MS-LS1-7

Develop a model to describe how food molecules are rearranged through chemical reactions to release energy during cellular respiration and/or form new molecules that support growth as this matter moves through an organism.

Clarification statement: Emphasis is on describing that molecules are broken apart and put back together and that in this process, energy is released.

Assessment boundary: Assessment does not include details of the chemical reactions for respiration or synthesis.

Performance Level Descriptions

PLDs communicate the knowledge and skills expected of students to demonstrate proficiency in each Learning Standard. NYS assessments classify student performance into one of five levels.

Level 4Level 3Level 2Level 1

Develop multiple models to describe how food molecules are rearranged through chemical reactions to release energy during cellular respiration and describe how new molecules are formed that support growth as this matter moves through an organism.

Develop a model to describe how food molecules are rearranged through chemical reactions to release energy during cellular respiration and/or form new molecules that support growth as this matter moves through an organism.

Given a model, identify evidence that shows how food molecules are rearranged through chemical reactions to release energy during cellular respiration and/or form new molecules that support growth as this matter moves through an organism.

Given a model, identify the new molecules that form when food molecules are rearranged through chemical reactions to release energy during cellular respiration or identify the new molecules that support growth as this matter moves through an organism.
