National Science Education Standards

Inquiry

  • Science investigations involve asking and answering a question and comparing that to what scientists already know about the world. (K-4)

    Scientists use different kinds of investigations depending on the questions they are trying to answer. (K-4, 5-8)

    Scientists develop explanations using observations (evidence) and what they already know about the world. Good explanations are based on evidence from investigations. (K-4)

    Scientific explanations emphasize evidence, have logically consistent arguments, and use scientific principles, models, and theories. (5-8)

Life Science

  • An organism's behavior evolves through adaptation to its environment. How a species moves, obtains food, reproduces, and responds to danger are based in the species' evolutionary history. (5-8)

  • Biological evolution accounts for the diversity of species through gradual processes over many generations. Species acquire many of their unique characteristics through biological adaptation, which involves the selection of naturally occurring variations in populations. Biological adaptations include changes in structures, behaviors, or physiology that enhance survival and reproductive success in a particular environment. (5-8)
