Introduction to the scientific method and experimental design

The scientific method is a systematic approach used by scientists to investigate natural phenomena, acquire knowledge, and test hypotheses. It involves a series of steps designed to ensure objectivity, reproducibility, and validity in scientific research. Here's an introduction to the scientific method and experimental design as applied in biological research: Observation : The scientific process typically begins with observation—carefully observing natural phenomena or patterns in the world around us. Observations may lead to questions or hypotheses about the underlying mechanisms or causes of these phenomena. Question Formulation : Based on observations, scientists formulate specific research questions or hypotheses that can be tested through experimentation. A hypothesis is a tentative explanation or prediction that can be tested through empirical investigation. Background Research : Before conducting experiments, scientists review existing literature and research findings relev...
