Final answer:
Scientists gain knowledge and understanding through the process of scientific investigation, which involves asking questions, forming hypotheses, conducting experiments or observations, collecting and analyzing data, and drawing conclusions based on evidence.
Step-by-step explanation:
Science is a distinctive way of gaining knowledge about the natural world that is based on evidence and logic. Scientists assume that nature can be understood with systematic study; that scientific ideas are open to revision, although sound scientific ideas can withstand scrutiny; and that knowledge is durable but that theories (explanations of observed phenomena) can be changed and thus are provisional.
Scientists obtain new knowledge through the process of scientific investigation. This involves asking questions, forming hypotheses, conducting experiments or observations, collecting data, analyzing the data, and drawing conclusions. Through repeated testing and refinement of hypotheses, scientists gain a better understanding of the natural world and develop scientific theories to explain observed phenomena.
An important aspect of scientific knowledge is that it is based on evidence. Scientists use objective data and empirical observations to support their claims and theories. This evidence can come from experiments, observational studies, or data collected from the natural world.
