  • [What is science?: Grades 3-5] Science is both a body of knowledge and the process for building that knowledge. (NOS5)
  • [What is science?: Grades 3-5] Scientists base their ideas on evidence from the natural world. (P3)
  • [What is science?: Grades 3-5] Answering one question often leads to other questions. (P1)
  • [What is science?: Grades 6-8] Science is both a body of knowledge and the process for building that knowledge. (NOS5)
  • [What is science?: Grades 6-8] Science aims to build explanations of the natural world. (P3, P6)
  • [What is science?: Grades 6-8] Science deals with the natural world and natural explanations.
  • [What is science?: Grades 6-8] Scientific knowledge is open to question and revision as new ideas surface and new evidence is discovered. (P6, NOS3)
  • [How science works: Grades 3-5] Scientists observe, explore, discover, and communicate with one another.
  • [How science works: Grades 3-5] Scientific observations can be made directly with our own senses or may be made indirectly through the use of tools. (P3)
  • [How science works: Grades 3-5] Scientists don't always agree with one another. (P7)
  • [How science works: Grades 6-8] The process of science involves observation, exploration, testing, communication, and application.
  • [How science works: Grades 6-8] The real process of science is complex, iterative, and can take many different paths.
  • [How science works: Grades 6-8] Scientific observations can be made directly with our own senses or may be made indirectly through the use of tools.
  • [How science works: Grades 6-8] 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)
  • [How science works: Grades 6-8] Scientists use multiple research methods (experiments, observations, comparisons, and modeling) to collect evidence. (P2, P3, P4, NOS1)
  • [Hypotheses and theories: Grades ] 3-5
  • [Hypotheses and theories: Grades 6-8] Hypotheses are potential explanations for what we observe in the natural world. (P6)
  • [Hypotheses and theories: Grades 6-8] Hypotheses are usually inspired and informed by previous research and/or observations. They are not guesses. (P6)
