The hypothesis is that the higher the water temperature, the larger the diameter of the tornado's core.

You will build a tornado chamber, prepare samples of water at different temperatures, place a plate of water in the chamber, add dry ice, and turn on the exhaust fan.

You will need an electrical drill, Perspex, wooden boards, wooden blocks, a bathroom exhaust fan, measuring tape, dry ice, an extension cord, a metal plate, hot water, gloves, a stopwatch, and superglue.

The results showed that the diameter of the tornado's core was largest when the water was at 30 degrees Celsius. The hypothesis was not accepted because the diameter did not increase accordingly as the water temperature increased.

This science project is interesting because it explores the science behind the formation of tornadoes and how water temperature affects the size of a tornado's core.

Consider experimenting with more temperatures and finding the peak when the diameter is at its largest. Also, consider what difference would be observed if the size of the chamber was increased or decreased.
