Name of Project: Fog Formation
Question: In what temperature of water will fog form in?
Hypothesis: The warm water will form fog first because fog is formed when warm and cold air are mixed together with drops of water.
Variables:
Independent: The water temperature
Controlled: soda bottle and dry ice
Dependent: Time it takes to form fog
Materials and Tools:
What is Fog?
Fog is considered a cloud at ground level. Fog is formed with water droplets with a warm air layer and a cold air layer mixed together, causing it to form fog. Fog forms usually at night when there's a gentle breeze and rain on the ground. Fog begins when water vapor condenses into tiny liquid water droplets in the air. Fog can form depending what side of the dew point the temperature is on.
There are many types of fog. Upslope fog is one of them, it forms when light winds push moist air up a hillside or mountainside to a level where the air becomes saturated. Another type is Radiation Fog. It is named this because it is produced by radiational, circular, cooling of the ground. Like clouds, fog is made up of condensed water droplets. Fog is formed in many places but fog can mostly be formed in wet climates because of the water and air. The first way that fog is formed is by infrared cooling.
Fog forms during the night and begins to disappear as the sun rises. If visibility is between half a mile and 11/4 the fog is known as mist.
Fog formation is studied in Earth Science. Fog can form in two ways the first is by cooling air to its dew point, the second is by adding moisture to the air near the ground. Fog only occurs only when the air is cooled below what is called its dew point. ( The dew point is the temperature at which the air will become completely saturated. It is determined by the amount of the moisture in the air, and the temperature. Fog will form when the temperature is close to the dew point).

Conclusion:
My hypothesis was wrong. I thought it would have been the warm water but it was actually the hot water. The hot water turned into fog first because the ice is in the bottle neck and the hot water's steam mixes with the cold air of the dry ice which is causing it to form fog. In my logbook I recorded that bottle B was the second bottle to turn to form fog because the warm water is a type of water that is mixed with hot and cold water.

Materials and Tools:
- 4 soda bottles with the necks the size of an ice cube,
- 4 ice cubes the size of soda bottle necks,
- water-(hot, warm, cold, and regular)
- journal
- 2 thermometers
- a pencil.
- Get all of my materials I need
- Empty or rinse out each soda bottle a couple times, label each soda bottle with a letter A,B,C, and D.
- Fill each soda bottle with 1/4 full with a different temperature of water.
- Place an ice cube in the neck of a soda bottle.
- Record or observe in the journal what is happening, with the water every hour.
