Outcome

Rain
EAH REV 2/11/2019
What does it mean when the meteorologist says we received 1 inch of rain? It means that enough rain fell to cover the entire area 1
inch deep, if the water fell straight down and stayed there.
The intensity of the rain also indicates whether or not flooding occurs.

Make a Floodplain Using the materials your teacher has provided, create a floodplain.
Be sure to include a river in your project (it can be straight or curvy)
Start with a natural landscape
Record your observations
Change the landscape to create an urbanized landscape and record your observations
Work with your team to find solutions to help control the flooding
Complete the VENN Diagram to compare and contrast what happens in an urbanized area compared to a natural landscape

Your Emergency Plan Homework for next time: Know your address Memorize important phone numbers Have a list of other adults you can talk to or wait with, if
you can’t reach your parents or guardians right away. Choose a place that you and your
family will meet if you aren’t ableto make it home.

IT’S RAINING, IT’S POURING, IT’S FLOODING IN MARICOPA COUNTY! LESSON 3
• It’s Raining, It’s Pouring, It’s Flooding in Maricopa County! Power Point
• Chart Paper/Markers
• Key Vocabulary
• Aluminum baking pan (can be disposable kind)
• Small plastic storage bin (1 for each group)
• Modeling clay
• Math cubes (to represent buildings)
• Water supply
• Engineering Planning Sheet
Teacher Prep
Materials
Activities
1. Review vocabulary terms using TPR 2. Model the online Interactive Flood Simulation at apps.fcd.maricopa.gov/ifs/ifs.html 3. Show Flooding Videos 4. Students create a floodplain
• Use the modeling clay to simulate the earth • Form rivers in the clay • Students place buildings, animals, etc. in their model • Pour water in the top of the river to see what happens • Record observations • Create an urban landscape and repeat process • Create solutions to solve the flooding problem
5. Complete VENN diagram to compare and contrast water flow in an urban environment and natural environment
• Download It’s Raining, Its Pouring, It’s Flooding in Maricopa County! Power Point
• Gather materials for students to create flood simulations
• Preview key vocabulary

Extension Go to https://www.maricopa.gov/3847/Flood-Control-District Under the citizens tab, click on Floodplains map. Have students enter their address in the search box to see if they live in a floodplain. Students then research ways in which their community has responded to flooding in the past. Has it been effective? Why or why not?
Lesson 3: Why Does it Flood?

How does Urbanization Affect Flooding?
Test 1. The pan will be used as your base. 2. You may cut off the end of your pan
so that water can flow out. If you do this, use the tub to catch the water.
3. The modeling clay is your ground. Be sure to create a river.
4. Make a prediction of what will happen after urbanization.
5. Pour water at the top of your river and record your observation.
6. Create an urbanized landscape, add houses, roads, sidewalks, parking lots, etc.
7. Pour water at the top of your river and record observations.
8. Construct various ways to control the flow of water.
Hypothesis (What do I think will happen?)
Observation (What did I see? You can draw and
describe.)
Conclusion (Was my hypothesis correct? How
do I know?)
Lesson 3: Why Does it Flood? What did you and your team do in order to help control the
flooding? Did you create levees, dams, or culverts? Did it work? Explain why you think it did or did not work.

Environment
Make a Floodplain Model Background Information A floodplain is the dry land surrounding a river or stream. When enough
rain falls, the river may fill beyond its capacity, wiping out structures in its path. When this happens, the buildings and structures in the floodplain could be washed away.
Purpose
Students will design ways to keep flowing water from damaging structures in the floodplain
Materials
Aluminum Baking Pan Modeling Clay Plastic Shoebox Pitcher Paper Towels Model Houses/Animals/Fences/Trees
Procedure
1. Have students form clay into bottom of aluminum baking pan 2. Students will create a river in the clay 3. Place houses/animals/fences and trees in the floodplain 4. Pour water at the start of the river 5. Students record observations 6. Put aluminum foil at the top of the river. (This will simulate an
urbanized environment) 7. Pour the water on the aluminum foil. 8. Students record what happened to the floodplain using the
VENN Diagram 9. Design ways to keep the floodplain from flooding. 10. Test to see if those designs worked 11. Record why it worked or why it didn’t and other possible ideas
