Life Science, Nature and Process of Science Concepts:
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details. - 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.
- 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 can test ideas about events and processes long past, very distant, and not directly observable.
- All scientific tests involve making assumptions, but these assumptions can be independently tested, increasing our confidence in our test results.
- Scientists often try to generate multiple explanations for what they observe.
- Different scientists may interpret the same data in different ways; data interpretation can be influenced by a scientist's assumptions, biases, and background.
- 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.
- Scientists usually work collaboratively.
