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. (NOS5)
- Science aims to build explanations of the natural world. (P3, P6)
- Science deals with the natural world and natural explanations.
- Scientific knowledge is open to question and revision as new ideas surface and new evidence is discovered. (P6, NOS3)
- 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.
- Scientific observations can be made directly with our own senses or may be made indirectly through the use of tools.
- 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 use multiple research methods (experiments, observations, comparisons, and modeling) to collect evidence. (P2, P3, P4, NOS1)
- 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)
- Science depends on communication within the scientific community. (P7, P8)
