If the hypothesis is confirmed then you probably consider it a success. But sometimes you can learn something valuable when the hypothesis is disproved (or rejected).
Something important, though, is that the results of the experiment must be repeatable. There is a nice YouTube video on Sixty Symbols channel, where they go to Ethiopia to teach Physics and show how they can demonstrate Physics through experiments using supplies that are readily available to them. They also teach the scientific method. One thing I remember him saying in the video about performing an experiment multiply times for repeated results. He said something to the effect: 3 times is a minimum, 5 times is good, and 10 is great.
It is called an experiment.
Italy was the first country to experiment with colored fire works
The steps in an experiment are called the Scientific Method.
it is called the control of the experiment
The results of an experiment are called your data.
A factor that changes in an experiment is called a variable.
An experiment in which all variables stay the same is called a "controlled experiment".
It works when repeated to get results that are the same
Controlled Experiment :Pcontrolled experiment.
It's called a variable.
The conclusion in an experiment is typically called the "results", "findings", or "summary". It summarizes the key outcomes and insights discovered during the experiment.
The factor that changes in a controlled experiment is called the independent variable.
