Instead of sealing the flask in the experimental
group after boiling, Pasteur used a flask with a
curved neck, which allowed air inside and outside
the flask to mix but prevented microorganisms
from entering the body of the flask.
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.
The melting point is independent of the quantity. What changes is the amount of heat which must be supplied.
How does what differ from mass?
Sociological research does present some special requirements that differ from research into physics and chemistry. You are free to do any kind of experiment you want that involves chemicals, but you are not as free to experiment on people or on whole populations. Sociology must depend more on observation of society as it exists, than on experimentation. Nonetheless, the basic principles of the scientific method apply to sociology as they do to any other type of science.
differ from what?
Pasteur's experiment on spontaneous generation showed that microorganisms do not arise spontaneously but are introduced into broths from external sources. Spallanzani's experiment involved boiling nutrient broth in sealed flasks to sterilize it, then observing that no microorganisms grew unless air was allowed to enter the flask, suggesting that microbes were not generated spontaneously but entered from the air.
Pasteur's experiment refuted the theory of spontaneous generation by demonstrating that microorganisms in broth were killed by heat and could only enter through the air. Spallanzani's experiment involved boiling broth in sealed flasks to prevent microorganism entry, concluding that the lack of spontaneous generation was due to the lack of vital force rather than the absence of air.
variable
A conclusion is what the experimenter observes from the experiment andwhether your hypothesis was proven correct or not.While the theory is the facts that is known about the experiment
you have a different variable
A control sample is the experiment under regular conditions. An experimental sample is the experiment in which different variables are changed.
An observation is the changes you see in your experiment. An inference is like drawing a conclusion, I guess...
People watch television for their pleasure, scientists also experiment on them.
No. It is an activity. It is not a science, for the result of a repeated experiment may well differ from other similar experiments. Nor is the result predictable.
Because it helps them know the results of the objects in the experiment and how they differ. This way the scientist knows which succeeded and which failed.
The formula depends on the experiment. For example, the answer will differ between a toss of a coin, a roll of a die, drawing a face card or not from an ordinary deck of cards.
I think it has to do with the quasi you cannot randomly assign people to groups and cannot infer causality. With correlational you are simply examine the relationship between two nominal variables.
