Why is the Scientific Method used in science?
The Scientific Method helps you put together experiments, use data to find conclusions and interpret them.

What do scientists do when experiments are not possible?
When a controlled experiment is not possible, why do scientists try to identify as many relevant variables as possible? In science, what is a theory? What is bio? Ask a question, form a hypothesis, set up a controlled experiment, record and analyze results, draw a conclusion.
What happens during a controlled experiment?
In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. The researcher can operationalize (i.e. define) the variables being studied so they can be objectivity measured.
