Science High School Programs - Biology


  • In Biology, students conduct laboratory and field investigations, use scientific methods
    during investigations, and make informed decisions using critical thinking and scientific
    problem solving. Students in Biology study a variety of topics that include: structures
    and functions of cells and viruses; growth and development of organisms;
    cells, tissues,
    and organs; nucleic acids and genetics; biological evolution;
    taxonomy; metabolism and
    energy transfers in living organisms; living
    systems; homeostasis; and ecosystems and the
  • Nature of science. Science, as defined by the National Academy of Sciences, is the
    "use of evidence to construct testable explanations and predictions of natural phenomena,
    as well as the knowledge generated through this process." This vast body of changing and
    increasing knowledge is described by physical, mathematical, and conceptual models.
    Students should know that some questions are outside the realm of science because they
    deal with phenomena that are not scientifically testable.
  • Scientific inquiry. Scientific inquiry is the planned and deliberate investigation of the
    natural world. Scientific methods of investigation are experimental, descriptive, or comparative.
    The method chosen should be appropriate to the question being asked.
  • Science and social ethics. Scientific decision making is a way of answering questions about
    the natural world. Students should be able to distinguish between scientific decision-making
    methods (scientific methods) and ethical and social decisions that involve science (the
    application of scientific information).
  • Science, systems, and models. A system is a collection of cycles, structures, and processes
    that interact. All systems have basic properties that can be described in space, time, energy,
    and matter. Change and constancy occur in systems as patterns and can be observed,
    measured, and modeled. These patterns help to make predictions that can be scientifically
    tested. Students should analyze a system in terms of its components and how these
    components relate to each other, to the whole, and to the external environment.
