What We Did: We put ice in a cup of regular (room-temperature) water.
What We Saw: Small drops of water formed on the outside of the cup.
What did you learn about the temperature when water drops form on the outside of the cup?
Sentence starter: I learned water drops form when the temperature is ____________________

Question 6
6.
What We Did: We put an empty glass in the freezer.
What We Saw: The empty glass still had condensation in it when it came out of the freezer, even though it had no water inside it.
What did you learn about where (what part of the cup) does the water drops forming on the outside of the empty cup come from?
Sentence starter: I learned water drops come from ____________________

Question 7
7.
What We Did: We put a cup of ice water in a bag with no air and compared it to a cup of ice water surrounded by air.
What We Saw: The cup that wasn’t surrounded by air had much less condensation that the cup that was surrounded by air.
What did you learn about where the bigger water drops forming on the outside of the cup that was not in the bag came from?
Sentence starter: I learned water drops come from ____________________

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).
