2.2. WATER, WATER EVERYWHERE
(Level: 2 : 5 :: Water Cycle)
Purpose: To illustrate a simplified water cycle.
What You Need: markers and/or crayons :: glue sticks ::
scissors :: construction paper :: water cycle worksheet :: water
cycle stencil pieces :: water cycle layout (for personal
What You Do:
- Photocopy water cycle worksheet for each student.
- Prepare your own colourful, enlarged pieces (use photocopier
to enlarge) from the water cycle stencil to attach to the
blackboard as you teach the lesson.
- Begin by asking the students to name the many different
places that water can be found (in lakes, rivers, oceans,
wetlands, ice, rain, etc.). Write these words on the
- Explain that water moves around the earth in many different
forms (solid, liquid, and gas). Water flows through streams,
wetlands, rivers, and lakes, often returning to the ocean. But,
where does the water that is in the rivers and streams come from?
(from rain, snow and other precipitation) - and they fell out of
the sky from a cloud. But, where did the water in the cloud come
from? (from vapour).
- Begin to explain the water cycle, starting from the oceans,
using the sun, heat, and ocean stencil pieces. A simple analogy
to explain the process of evaporation is a kettle. Water and heat
goes in, and steam comes out. Explain that the hot sun warms the
water in the ocean and the ocean water becomes steam. Attach the
sun, heat, and ocean pieces to the blackboard following the water
- Continue to explain the water cycle using the cloud, rain,
and land pieces. Ask the students where the rain comes from
(attach the cloud to the blackboard) and where rain goes (into
the land, streams, wetlands, and used by plants). Attach the
cloud, rain, and land pieces to the blackboard.
- Explain that when it rains, water runs over the land into
streams. These streams flow into wetlands which may drain into
lakes and rivers. Finally, these rivers may run into the ocean to
start the whole process over again. Attach the stream, wetlands,
lake, and river pieces and draw the last loop of the circle back
to the ocean.
- Explain the water cycle one more time, emphasizing that it is
a continuous process, and explain what happens between each step
of the cycle. You may wish to ask a student to come up to the
blackboard to explain a part of the water cycle to the rest of
the class, or have the students repeat the process out loud with
- Have the students colour the water cycle worksheet and then
cut out each component of the worksheet. Each student can then
arrange and glue their water cycle pieces on the construction
paper, drawing arrows and labelling each piece.
- Ask the students to draw and colour one place where water is
found (on one side of the sheet of paper), and one way water is
used (on the other side of the sheet of paper).
- Older students may want to discuss the water cycle adding the
component of pollution. For example, if certain chemicals are
released into the air, they can combine with water in the clouds
to form acid rain. If water is polluted, it may easily flow and
pollute other bodies of water. Unit 5: Environmental Issues, will
provide helpful background information for this discussion.
