Matter and Energy in Life
Photosynthesis and Energy Transformation
Use a model to illustrate how photosynthesis transforms light energy into stored chemical energy.
Formation of Carbon-Based Molecules
Construct and revise an explanation based on evidence for how carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form amino acids and/or other large carbon-based molecules.
Cellular Respiration and Energy Transfer
Use a model to illustrate that cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed resulting in a net transfer of energy.
Aerobic and Anaerobic Cycling of Matter
Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.
Biomass and Trophic Levels
Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.
Cycling of Carbon in Ecosystems
Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.
