Actions

A1 Science as Inquiry and Process

B1 Concepts of Physical Science

  • SB Students develop an understanding of the concepts, models, theories, universal principles, and facts that explain the physical world.

    • SB1 Students develop an understanding of the characteristic properties of matter and the relationship of these properties to their structure and behavior.

      • SB1.1 using physical properties (i.e., density, boiling point, freezing point, conductivity) to differentiate among and/or separate materials (i.e., elements, compounds, and mixtures).

    • SB2 Students develop an understanding that energy appears in different forms, can be transformed from one form to another, can be transferred or moved from one place or system to another, may be unavailable for use, and is ultimately conserved.

    • SB3 Students develop an understanding of the interactions between matter and energy, including physical, chemical, and nuclear changes, and the effects of these interactions on physical systems.

    • SB4 Students develop an understanding of motions, forces, their characteristics and relationships, and natural forces and their effects.

C1 Concepts of Life Science

D1 Concepts of Earth Science

  • SD Students develop an understanding of the concepts, processes, theories, models, evidence, and systems of earth and space sciences.

E1 Science and Technology

  • SE Students develop an understanding of the relationships among science, technology, and society.

    • SE1 Students develop an understanding of how scientific knowledge and technology are used in making decisions about issues, innovations, and responses to problems and everyday events.

      • SE1.1 describing how public policy affects the student's life. (e.g., public waste disposal).

    • SE2 Students develop an understanding that solving problems involves different ways of thinking, perspectives, and curiosity that lead to the exploration of multiple paths that are analyzed using scientific, technological, and social merits.

    • SE3 Students develop an understanding of how scientific discoveries and technological innovations affect and are affected by our lives and cultures.

F1-F3 Cultural, Social, Personal Perspectives, and Science

  • SF Students develop an understanding of the dynamic relationships among scientific, cultural, social, and personal perspectives.

    • SF1 Students develop an understanding of the interrelationships among individuals, cultures, societies, science, and technology.

      • SF1.1 investigating the basis of local knowledge (e.g., describing and predicting weather) and sharing that information.

    • SF2 Students develop an understanding that some individuals, cultures, and societies use other beliefs and methods in addition to scientific methods to describe and understand the world.

      • SF2.1 investigating the basis of local knowledge (e.g., describing and predicting weather) and sharing that information.

    • SF3 Students develop an understanding of the importance of recording and validating cultural knowledge.

      • SF3.1 investigating the basis of local knowledge (e.g., describing and predicting weather) and sharing that information.

G1 History and Nature of Science

  • SG Students develop an understanding of the history and nature of science.

    • SG1 Students develop an understanding that historical perspectives of scientific explanations demonstrate that scientific knowledge changes over time, building on prior knowledge.

    • SG2 Students develop an understanding that the advancement of scientific knowledge embraces innovation and requires empirical evidence, repeatable investigations, logical arguments, and critical review in striving for the best possible explanations of the natural world.

      • SG2.1 explaining differences in results of repeated experiments.

    • SG3 Students develop an understanding that scientific knowledge is ongoing and subject to change as new evidence becomes available through experimental and/or observational confirmation(s).

      • SG3.1 revising a personal idea when presented with experimental/observational data inconsistent with that personal idea (e.g., the rates of falling bodies of different masses).

    • SG4 Students develop an understanding that advancements in science depend on curiosity, creativity, imagination, and a broad knowledge base.
