1. Tornado Trouble Jordan Tzabari What is the effect of water
temperature in degrees Celsius on the width of the diameter of a
I chose this project because I am interested in how tornados
It Intrigues me how destructive tornados can be.
I hope to answer the questions I have and learn more about
Most tornados occur in the United States.
Tornados form by warm air that rises in a thunderstorm where
winds get sucked up in a circular motion
Tornados form under thunderclouds which led to the belief that
water has an effect on their size.
If the change in temperature of 10, 20, 30, 40, and 50 degrees
Celsius is related to the diameter of a tornados core in
centimeters, then the size of the diameter of tornados core will
increase with the temperature, because tornadoes tend to form under
1 Electrical drill
4 glass panels 20cmx 30 cm
2 wooden boards 25cm x 25cm
4 wooden blocks 5cm x 15cm
1 bathroom exhaust fan (on/off switch)
1 measuring tape (cm)
20 groups of dry ice (200 grams)
1 extension cord for the exhaust fan
1 metal plate
20 plates of hot water (heated to various temp.)
1 pair of gloves
1 bottle of silicon (glass)
1. Setup materials as shown in images page.
2. For this experiment the Control Group is 10 degrees Celsius.
The Dependent Variable is the diameter of the tornados core. The
independent variable is the change in temperature, which are 10,
20, 30, 40 and 50 degrees Celsius respectively. A few controlled
variables are the amount of dry ice used (200 grams), the speed of
the exhaust fan (80 CFM) and the size of the box (25cm x
3. Place a sample of water on the metal dish.
4. Heat or chill the water to a temperature of 10 degrees
Celsius which will be the control group.
5.When the optimum temperature is reached, remove the
detachable side of the box bysliding it out of position, and place
the plate of water in the center of the chamber.
7. Procedure 2
6.Using the pair of gloves, place 200 grams of dry ice in the
middle of the water.
* Hold it firmly in the middle until it sets in position*
7. Reposition the detachable side of the box.
8. Turn on the exhaust fan with the switch and set the timer
for one minute.
9.After a minute, observe the early formation of the tornado.
Measure the diameter of the tornados core with the measuring
10. Record observations.
11. Repeat steps 3 to 10 for 4 more trials.
12. Repeat steps 3 to 11 for the changes in water temperature
of 20, 30, 40, and 50 degrees Celsius.
