Current through Reg. 49, No. 38; September 20, 2024
(b) General requirements. This course is recommended for students in Grades
11 and 12. Prerequisite: Biology, and one credit of the following: Applied Physics and Engineering,
Chemistry, Integrated Physics and Chemistry (IPC), or Physics. Students must meet the 40% laboratory and
fieldwork requirement. This course satisfies a high school science graduation requirement. Students shall be
awarded one credit for successful completion of this course. Students may take this course with different
course content for a maximum of three credits.
(c) Introduction.
(1) Career and technical education instruction provides content aligned
with challenging academic standards and relevant technical knowledge and skills for students to further their
education and succeed in current or emerging professions.
(2) The
Science, Technology, Engineering, and Mathematics Career Cluster focuses on planning, managing, and providing
scientific research and professional and technical services, including laboratory and testing services, and
research and development services.
(3) Scientific Research and
Design allows districts and schools flexibility to develop local curriculum to supplement a program of study
or coherent sequence. The course has the components of any rigorous scientific or career and technical
education (CTE) program of study, including problem identification, investigation design, data collection,
data analysis, formulation, and presentation of conclusions. These components are integrated with the CTE
emphasis of helping students gain entry-level employment in high-skill, high-wage jobs and/or continue their
education.
(4) 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.
(5) Scientific hypotheses and theories. Students are
expected to know that:
(A) hypotheses are tentative and testable statements
that must be capable of being supported or not supported by observational evidence. Hypotheses of durable
explanatory power that have been tested over a wide variety of conditions are incorporated into theories;
and
(B) scientific theories are based on natural and physical
phenomena and are capable of being tested by multiple independent researchers. Unlike hypotheses, scientific
theories are well established and highly reliable explanations, but they may be subject to change as new
areas of science and new technologies are developed.
(6) Scientific inquiry. Scientific inquiry is the planned and deliberate
investigation of the natural world using scientific and engineering practices. Scientific methods of
investigation are descriptive, comparative, or experimental. The method chosen should be appropriate to the
question being asked. Student learning for different types of investigations include descriptive
investigations, which involve collecting data and recording observations without making comparisons;
comparative investigations, which involve collecting data with variables that are manipulated to compare
results; and experimental investigations, which involve processes similar to comparative investigations but
in which a control is identified.
(A) Scientific practices. Students should
be able to ask questions, plan and conduct investigations to answer questions, and explain phenomena using
appropriate tools and models.
(B) Engineering practices. Students
should be able to identify problems and design solutions using appropriate tools and models.
(7) Science and social ethics. Scientific decision
making is a way of answering questions about the natural world involving its own set of ethical standards
about how the process of science should be carried out. 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).
(8) Science consists
of recurring themes and making connections between overarching concepts. Recurring themes include systems,
models, and patterns. 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, while models allow for boundary
specification and provide tools for understanding the ideas presented. 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.
(9) Students are encouraged to participate in
extended learning experiences such as career and technical student organizations, other leadership or
extracurricular organizations, or practical, hands-on activities or experiences through which a learner
interacts with industry professionals in a workplace, which may be an in-person, virtual, or simulated
setting. Learners prepare for employment or advancement along a career pathway by completing purposeful tasks
that develop academic, technical, and employability skills.
