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. (P3, P4, P6, P7, NOS2)
- Scientific knowledge is open to question and revision as new ideas surface and new evidence is discovered. (P6, NOS3)
- The process of science involves observation, exploration, testing, communication, and application.
- Scientists test their ideas by predicting what they would expect to observe if their idea were true and then seeing if that prediction is correct. (P4, P6)
- Scientists can test ideas about events and processes long past, very distant, and not directly observable.
- Scientists often try to generate multiple explanations for what they observe. (P7)
- Different scientists may interpret the same data in different ways. (P7)
- Hypotheses are potential explanations for what we observe in the natural world. (P6)
- Hypotheses are usually inspired and informed by previous research and/or observations. They are not guesses. (P6)
- Scientists usually work collaboratively.
