  • 4.

    Science Models, Laws, Mechanisms, and Theories Explain Natural PhenomenaAH.4

    1. 1.

      Theories are explanations for observable phenomena.6-8.AH.4.1

    2. 2.

      Science theories are based on a body of evidence developed over time.6-8.AH.4.2

    3. 3.

      Laws are regularities or mathematical descriptions of natural phenomena.6-8.AH.4.3

    4. 4.

      A hypothesis is used by scientists as an idea that may contribute important new knowledge for the evaluation of a scientific theory.6-8.AH.4.4

    5. 5.

      The term "theory" as used in science is very different from the common use outside of science.6-8.AH.4.5

  • 5.

    Science is a Way of KnowingAH.5

    2. 2.

      Scientists and engineers rely on human qualities such as persistence, precision, reasoning, logic, imagination and creativity.6-8.AH.7.2

    3. 3.

      Scientists and engineers are guided by habits of mind such as intellectual honesty, tolerance of ambiguity, skepticism and openness to new ideas.6-8.AH.7.3

    4. 4.

      Advances in technology influence the progress of science and science has influenced advances in technology.6-8.AH.7.4
