Nature of Science Quest Review

Science is a body of knowledge based on the study of nature. Section 2 The Study of Life The Nature of Science What is science? Science is a body of knowledge based on the study of nature. The nature, or essential characteristics, of science is scientific inquiry. Scientific inquiry is both a creative process and a process rooted in unbiased observations and experimentation.

Scientific Theory v. Scientific Law Section 2 The Study of Life The Nature of Science Scientific Theory v. Scientific Law A theory is an explanation of a natural phenomenon supported by many observations and experiments over time. A scientific law describes relationships under certain conditions in nature, but does not explain why the relationship is the way it is.

Makes observations and draws conclusions Section 2 The Study of Life The Nature of Science Makes observations and draws conclusions Scientists choose subjects to study and decide what types of data to collect. They analyze the data collected to draw conclusions.

Section 2 The Study of Life The Nature of Science Expands Knowledge Most scientific fields are guided by research that results in a constant reevaluation of what is known. Pseudosciences imitate science, but do not provide science-based explanations.

Challenges Accepted Theories Section 2 The Study of Life The Nature of Science Challenges Accepted Theories Scientists welcome debate about one another’s ideas. Sciences advance by accommodating new information as it is discovered.

These inconsistencies often lead to further investigations. Section 2 The Study of Life The Nature of Science Questions Results Observations or data that are not consistent with current scientific understanding are of interest to scientists. These inconsistencies often lead to further investigations.

Conclusions are reached from the evidence. Section 2 The Study of Life The Nature of Science Tests Claims Science-based information makes claims based on a large amount of data and observations obtained from unbiased investigations and carefully controlled experimentation. Conclusions are reached from the evidence.

Section 2 The Study of Life The Nature of Science Undergoes Peer Review Before it is made public, science-based information is reviewed by scientists’ peers. Peer review is a process by which the procedures used during an experiment and the results are evaluated by other scientists who are in the same field or who are conducting similar research.

Science in Everyday Life Section 2 The Study of Life The Nature of Science Science in Everyday Life A person who is scientifically literate combines a basic understanding of science and its processes with reasoning and thinking skills. Ethical issues must be addressed by society based on the values it holds important.
