it is a prediction at what you think will be the outcome of the experiment...
When a scientist is trying to solve a problem they need to come up with hypothesis.
There is no fire wood problem and the government isn't trying to solve it.
the problem and the hypothesis are part of the scientific method.
Depending on the 'field ' you are working in it means define what you are trying to solve.
Historians solve many different problems; there is no "key problem"
A problem statement is often defined, in the experimental procedure, as the problem that one tries to solve with the experiment. You must come up with a problem statement first, which is usually in the format of a question, and then design an experiment with which to go about solving your problem and to test your hypotheses, if you had any. It also has to do with science
They keep trying!
The scientist solved his problem by doing it over again several times. Also by constructing a hypothesis.
This refers to the Scientific Method, a several-step method used to intentionally search for an answer. Although details vary, one version of the method is the following: 1. Find a problem. 2. Reseach the problem. 3. Suggest a solution (also called a hypothesis). 4. Test the solution/hypothesis. 5. Look at the results (meaning, ask yourself, 'Did I solve the problem?') 6. Adjust your solution, and retest as necessary.
binding things together
guessing
A scientist formulates a hypothesis or an educated guess, then researches the hypothesis and designs a controlled experiment or a series of controlled experiments to test the hypothesis. Then on the basis of experimentation, the researcher formulates a conclusion or solution of the problem.
