Video Learning Notes

Food molecules inside organisms undergo chemical reactions where they are broken down and rearranged into new molecules that support growth or release energy. Atoms are conserved during these reactions, meaning they are not lost but simply rearranged. Energy released from breaking chemical bonds powers life processes. Developing and using models helps students visualize and explain these important biological processes, fulfilling NGSS standard MS-LS1-7.

Learning Goals

• Develop a model to describe how food molecules are broken down and rearranged through chemical reactions inside an organism.
• Explain how these chemical reactions form new molecules that support growth or release energy.
• Describe that atoms are conserved during these chemical reactions, meaning matter is neither created nor destroyed.
• Use evidence from models or observations to support explanations about matter and energy flow in organisms.
