Banana's rections to oxygen. :D we're studying that right now.
what kind
I guess the hypothesis would be that you can make a tornado in a jar. This isn't a very good "science project" because while you're making something that may look interesting there isn't a whole lot of "science" you can do with it.
That wold depend entirely on what the project is about. There is no point having an awesomely constructed phrase if it has no relevance to your hypothesis.
A good hypothesis for an earth science research project could be: "Increased levels of carbon dioxide in the atmosphere are contributing to rising global temperatures, leading to more frequent and severe weather events." This hypothesis can be tested by analyzing historical climate data and studying trends in atmospheric carbon dioxide levels.
A good hypothesis for a science fair project using a tornado vortex (tornado in a bottle) could be: "If the speed of rotation is increased in a tornado vortex model, then the strength and duration of the vortex will also increase." This hypothesis can be tested by varying the speed at which the bottle is rotated and observing the resulting vortex's characteristics, such as its height, stability, and longevity.
Question, Hypothesis, Experiment, Results, Conclusion, Analyzing and Interpreting Data, Scientific Method, and reason. Good luck!
A good guess or hypothesis.
It depends on what the project is on.
What is the project on
this is a very good science project
A project about what is the healthies drink in the world
You can do the Coke A Cola and Mentos project.
