Cloud Formation Model
Follow-Up Questions:
1. Which of your four trials resulted in the best cloud formation?
2. Was cloud formation more impressive when smoke particles were present in the
bottle?
3. Did the cloud appear when you caused high pressure on the air in the bottle (by
squeezing), or when you caused low pressure (by releasing)?
4. Which provided more vapor in the bottle . . . the hot water, or the cold water?
5. Based on your findings, write out a recipe for cloud formation? (3 ingredients or
conditions)
6. In your experiment, what served as the condensation nuclei? What are some other
things that could serve as condensation nuclei?
7. Why did the cloud disappear when you squeezed the bottle? You must use the term
“dew point” in your answer.

8. You can see clouds because they are made up of ??? or ???. Circle two answers.
water vapor . . . . . .water droplets . . . . . . ice crystals
9. As air rises in the atmosphere, is it compressed, or does it expand?
10. What effect does this have on the air’s temperature?
11. Circle the letters of the five situations listed below that will contribute to cloud
formation.
A. Moist air is forced upward as it encounters the Cascade Mountain Range.
B. Tomorrow’s forecast calls for an area of high pressure to be centered over your region.
C. The westerlies cause air to flow down the east side of the Rockies into Denver,
Colorado.
D. During the afternoon, air over a large air force base begins to rise because it is so
much hotter than air over the surrounding forest.
E. In autumn, the Santa Ana winds blow down from the mountain slopes of interior
California out to the sea.
F. Intensely heated air over the equator rises in an area called the intertropical
convergence zone.
G. As part of the global circulation pattern, air 30 degrees north of the equator is sinking
in an area called the horse latitudes.
H. An intense low pressure system moves across the Midwest.
I. A cold air mass from Canada pushes into a mass of warm humid air over Kansas.

Unit 3B Activity 5 Worksheet 1:
Ice as a Temperature Buffer
Latent Heat Investigation
1. What is the temperature, in degrees Celsius, that water normally freezes at?
2. What was the initial temperature of the ice water in your cup?
3. What does your graph show about the temperature of the test tube?
4. Do you notice anything different about the graph of the test tube and the graph of
the foam cup?
5. Why was salt added to the water?
6. What happened to the water in the test tube? What happened to the water in the
cup?
Note:
As water undergoes a phase change, from a liquid to a solid (ice) or a solid to a liquid, it
releases energy (about 80 calories per gram). This energy is called latent energy. Energy
leaving the test tube is being balanced by energy added to the tube. The result is the
temperature remains constant until the whole system has changed state. This thermal
buffering occurs only when both ice and water are present. The same phenomena occurs
when the ice reverts from ice to water.
7. What happens to the temperature of the test tube once the water in the test tube is
all frozen?
8. How are the polar ice caps similar to our experimental set up?
9. What would happen to ocean temperatures following a complete melting of all the
ice that now serves as a thermal buffer?
10. Do you notice anything different about the graph of the test tube and the graph of
the foam cup?
