When the bottle was squeezed, what happened to the air pressure inside of the bottle (H or L)?

• High

• Low

• Nothing

When you released the bottle after squeezing, what happened to the air pressure inside of the bottle (H or L)?

• High

• Low

• Nothing

Why was the smoke added to the air inside of the bottle?

• To create a visual effect

• To provide particles for cloud formation

• To change the color of the air

• To increase the temperature

Did the cloud form when you applied pressure or released pressure?

• Applied pressure

• Released pressure

• Both

• Neither

Do you think high pressure areas in the atmosphere tend to be clear or cloudy? How about low pressure areas?

• High pressure: clear, Low pressure: cloudy

• High pressure: cloudy, Low pressure: clear

• Both are clear

• Both are cloudy

Why was a match added to the bottle in the experiment?

• To create particles in the air needed to form a cloud.

• To heat the water vapor.

• To change the color of the cloud.

• To remove moisture from the air.

How do clouds form?

• Warm, humid, less dense air rises and water vapor condenses around dust particles.

• Cold, dry air sinks and water vapor evaporates.
