|(a) Implementation. The provisions of this section
shall be implemented by school districts beginning with the 2023-2024
(1) No later than August 31, 2023, the commissioner
of education shall determine whether instructional materials funding
has been made available to Texas public schools for materials that
cover the essential knowledge and skills identified in this section.
(2) If the commissioner makes the determination that
instructional materials funding has been made available, this section
shall be implemented beginning with the 2023-2024 school year and
apply to the 2023-2024 and subsequent school years.
(3) If the commissioner does not make the determination

this subsection, the commissioner shall determine no later than August
31 of each subsequent school year whether instructional materials
funding has been made available. If the commissioner determines that
instructional materials funding has been made available, the commissioner

(b) General requirements. This course is recommended
for students in Grades 11 and 12. Prerequisites: one credit in chemistry
and Biotechnology I. This course satisfies a high school science graduation
requirement. Students shall be awarded one credit for successful completion
of this course.
(1) Career and technical education instruction provides
content aligned with challenging academic standards, industry-relevant
technical knowledge, and college and career readiness skills for students
to further their education and succeed in current and emerging professions.
(2) The Science, Technology, Engineering, and Mathematics
(STEM) Career Cluster focuses on planning, managing, and providing
scientific research and professional and technical services such as
laboratory and testing services and research and development services.
(3) Biotechnology II has the components of any rigorous
scientific or bioengineering program of study. This course applies
the standard skills mastered in Biotechnology I and includes additional
skills related to assay design, protein analysis, applications of
genetic engineering, and quality management. After taking this course,
students should be prepared for entry-level lab technician jobs.
(4) 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 currently scientifically testable.
(5) 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;
(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 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
(7) 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
a tool 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.
