Anchor Descriptor - S8.B.2.1 Explain the basic concepts of natural selection.
-
Eligible Content - S8.B.2.1.1 Explain how inherited structures or behaviors help organisms survive and reproduce in different environments.
-
Alternate Eligible Content - S8.B.2.1.1a Identify structures or behaviors that enable plats or animals to survive in their environment (e.g., size of plant, leaf shape or appendages, coverings, nocturnal behaviors.)
Alternate Eligible Content is designed for students assessed using the PA Alternate System of Assessment (PASA). Essentialized Example resources assist teachers in designing instruction that reduces content complexity while maintaining alignment to academic standards.
