Final answer:
The scientific method involves making observations, formulating a hypothesis, designing and performing systematic and controlled experiments, analyzing data, and refining the hypothesis based on the results, which may contribute to scientific laws or theories. The correct option is A. Scientific method steps
Step-by-step explanation:
The scientific method is a critical procedure used in science to investigate observations, solve problems, and test hypotheses. It starts with making observations of natural phenomena, from which a hypothesis is then inferred and proposed.
This hypothesis should be a testable statement that can be examined through controlled experiments, where only a single variable is changed at a time to isolate its effects.
Experimental design plays an essential role in testing the validity of the hypothesis. Scientists conduct experiments under specific conditions to systematically observe or measure results, thereby providing measurable evidence to support or refute the hypothesis.
After collecting data, the results are analyzed, and the hypothesis is refined based on the evidence gathered during the experimentation.
In summary, the scientific method includes the following steps: observing phenomena, forming a hypothesis, designing and performing an experiment, and drawing conclusions to form a complete understanding of the studied phenomenon, which may, through repeated confirmation, contribute to scientific laws or theories over time. The correct option is A. Scientific method steps
