Answer :
They come up with a hypothesis (question to investigate), then they work out what variables and what they will be measuring, keeping the same and changing in the experiment
Basically, they will use the steps in the scientific method, they will repeat from the beginning if the experiment is not as expected

Experiments carried out by a scientist are based on their thinking about a problem.
This problem is derived from what they experience themselves or come from the research of other scientists.
A scientist must use a specific method or technique in accordance with their competence in their respective fields of expertise.
In general they will use scientific methods that have become a general guide for scientists or even a student
This scientific method consists of several stages, namely:
1. Observation,
2. Determine the problem
2. Data, collect information
3. Hypothesis
4. Experiments
5. Analysis
6. Conclusion
7. Compilation of laws or theories
Basically they will use the steps above, if in a certain stage there is a failure they will repeat it from the beginning
In general, each study will follow one or several objects to get a conclusion in the form of problem solving which later might be a theory or law
The basic stages of a research will determine the success of a study
