The resources above correspond to the standards listed below:

U.S. National Standards

NGSS.MS-LS. LIFE SCIENCE
MS-LS2. Ecosystems: Interactions, Energy, and Dynamics
Students who demonstrate understanding can:
MS-LS2-2. Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.
MS-LS4. Biological Evolution: Unity and Diversity
Students who demonstrate understanding can:
MS-LS4-4. Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment.
MS-LS4-6. Use mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time.
