Modeling Photosynthesis and Cellular Respiration


Use snap beads to model the reactants and products.

  • Create simple snap bead models to illustrate the reactants and products of photosynthesis and cellular respiration.
  • Use review cards to help distinguish between the processes of photosynthesis and cellular respiration.

Performance Expectations:

MS-PS1-5. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.

  • Science & Engineering Practices

    Developing and Using Models - Develop a model to describe unobservable mechanisms.

  • Disciplinary Core Ideas

    PS1.B: Chemical Reactions - Substances react chemically in characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants.

  • Crosscutting Concepts

    Energy and Matter - Matter is conserved because atoms are conserved in physical and chemical processes.
