Where Does Water Come From: The Water Cycle
Learners develop an understanding of the water cycle. They will then use this knowledge to create a tactile model of the water cycle and then relate these ideas to the importance of water conservation.
The learner will:
- discuss the water cycle.
- identify key components of the water cycle.
- state why water conservation is important in relation to the water cycle.
- demonstrate an understanding that water conservation is an act of stewardship for the Earth.

- Process Signs: Condensation, Evaporation and Precipitation (Handout One)
- Water Cycle Handout (Handout Two); one for the teacher and one for each child
- Water Cycle Cut-outs (Handout Three); copy on cardstock one for each child
- Water Cycle arrows (Handout Four); one copy for large diagram

- Sand and grass clippings (optional)
- Cotton balls (Stretch out the cotton ball to form “clouds”)
- Crayons/colored pencils/markers
- White glue
- Masking tape
See the lesson adaptation at the bottom of the page. There is a fun suggestion from a teacher to help the students practice the concepts.

Day One Anticipatory Set: Ask learners if they have ever seen rain. Another word for rain is precipitation. Where does rain come from? How does it get into the cloud? We are going to listen to a story about the Water Cycle. Listen and hear what this story tells us about water and how it moves.
Read The Magic School Bus Wet All Over: A Book About The Water Cycle. While reading be sure to emphasize “condensation” “evaporation” and “precipitation”. These are the major points in the water cycle.
When the story is finished, ask learners to recall the three steps water goes through (evaporation, condensation and precipitation) and what they are. Use the process signs provided (see Handout One). You may choose to post these where the students can see them during the discussion.
Show learners the water cycle handout (see Handout Two) and touch each area on the picture map. This will help them see what is exactly necessary for each of the three steps.
Tell learners that together the class will be creating a very large water cycle model. They are each going to make a portion of the water cycle. Teacher Note: It will be necessary for the teacher to decide if each learner will make each piece of the water cycle or if learners will be arranged into groups to work on the water cycle.
Distribute Water Cycle cut outs (see Handout Three). The learners do the following:
- Color raindrops blue and cut them out.
- Cut out clouds and fill them in using white glue and stretched cotton balls.
- Cut out blue construction paper to look like water.
- Cut out brown construction paper to look like land (optional: decorate using sand and grass attached with white glue).
- Cut out yellow construction paper to look like the sun.
When all pieces have been constructed, set aside to dry.
Review the terms: condensation, evaporation and precipitation.
Ask learners to recall the three major parts of the water cycle and the conditions for each to take place. Be prepared to reference The Magic School Bus Wet All Over: A Book About The Water Cycle
Distribute the water cycle handout (Handout Two) to each child. Review each of the components and invite them to add color. Assemble the pieces to the large water cycle by allowing the learners to place their pieces on the diagram. Invite learners to use their handouts as a guide.
Add the directional arrows to complete the diagram (see Handout Four).
Tell learners that the water moving about in the water cycle does not fall exactly where it evaporated from. Some places receive more and some receive less rainfall. Each place has different needs for its water. The area may not receive enough precipitation in the form of rainfall and that can be a problem. That is why it is SO important to conserve water.
Who needs to conserve water? – Everyone!
Explain to the learners that they can also help their friends and families conserve water by sharing what they have learned about water.
The teacher should observe the learners’ participation in group discussions, construction and assembly of their water cycle.
