What is Science?
• Science is a body of knowledge based on the study of nature.

Characteristics of Science
• Uses scientific theory• Expands scientific
knowledge• Challenges accepted
theories• Questions results• Tests claims• Undergoes peer review• Uses metric system

Scientific Theory
• A theory is an explanation of a natural phenomenon supported by many observations and experiments over time.
• A theory is a generally accepted scientific principle.
![Page 5: The Nature of Science Section 1.2 Pages 11-15. What is Science? Science is a body of knowledge based on the study of nature](https://reader036.vdocument.in/reader036/viewer/2022081519/56649efa5503460f94c0cd93/html5/thumbnails/5.jpg)
Expands scientific knowledge
• Most scientific fields are guided by research that results in a constant reevaluation of what is known.
• This reevaluation often leads to new knowledge that scientists then evaluate.
![Page 6: The Nature of Science Section 1.2 Pages 11-15. What is Science? Science is a body of knowledge based on the study of nature](https://reader036.vdocument.in/reader036/viewer/2022081519/56649efa5503460f94c0cd93/html5/thumbnails/6.jpg)
Challenges accepted theories
• Scientists welcome debate about one another’s ideas.
• Sciences advance by accommodating new information as it is discovered
![Page 7: The Nature of Science Section 1.2 Pages 11-15. What is Science? Science is a body of knowledge based on the study of nature](https://reader036.vdocument.in/reader036/viewer/2022081519/56649efa5503460f94c0cd93/html5/thumbnails/7.jpg)
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.
![Page 8: The Nature of Science Section 1.2 Pages 11-15. What is Science? Science is a body of knowledge based on the study of nature](https://reader036.vdocument.in/reader036/viewer/2022081519/56649efa5503460f94c0cd93/html5/thumbnails/8.jpg)
Test Claims
• Science-based information makes claims based on a large amount of data and observations obtained from unbiased investigations and carefully controlled experimentation.
![Page 9: The Nature of Science Section 1.2 Pages 11-15. What is Science? Science is a body of knowledge based on the study of nature](https://reader036.vdocument.in/reader036/viewer/2022081519/56649efa5503460f94c0cd93/html5/thumbnails/9.jpg)
Peer Review
• 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.
![Page 10: The Nature of Science Section 1.2 Pages 11-15. What is Science? Science is a body of knowledge based on the study of nature](https://reader036.vdocument.in/reader036/viewer/2022081519/56649efa5503460f94c0cd93/html5/thumbnails/10.jpg)
Uses metric system
• The metric system uses units with divisions that are powers of ten.
• The metric system is also known as the International System of Units or SI
• In biology, the most common SI units are:– meter (length)– liter (volume)– gram (mass)– second (time)

What Science is not!
• Claims not supported by scientific explanations are not science.
• Examples: Astrology, horoscopes, psychic reading, tarot and palm reading, physiognomy, and phrenology are all non-science
![Page 12: The Nature of Science Section 1.2 Pages 11-15. What is Science? Science is a body of knowledge based on the study of nature](https://reader036.vdocument.in/reader036/viewer/2022081519/56649efa5503460f94c0cd93/html5/thumbnails/12.jpg)
• These practices are called pseudosciences and are often driven by cultural and economic factors
• Pseudoscience tries to imitate real science, but is not supported by scientific explanation.

Science in your life
• Almost every aspect of your life is somehow affected by science
• Examples: Forensics, medical advances, space exploration, and agriculture are a few examples
• In today’s world, scientific literacy is a necessity– A person who is scientifically literate combines a
basic understanding of science and its processes with reasoning and thinking skills

Ethics
• Ethics are a set of moral principles or values
• Some advances in science raise ethical issues for a society
• Examples: Genetic engineering, cloning, euthanasia, cryonics, global warming, deforestation, and pollution
