Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details. - Science focuses on natural phenomena and processes.
- Science works only with testable ideas.
- Scientists strive to test their ideas with evidence from the natural world; a hallmark of science is exposing ideas to testing.
- 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 often try to generate multiple explanations for what they observe.
- 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.
- Problem-solving and decision-making benefit from a scientific approach.
