In October 1859, the U.S. military arsenal at Harpers Ferry was the target of an assault by an armed band of abolitionists led by John Brown (1800-59).
A tornado appears as a rotating, funnel-shaped cloud that extends from a thunderstorm to the ground with whirling winds that can reach 300 miles per hour. Damage paths can be in excess of one mile wide and 50 miles long. Some tornadoes are clearly visible, while rain or nearby low-hanging clouds obscure others.t is not uncommon to see clear, sunlit skies behind a tornado. 1  Tornadoes cause an average of 70 fatalities and 1,500 injuries in the U.S. each year. 2  The strongest tornadoes have rotating winds of more than 250 mph.
The tornado in a bottle goes pretty fast. It has the speed winds of 60 mph. It doesn't match up with the real tornadoes. Conclusion I can say that my hypothesis failed but that I enjoyed doing my experiment. So my hypothesis didn't work but at least I learned something. Tornado in a bottle Materials â¢ Plastic bottle with cover â¢ Water â¢ Salt â¢ Teaspoon â¢ Liquid detergent â¢ Food coloring The speed of a tornado!! Hypothesis If I research how much the speed of a tornado is will it be the same as the tornado in the bottle? Experiment Independent Variable The independent variable will be the different locations of the tornadoes. Constant The constant will be the tornadoes and the materials I will use, The dependent variable will be the wind speeds of both tornadoes. Dependent variable By Katie Vega
