WP 1.3: Investigating Condensation

Objective: KWBAT use models to collect evidence of why and when condensation occurs.

Part 1: Warm Up

Water is an important part of weather. After a rainstorm, rainwater gathers on the pavement, but soon after, it is gone.

Look at the images and answer the question below.

What do you think happened to the puddle from Day 1 to Day 2? Where did the water go? Answer in complete sentences and use the vocabulary from the word bank (3 vocabulary words minimum!)

Evaporation- sun- energy- water- water vapor-air-gas

Brayan and Julian are outside playing soccer on a summer day. They decide to take a break and get a drink. Julian picks up his cold water bottle and notices it has water droplets all over it.



Explain: Where did the water droplets come from?

2

Categorize these images based on what you have learned in the previous lesson.

  • More Rain
  • Less Rain

Tell me about the worst weather you have ever experienced.
Where did it happen? Describe what the weather was.



Part 2: Discussing Air Parcels

In this lesson we will investigate: why and when does condensation happen in the air to produce rain? Remember that condensation is when water vapor (gas) in the air turns to liquid water.

To investigate this question, we will examine what scientists call an air parcel.


1

When water evaporates, what is an air parcel filled with?

Categorize the items into the correct category based on what you just reviewed.

Hint: Two Items per category!

  • We can visibly see Air Parcels in the sky.
  • Air parcels are represented by wide rectangles in the Weather Patterns Sim.
  • Studying a smaller section of air helps scientists see how air moves through the Earth System
  • precipitation is when water vapor (gas) in the air turns to liquid water.
  • True
  • False

Part 3: Simulating Condensation

  1. Launch the Weather Patterns Simulation and select Lab mode.
1

  1. Set the “Surrounding Air Temperature”
  2. Test 1: 20ºC
  3. Test 2: 4ºC
  4. Set the “Air Parcel Temperature” to 37ºC for both tests.
  5. Set the “Air Parcel Water Vapor” at 40kg.
  6. Run the simulation and observe what happens in the air parcel.
  7. Analyze the results. Record data in the table below.
See slides for the correct setup for each test.

1

Which test had more energy transferred out?

1

Which test had more condensation (total liquid)?

1

How does energy transfer cause water vapor to turn to liquid water?

(hint: what happens when energy transfers out of the air parcel?)

Sentence Starter:
When energy transfers out of the air parcel...

1

What do you think caused one air parcel to have more condensation than the other?

Sentence Starter:
One air parcel had more condensation because...


Part 4: Reflecting on Condensation

Remember, that the direction in which energy transfers indicates how the temperature will change. Condensation is also evidence of energy transfer.

1

In the following image, energy is being transferred out of the air parcel and to the surrounding air.


What will happen to the temperature of the air parcel? Will condensation occur?

Select the two correct responses.

In the following image, energy is being transferred out of the surrounding air and into the air parcel.


What will happen to the temperature of the air parcel? Will condensation occur?

Select the two correct responses.


Part 5: Exit Ticket

On a cold, winter morning, Mr. Moreno was looking outside of his window. He was feeling so cold so he turned on his heater. As he sits down, he notices water droplets forming on the inside of his window. His window was covered with liquid water droplets like the image above.
1

The water droplets formed on the window due to the process of...

0

Explain why liquid water droplets formed on the inside of the window. Be sure to use scientific vocabulary from today’s lesson!

Evaporation- sun- energy- water- water vapor-air-gas-condensation

Sentence Starter:
The reason why liquid water droplets formed on the inside of the window was because...
