Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.

Performance Expectation

Grade:  Middle School (6-8)
Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.

Performance Expectation

Grade:  Middle School (6-8)
Evaluate competing design solutions for maintaining biodiversity and ecosystem services.*

Performance Expectation

Grade:  Middle School (6-8)
Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.

Performance Expectation

Grade:  Middle School (6-8)
Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.

Performance Expectation

Grade:  Middle School (6-8)
Analyze and interpret data for patterns in the fossil record that document the existence, diversity, extinction, and change of life forms throughout the history of life on Earth under the assumption that natural laws operate today as in the past.

Performance Expectation

Grade:  Middle School (6-8)
Apply scientific ideas to construct an explanation for the anatomical similarities and differences among modern organisms and between modern and fossil organisms to infer evolutionary relationships.

Performance Expectation

Grade:  Middle School (6-8)
Analyze displays of pictorial data to compare patterns of similarities in the embryological development across multiple species to identify relationships not evident in the fully formed anatomy.

Performance Expectation

Grade:  Middle School (6-8)
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.

Performance Expectation

Grade:  Middle School (6-8)
Gather and synthesize information about the technologies that have changed the way humans influence the inheritance of desired traits in organisms.
