Let's begin with a hypothesis:

Where do you think clouds come from?
Remember what we've been learning about air movement and convection cycles, now consider how moisture in the air might be connected to that process.

Conclusion:

Cloud formation occurs when water vapor in the air condenses onto tiny particles known as condensation nuclei. 

This condensation process typically happens in conditions of __________ temperatures and __________ pressure.

Remember what we've been learning about air movement and convection cycles, now consider how moisture in the air might be connected to that process.

What are some important safety precautions to take when conducting an experiment, like the one we did together, where fire and pressurized containers are used?

What factor was manipulated in the experiment? (What is the independent variable being tested?)

Different temperatures of water

Amount of cloud formed

Did the cloud appear in the experiment when he squeezed the bottle or released the bottle?

Squeezed the bottle

Released the bottle

Can you think of anything else we could have manipulated or changed to try and form bigger/better clouds?

Which experimental setup represented the negative control group? The one where we didn't expect a cloud to form.

Glass with hot water and smoke particles

Glass with cold water and smoke particles

Glass with only cold water

Do condensation nuclei make it harder or easier for clouds to form?

Harder

Easier

Which of the following could create condensation nuclei?

A forest fire

Exhaust from cars and trucks

Dust storm

All choices are correct

In the experiment what was used as condensation nuclei?

Bottle

Ash from match

Water

Watch the following video to help answer questions 12 and 13.

Do clouds form in high or low atmospheric pressure systems?

High 

Low

Conclusion:

Cloud formation occurs when water vapor in the air condenses onto tiny particles known as condensation nuclei. 

This condensation process typically happens in conditions of __________ temperatures and __________ pressure.
