MS-LS1-7. 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.
Planning and Carrying Out Investigations - Collect data to produce data to serve as the basis for evidence to answer scientific questions or test
LS1.C: Organization for Matter and Energy Flow in Organisms - Cellular respiration is a chemical process in which the bonds of food molecules and oxygen molecules are broken and new compounds are formed that can transport energy to muscles.
Cause and Effect - Cause and effect relationships may be used to predict phenomena in natural or designed systems
