Bioloy Standards 2020

Common Core Standards
Biology is a required, inquiry-based course focused on providing all high school students with
foundational life science content about the patterns, processes, and interactions among living
organisms. The emphasis is on increased sophistication and rigor of a limited number of core
ideas rather than on memorizing a breadth of factual content. Students use prior and new
knowledge to build conceptual understandings based on evidence from their own and others’
investigations. They use their own learning and experiences to support claims and engage in
argument from evidence. The standards provide a depth of conceptual understanding to
adequately prepare them for college, career, and citizenship with an appropriate level of
scientific literacy. Resources specific to the local area as well as external resources, including
evidenced-based literature found within scientific journals, should be used to extend and increase
the complexity of the core ideas.
Content standards within this course are organized according to the disciplinary core ideas for
the Life Science domain. The first core idea, From Molecules to Organisms: Structures and
Processes, concentrates on the structure of cells and how their functions are necessary for
supporting life, growth, behavior, and reproduction. The second core idea, Ecosystems:
Interactions, Energy, and Dynamics, investigates the positive and negative interactions between
living organisms and other biotic and abiotic factors. The third core idea, Heredity: Inheritance
and Variation of Traits, centers on the formation of proteins that affect the trait expression, also
known as the central dogma of molecular biology; the passing of distinguishing genetic
information throughout generations; and how environmental factors and genetic errors can cause
gene mutations. The fourth core idea, Unity and Diversity, examines the variation of traits within
a population over a long period of time that results in diversity among organisms. Integrated
within the disciplinary core ideas of Biology are the Engineering, Technology, and Applications
of Science (ETS) core ideas, which are denoted with an asterisk (*). The ETS core ideas require
students to use tools and materials to solve simple problems and to use representations to convey
design solutions to a problem and determine which is most appropriate.
