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)
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 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)
Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.

Performance Expectation

Grade:  Middle School (6-8)
Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function.

Performance Expectation

Grade:  Middle School (6-8)
Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.

Performance Expectation

Grade:  Middle School (6-8)
Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system.

Performance Expectation

Grade:  Middle School (6-8)
Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.

Performance Expectation

Grade:  Middle School (6-8)
Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
