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
Tornado season usually refers to the time of year the U.S. sees the most tornadoes. The peak âtornado seasonâ for the Southern Plains is during May into early June. On the Gulf coast, it is earlier during the spring. In the northern plains and upper Midwest, tornado season is in June or July. But, remember, tornadoes can happen at any time of year. Tornadoes can also happen at any time of day or night, but most tornadoes occur between 4â9 p.m. What is the difference between a Tornado WATCH and a Tornado WARNING? A Tornado WATCH is issued by the NOAA Storm Prediction Center meteorologists who watch the weather 24/7 across the entire U.S. for weather conditions that are favorable for tornadoes. A watch can cover parts of a state or several states.
