should be cut apart and then placed in
the appropriate location on the diagram.
When students are constructing their own conceptual model of the
water cycle, it is up to the teacher whether or not to leave the Teacher
Resource: Water Cycle projected. Conceptual Model: a type of
diagram that defines a concept or shows a relationship within a
system.
9. When students have completed the conceptual model (diagram), they
should affix it in their science notebook as a reference during the lesson.
Safety Note:
Students should follow safety protocols when working with sharp
instruments.

EXPLORE – Water Cycle Model
Suggested Days 1 (continued) and 2
1. Set up the water cycle demonstration as shown on the Teacher Resource:
Water Cycle Model. Prepare the demonstration before the lesson starts to
ensure a clearer model of the cycle.
2. Inform students that observations will be recorded in their science notebooks.
3. Say:
You are going to observe another model of the water cycle.
You will draw and label the model in your science notebooks.
In addition, as you observe the water cycle model, add the correct
terms (accumulation, evaporation, precipitation, and condensation)
to your diagram.
Materials:
container (heat-proof, clear, about a 2 quart
capacity, 1 per teacher)
water (colored blue, hot, 1 cup per teacher)
plastic wrap (about 12”x12”, 1 piece per
teacher)
heat lamp (goose neck, 1 per teacher)
ice cubes (5–6 per teacher)
index card (3”x5”, 1 per student)
scissors (1 pair per student)
glue (liquid or stick, 1 container per pair)
4. Allow time for students to come up to observe the water cycle model. You may
prefer to have students come up in small groups to observe. If small group
observation is preferred, then distribute the Handout: Water Cycle Cards and Attachments:
instruct students to begin matching the terms with the pictures.

student)
6. After all students have had the opportunity to observe the physical model of
the water cycle, facilitate a class discussion using the following guiding
questions:
Instructional Notes:
What represented the Sun in this model? (The lamp)
What caused the water to evaporate? The heat from the lamp heating
the water
What role does temperature play in the water cycle? The heat energy
from the Sun is what causes the water to evaporate. The cooling of the
water vapor causes condensation.
In what ways does the Sun play a role in the water cycle? The Sun
heats the land and water. The water often evaporates. The heating and
cooling of the land creates the wind. Wind moves the clouds to different
areas.
What caused the evaporated water to condense? The water vapor
cooled down because of the ice. The droplets condensed.
Does all precipitation stay on the surface of the Earth? (No)
In what other locations on Earth is water found? Water is stored in
plants and soil. Additionally, water seeps into the ground and it may
become a part of the water that is stored below the Earth’s surface called
an aquifer.
Discuss the fact that this is a model and not exactly how it
happens in nature every time. It just helps us to visualize the
process. Limitations of models should always be addressed
when using a model.
It is critical for the teacher to reinforce the idea that the Sun is
the primary source that drives the water cycle.
Students may think that there is a beginning and an end to the
water cycle, instead of recognizing that water moves
continuously above and below the Earth’s surface.
Check For Understanding:
The summary can be used as a formative assessment of
student understanding.
7. Distribute an index card to each student. Students should write or draw a
summary of what they learned today about the water cycle.
EXPLAIN – Comparing Water Cycle Models
Suggested Day 2 (continued)
1. Distribute the Handout: Water Cycle Cards (if students did not receive them
yesterday).
Attachments:
2. Instruct students to match the concept with the picture. You may wish to check
the matches before students affix them in their science notebooks.
3. Review what students observed during the demonstration. Reinforce the
concept that the Sun is the primary energy source for the water cycle.

cycle?
Materials:

colored pencils (1 pack per pair of students)
Attachments:
3. Distribute the Optional Handout: A Writing Connection. Instruct students to
answer the three questions using pictures and words.
4. An alternative way to complete the writing connection is to distribute a piece of
paper to each student. Instruct them to fold the paper in fourths to create a
small booklet. Project the following three questions:
Teacher Resource: PowerPoint: The Sun’s
Role in the Water Cycle

Water Cycle Captions
Use the following captions to help you with the components of the water cycle model:
precipitation, accumulation, condensation, and evaporation. Make sure you use color
illustrations in addition to the captions.
Water falls to the Earth, from the clouds, as
precipitation. It collects in lakes, ponds, and
oceans. Some precipitation seeps into the
ground, and some precipitation flows along the
land into bodies of water.
The Sun’s energy heats the water and causes
it to evaporate and become water vapor.
The water vapor rises
into the air.
Warm winds carry the
water vapor higher
into the sky.
In the sky, the water
vapor cools and condenses on atmospheric
particles into tiny droplets of water
to form clouds.
When the water droplets
become heavy enough,
they fall back to Earth
as precipitation.

Cut out the cards. Read the statement on each card, and then match the card with the corresponding picture. You may check with a partner
to verify that your matches are correct. Glue the matching pairs onto a plain piece of paper or directly into your science notebook.

An aquifer is an underground layer of
water that moves through porous rock.
It is not an underground river. The
water moves through the spaces of
porous rocks such as limestone,
sandstone, and some fractured
volcanic rock.
Water condenses around dust
particles to form clouds. There are
hundreds of water droplets in each
drop of water.
Water vapor evaporates back into the
atmosphere. Evaporation is when
liquid water changes state to a gas, or
vapor. Evaporation is the main way
that water moves back into the water
cycle.
Water sometimes seeps into the soil
and is stored as groundwater.
Most water on Earth is stored in the
oceans.
Water accumulates in streams, rivers,
ponds, lakes, and oceans.
Clouds release water back to Earth
through precipitation in the form of
rain, snow, sleet, or hail.
The Earth’s water is always in motion.
The Sun’s energy drives the water
cycle and creates wind.
