Answer:
Developing the scientific method.
Step-by-step explanation:
The scientific method is a variety of techniques for investigating certain phenomena, to collect or correct information about the Earth, life on earth or space. There is a set of logical rules that must be adhered to during this scientific investigation, for example that the result can be measured in some way and that the experiment can be repeated. The scientific method was created by the Italian astronomer Galileo Galilei, who devised this system as the best way to arrive at testable hypotheses about a certain scientific question.
