How Rain Forms
An air parcel is a group of air moving together.
On Day 1 and Day 2, the air had the same amount of water vapor.
It rained on Day 2, but not on Day 1.
What was different on Day 2?
A. The air was warmer and rose up
B. The air was cold and stayed still
C. The air sank down
D. The air did not move
Answer: A The air was warmer and rose up
Why: Warm air rises, cools, and can make rain.
Which type of air can hold more water vapor?
A. Cold air
B. Warm air
C. Dry air
D. Windy air
CHALLENGE: Whole group run in place. 30 seconds. 300pts
Answer: B
Why: Warm air can hold more moisture, which helps form rain.
Sonya put a glass of water on the table and left the room. When she came back, she found water drops on the outside of the glass. Where did the water on the outside of the glass come from?
a The air in the room. Water vapor in the air turned into liquid water.
b The air in the room. Oxygen in the air turned into liquid water.
c Water inside the glass. The water leaked through the glass.
d Water inside the glass. The water moved along the surface of the glass.

On two days, the air had the same moisture.
Only one day had rain.What helps rain form?
A. Air going down
B. Air staying still
C. Air rising up
D. Air disappearing
CHALLENGE: Whole group squats! 20! 400pts
Answer: C. Air rising up
Why: Rising air cools and forms clouds and rain.
What usually happens when warm, moist air rises?
A. It gets warmer and disappears
B. It turns into rocks
C. It cools and forms clouds
D. It stays the same
Answer: C It cools and forms clouds
Why: Rising air cools, and the water vapor turns into clouds that can bring rain.
The air temperature of Lawrence is higher than the air temperature of Norristown. What is the main cause for the different air temperatures?
a There was less wind in Lawrence and more wind in Norristown. Wind moved more energy out of the air in Norristown than in Lawrence.
b More energy from the sun is transferred to the air in Lawrence than in Norristown, and that energy is transferred from the air to the ground below it.
c More energy from the sun is transferred to the ground in Lawrence than in Norristown, and that energy transferred to the air above it.
d The heat from the center of Earth transferred more energy to the ground in Lawrence than in Norristown, and that energy transferred to the air above it.
c More energy from the sun is transferred to the ground in Lawrence than in Norristown, and that energy transferred to the air above it.

An air parcel can move up or down.When is rain most likely to happen?
A. When air sinks
B. When air rises
C. When air stops
D. When air spreads out
Challenge: Whole Group, Run in place. 30 seconds 500pts
Answer: B
Why: Rising air helps clouds and rain form.
Two air masses are forming clouds.Air Mass A is warm and rising quickly.Air Mass B is cool and barely rising.Which air mass will most likely produce more rainfall?
A.Air Mass A, because warm air can hold more water vapor and rises higher.
B.Air Mass B, because cool air creates more clouds.
C.Air Mass A, because warm air sinks and forms rain.
D.Air Mass B, because cool air rises faster than warm air.
A.Air Mass A, because warm air can hold more water vapor and rises higher.
Ian left a cup of hot chocolate in a cool room. His mother tells him that his hot chocolate will get cold if he forgets to drink it. How cold could it get?
a Colder than the temperature of the room. It will keep cooling down for as long as he leaves it in the room.
b Only a little colder. It started out much hotter, so it will stop cooling down before it reaches the same temperature of the room.
c Only a little colder. It will stop cooling down when its temperature is about halfway between its starting temperature and the temperature of the room.
d Only as cold as the temperature of the room. It will stop cooling down when it is exactly the same temperature as the room.

Air that is warm and moving up can change.What happens next?
A. It turns into clouds
B. It turns into rocks
C. It disappears
D. It stays warm forever
Answer: A It turns into clouds
Why: Rising air cools and forms clouds, which can bring rain.
Two storms formed under different conditions. Storm A: The air is warm and humid, but there is very little wind, so the air rises slowly.Storm B: The air is warm and humid, and strong winds push the air upward quickly.Which storm will most likely produce more rainfall, and why?
A. Storm A, because slower rising air makes bigger clouds
B. Storm B, because stronger upward motion helps more water vapor condense
C. Storm A, because wind stops rain from forming
D. Storm B, because wind removes moisture from the air
B Storm B, because stronger upward motion helps more water vapor condense
Why: Both storms have warm, moist air, but Storm B has stronger upward movement, which causes more cooling and condensation—leading to heavier rainfall.
Jake put a bottle of water on the desk and left the room. When he came back, he found water drops on the outside of the bottle. Where did the water on the outside of the bottle come from?
a The air in the room. Oxygen in the air turned into liquid water.
b The air in the room. Water vapor in the air turned into liquid water.
c Water inside the bottle. The water leaked through the bottle.
d Water inside the bottle. The water moved along the surface of the bottle.
b The air in the room. Water vapor in the air turned into liquid water.

An air parcel is an amount of air that moves together. On Day 1 and Day 2, the air parcel above Anzac started with the same amount of water vapor in it.
It rained at the end of Day 2 but it did not rain at the end of Day 1. What could have been different on Day 2 to cause rainfall?
a The air parcel was cooler than the surrounding air on Day 2, so it gained energy on Day 2 but not on Day 1.
b The air parcel was warmer than the surrounding air on Day 2, so it gained energy on Day2 but not on Day1
c The air parcel was warmer than the surrounding air on Day 2, so it lost energy on Day 2 but not on Day 1.
d The air parcel was at the same low temperature as the surrounding air on Day 2, so it had low energy on Day 2 but not on Day 1.
c The air parcel was warmer than the surrounding air on Day 2, so it lost energy on Day 2 but not on Day 1.
Dayton experienced two rainstorms in June.
Storm 1 produced more rainfall than Storm 2.The surrounding air temperature was the same before both storms.What conditions could have caused Storm 1 to produce more rainfall than Storm 2?
A.Before Storm 1, Dayton could have been cooler than before Storm 2 and windy.Wind pushed the cooler air parcel higher, allowing it to gain more energy.
B.Before Storm 1, Dayton could have been cooler than before Storm 2 and windy.Wind caused cooler air from above to move downward, causing the surface air parcel to lose more energy.
C.Before Storm 1, Dayton could have been warmer than before Storm 2 and windy.
Wind pushed more water vapor out of the warmer air parcel.
D.Before Storm 1, Dayton could have been warmer than before Storm 2 and windy.Wind pushed the warmer air parcel higher, causing it to lose more energy.
D.Before Storm 1, Dayton could have been warmer than before Storm 2 and windy.
