Strand 8.3: LIFE SYSTEMS STORE AND TRANSFER MATTER AND ENERGY

Living things use energy from their environment to rearrange matter to sustain life. Photosynthetic organisms are able to transfer light energy to chemical energy. Consumers can break down complex food molecules to utilize the stored energy and use the particles to form new, life-sustaining molecules. Ecosystems are examples of how energy can flow while matter cycles through the living and nonliving components of systems.

Standard 8.3.2

Develop a model to describe how food is changed through chemical reactions to form new molecules that support growth and/or release energy as matter cycles through an organism. Emphasis is on describing that during cellular respiration molecules are broken apart and rearranged into new molecules, and that this process releases energy. (PS3.D, LS1.C)

• 8.3 Photosynthesis/Respiration Lesson Plan & Resources
  A Google Drive folder with 8.3.1, 8.3.2, 8.3.3 phenomenon-based, 5E lessons that align to the SEEd standards. Lesson folders include lesson plans, a slideshow, and supporting materials for teaching the lesson to your students. Students will use investigations to explore why we need oxygen, learning about the process of cellular respiration and photosynthesis. Students will analyze what happens to an ecosystem when photosynthesis and respiration are not balanced.
