TES 4.2 - Investigating Rainfall Distribution
Objective: KWBAT observe and analyze the interaction between the geosphere and the hydrosphere and identify the cause of the rain shadow effect.
1

Choose the statement that best describes the movement of the water molecule that is outlined in the picture.

1

What are the 2 factors (things) that can cause water vapor to move to different parts of the atmosphere?

SIM: Investigating Rain

Click on the link to go to the sim: https://learning.amplify.com/earthsystem/

GOAL: Use the Sim to gather data about why one side of a mountain could get more rain than the other side, then answer the questions.
  1. Choose Landscape 3.
  2. In RUN, with Water Molecules ON, set Wind to blow RIGHT.
  3. Observe the movement of the water molecules.
  4. Press ANALYZE and use the slider to scroll backward in time.
  5. Press on a water molecule that has just evaporated from the ocean to track its path, and scroll forward in time to observe its path.
  6. In the table, make a tally mark to record what happened to the molecule.
  7. Repeat steps 6-7 for at least 15 more molecules.
0

In the table, make a tally mark to record what happened to the molecule. Repeat steps 6-7 for at least 15 more molecules.

1

What happened to most of the water vapor? The water vapor __________

1

Where did most of the rain fall, on the East side or the West side?

1

How did wind and mountain move the water vapor? Use the words wind and mountain in your answer.

1

Check For Understanding

Why did it rain more on one side of the mountain?

1

Check For Understanding

Why did it it rain less on the other side of the mountain?

The uneven pattern of rain caused by wind and mountains is called the rain shadow effect.

It rains more on one side of the mountain than the other side.

The dry area on one side of the mountain is called a rain shadow.

1

What side of Ferris Island is experiencing a rain shadow (dry area on one side of the mountain) - East Ferris or West Ferris?

Reflecting on the Rain Shadow Model

Rain Shadow Model

GOAL: Show what happens to water in the atmosphere when wind blows towards a mountain.

Criteria for Success:
Arrows show direction of the wind
Criteria For Success:
  • Explain how the wind and mountain move water vapor.
  • Identify what part of the atmosphere where raindrops form.
  • Explain what happens to water vapor at that part of the atmosphere.
1

What happens to water molecules when the wind blows toward a mountain.

Rain shadow Effect - one side of a mountain can get a lot of rain while the other side gets very little rain

Explain what causes the rain shadow effect

Criteria For Success:
  • Identify the amount of water vapor necessary for rain
  • Identify what part of the atmosphere where raindrops form.

Explain what causes the rain shadow effect.
1

Why does it rain more on the west side of the mountain?

1

Why does it rain less on the other side of the mountain?

Modeling Rainfall Patterns
Rain shadow Effect - one side of a mountain can get a lot of rain while the other side gets very little rain

Which side of Maui is getting more rain? How do you know?

0

Which side is the rain shadow? How do you know?

0

We know that the water vapor in the air comes from liquid water that has evaporated.

Where does water vapor come from in this landscape (Maui)?
