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 ____________________

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 ____________________

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 ____________________

What do the molecules in liquid water look like?

How did the molecules move from water vapor (gas) to liquid water?

What happens to the temperature when water vapor (gas) condenses into water (liquid)?

What was the phase of matter and distance between the water molecules before they condense?

Sentence starter:

Before the water molecules condensed, the phase was ____________________ and the distance between the molecules were ____________________

What was the phase of matter and distance between the water molecules after they condense?

Sentence starter:

After the water molecules condensed, the phase was ____________________ and the distance between the molecules were ____________________

Do all the water vapor molecules that condensed into liquid water form rain droplets?

Re-watch in the sim from the beginning, and you should notice that when the water vapor condenses into liquid water, it does not fall as rain right away.

What do you notice about when raindrops form?

Sentence starter: Raindrops form when __________________

How do raindrops form?

Sentence starter:

Raindrops form when _______________________
