The
water cycle - student activity
|
Victorian Essential Learning Standards Domains and (Levels):
Science (3,4)
Duration: Preparation time - 90 minutes, Activity
time - 50 minutes.
Setting: A large room or playing field.
|
Summary:
With rolls of the dice, students simulate the movement of water
through the water cycle.
Objectives:
Students will develop an understanding of the movement of water
within the water cycle and identify the different states of water
as it moves through the cycle. Upper level students will identify
and describe the processes associated with the changed states of
water.

Connections:
The water cycle is often presented simply as water in a stream flowing
to the ocean, evaporating to the clouds, raining down on a mountain, and
flowing back down the stream. Role playing a water molecule will help
students understand the water cycle as more than a two dimensional path.
The
Activity
Introduction:
Ask students to identify the different places water can go as it moves
through and around the Earth.
Write the responses on the board. Discuss the conditions that cause water
to move. Sort and categorise the responses into groups similar to those
listed in Step 1 below; OR give students the headings and ask them to
sort their responses. Discuss the different places water can go from each
of the stations.
Procedural
Steps:
| 1. |
From
discussion, list nine stations water can move through. (eg, Clouds,
Plants, Ocean, Animals, Rivers, Lakes, Ground water, Soil, Snow &
Ice) |
| 2. |
Write
the names of the selected stations on the A3 paper and place them
around the room where they are easily seen and well-spaced, creating
nine stations. |
| 3. |
Tell
students that they are water molecules moving through the water cycle. |
| 4. |
Assign
students to each station, making sure they are well spread. |
| 5. |
Hand
each student a water cycle worksheet. |
| 6. |
At each
station, students can discuss where and in what form water moves from
that place to another. |
| 7. |
Give
one dice to each station. (Groups can check against the dice to see
if they have identified all the places water can go from their station) |
| 8. |
Students
are to line up behind the dice at their stations. |
| 9. |
Each
student rolls the dice and moves to the location indicated by the
label facing up. If they roll "stay" they move to the back
of the line. When students arrive at the next station they should
move to the back of the line. |
| 10. |
Students
are to keep track of their movements by drawing lines on their water
cycle worksheet to show where they have been. |
The game
will begin and end with a whistle or other sound.
Discussion
& Wrap Up:
| » |
Discuss
any cycling that took place. |
| » |
Ask
students to suggest reasons for the results represented on their worksheets. |
| » |
Discuss
where evaporation, condensation, precipitation, transpiration would
occur. |
| » |
Discuss
the state water would be in at different stations. Identify other
points in the natural processes where that state occurs. |
| » |
Provide
students with a location, eg. small stream, car park, dam, wetland,
well, etc and have them identify ways water can move to and from that
site. |
| » |
Discuss
the role of humans in the water cycle. What are the impacts of human
activities? |
| » |
Have
students write stories about their journeys as water molecules: eg.
the places they have been and the conditions necessary for them to
move on. |
Extension:
| » |
Have
students compare the movement of water at different locations and
during different seasons. |
| » |
Investigate
how water can be polluted and cleaned as it moves through the water
cycle. |
| » |
Use
the extension and discussion points as the basis for group learning
projects which can later be shared with the whole class. |
Assessment:
| » |
Test
students' understanding using another copy of the worksheet. Ask them
to identify the state water is in as it moves between specified stations,
the processes involved in that movement, where movement cannot occur.
|
| » |
Students
can explain what they have learned using diagrams and/or writing a
story. |

To
make the dice for the stations:
| 1. |
Use
9 cubes with approx. 15cm sides (Students could make them in Maths) |
| 2. |
Create
one dice per station using the linked stations table as a guide
for the appropriate number of pictures for each dice. You will need
the following pictures:
| Animals
= 3 |
River
= 5 |
Groundwater
= 5 |
| Clouds
= 13 |
Plants=1 |
Soil
= 3 |
| Lake
= 4 |
Ocean
= 3 |
Snow
& Ice = 1 |
| Stay
= 16 |
|
|
|
| 3. |
Photocopy
the student worksheet and cut out the required images OR use student
drawings. |
