1

Where do water drops come from?

1

Why did water vapor condense on the cup?

1

What is condensation?

0

Check For Understanding:

How do drops of water form?

Phases of Water

Phases of Water

Read the pages below to learn about the different phases of water.


1

Check For Understanding:

Describe the distance and speed of water molecules when they are in water vapor.

1

Check For Understanding:

Describe the distance and speed of water molecules when they are in liquid water.

Water Nanoscale Model

Follow the directions to draw on your model.

Explore TES Simulation / Task 1 Investigating Condensation in the Sim
Step 1: Choose any of the 12 landscapes.
Step 2: Check that the Wind (at the bottom) is OFF and the Water Molecules (in the top right corner) is ON.
Step 3: Observe the movement of the water molecules.
  • Pink molecules represent water molecules as water vapor
  • Blue molecules represent water molecules as liquid water.
Step 4: When you get the notice “this run has ended” Press ANALYZE in the top left corner of the simulation.

TASK 1: Select a water molecule that has formed part of a raindrop (blue). Observe the path of the molecule as you use the slider to scroll back and forth in time. Pay close attention to what happens as the molecules condense to form raindrops.

Describe the distance of water molecules in water vapor before they condense into liquid water

1

What happens at the nanoscale when water vapor condenses into liquid water?

Task 2
TASK 2: Find a place where a lot of liquid water is forming in the atmosphere. Use the Atmosphere Window to zoom in on the molecules and see what happens when water vapor turns to liquid water.

Observe what is happening at the nanoscale (molecules) when water vapor condenses into liquid water to (hint: use the atmosphere window to zoom in and see what happens with the molecules).

What do you notice about when raindrops form?

Raindrops form when _____________

MM 2.3 Condensation Model / Independent Practice
Directions:
  • Add water molecules to each nanoscale zoom-in to show what happens at the nanoscale.
  • Press on the thermometer to choose the temperature for each nanoscale zoom-in.
  • Add labels to each image.

Would a raindrop form if there were just a few water molecules in the air?

0

How do raindrops form?

Criteria For Success:
  • Identify where the water for rain come from
  • Include the amount of water needed for it to rain
  • Identify temperature does rain/water form
  • Describe the phase change that makes rain/water drops
