Current through Reg. 49, No. 38; September 20, 2024
(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 Agriculture, Food, and Natural Resources
Career Cluster focuses on the production, processing, marketing, distribution, financing, and development of
agricultural commodities and resources, including food, fiber, wood products, natural resources,
horticulture, and other plant and animal products/resources.
(3)
Advanced Plant and Soil Science provides a way of learning about the natural world. In this course, students
learn how plant and soil science has influenced a vast body of knowledge, that there are still applications
to be discovered, and that plant and soil science is the basis for many other fields of science. To prepare
for careers in plant and soil science, students must attain academic knowledge and skills, acquire technical
knowledge and skills related to plant and soil science and the workplace, and develop knowledge and skills
regarding career opportunities, entry requirements, and industry expectations. To prepare for success,
students need opportunities to learn, reinforce, apply, and transfer their knowledge and skills and
technologies in a variety of settings.
(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 and other leadership or
extracurricular organizations.
(10) Statements that contain the
word "including" reference content that must be mastered, while those containing the phrase "such as" are
intended as possible illustrative examples.
