In terms of body pH balance, there is no one âcorrectâ reading for the entire body. For instance, healthy human skin has an approximate pH of 5.5 (slightly acidic). Saliva, on the other hand, has a pH of around 6.5â7.4 (teetering on either side of neutral). Your digestive tractâs pH can range from 1.5 to 7.0, depending on what stage of digestion is underway. And when the body is in good working order, human blood reveals a narrow pH window of about 7.35â7.45 (slightly alkaline).
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
Tornadoes are typically identified as a funnel of spiraling air descending from the base of clouds to the earth. The tornado is usually narrow, about 1/2 km wide and rarely does it move more than 20 km. Like hurricanes the precise mechanism of how the funnel forms in not understood.
