Life Science, Nature and Process of Science
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.
- Science is both a body of knowledge and the process for building that knowledge.
- Science focuses on natural phenomena and processes.
- Scientists strive to test their ideas with evidence from the natural world; a hallmark of science is exposing ideas to testing.
- Scientific knowledge is open to question and revision as new ideas surface and new evidence is discovered.
- Science is ongoing; answering one scientific question frequently leads to additional questions to be investigated.
- The real process of science is complex, iterative, and can take many different paths.
- The process of science involves observation, exploration, testing, communication, and application.
- Scientists test their ideas (hypotheses and theories) by figuring out what expectations are generated by an idea and making observations to find out whether those expectations are borne out.
- Scientists look for patterns in their observations and data.
- Researchers share their findings with the scientific community through scientific publications.
- Hypotheses are proposed explanations for a narrow set of phenomena.
- Hypotheses are usually inspired and informed by previous research and/or observations. They are not guesses.
- Science depends on communication within the scientific community.
- Scientists usually work collaboratively.
- Scientists scrutinize each other's work through peer review and other processes.
- Science relies on the accumulated knowledge of the scientific community to move forward.
- Anyone can participate in science, but the pursuit of science as a career often requires extensive formal training.
- Scientific knowledge helps us make decisions that affect our lives every day.
