Problem/Question:
How does temperature affect the formation of clouds?
Prediction/Hypothesis:
If cloud formation is affected by temperature then warmer temperatures will form more clouds because there will be more water vapor in the air for clouds to form.
Procedure:
The experiment is to make a cloud in a bottle using different temperature water. The experiment is to make a cloud in a bottle by adding water to the bottle. The water is then emptied from the bottle. Chalk is added to the bottle. The lid is closed and pressure is applied to the bottle by squeezing it. After a minute, the lid is quickly taken off and a balloon is put on the bottle. The bottle is squeezed to fill the balloon with the cloud. After a few minutes the cloud condenses in the balloon. A measurement of the condensation was taken for the results.
· Test Subjects: The test subjects are clouds.
· Control: The control is the clouds formed by the room temperature water.
· Experimental Groups: The experimental groups are the clouds formed by the hot and cold water.
· Dependent Variable: The amount of condensation in milliliters from the cloud that forms.
· Independent Variable: The temperature of the hot and cold water.
· Method used to control variables: A thermometer will be used to take the temperature of the water. A freezer will cool the water. A stove will heat the water.
· Test Equipment: The test equipment will be balloons, 50ml graduated cylinder, chalk, 2-liter soda bottle, water, thermometer, stove, and freezer.
Procedure:
Step 1: gather materials
Step 2: get room temperature water
Step 3: pour water into 2-liter bottle
Step 4: pour out water
Step 5: scrape chalk dust into bottle
Step 6: close bottle
Step 7: apply pressure onto bottle by squeezing with hands
Step 8: wait one minute
Step 9: repeat step 7
Step 10: open cover
Step 11: quickly cover the bottle with the balloon
Step 12: squeeze bottle filling balloon
Step 13: remove balloon
Step 14: tie balloon
Step 15: wait until cloud condenses
Step 16: untie balloon
Step 17: empty water into graduated cylinder
Step 18: measure water
Step 19: empty graduated cylinder
Step 20: repeat steps 2-19 using hot water
Step 21: repeat steps 2-19 using cold water
Step 22: record data
Step 23: repeat steps 1-22 two more times
