Effect of Air on Tornado Height by Science Student
2
Hypothesis

• If the inflow of air is increased then the height
  of the tornado will also be increased.

3
Experimental Design

• I.V. Inflow of Air (Chamber Opening in cm)
• D.V. Tornado Height (cm)
• Constants 1) Temperature of water
• 2) Amount of dry ice
• 3) Room Temperature (65 F)
• 4) Size of Chamber
• 5) Speed of Fan
• Control Chamber Closed (0 cm)
