This activity models how the atoms of carbon, hydrogen, and oxygen are conserved and flow from the process of photosynthesis to cellular respiration. This cut and paste activity includes a student activity guide and models of water, carbon dioxide, glucose, and oxygen molecules. A teacher's guide also provides you with suggestions to make this a successful activity in your classroom.
This model may help you teach:
NGSS-MS-LS1-6, which states: “Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.” (NGSS Lead States, 2O13)
NGSS-MS-LS1-7, which states: “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.” (NGSS Lead States, 2O13)
NGSS-HS-LS1-5, which states: “Use a model to illustrate how photosynthesis transforms light energy into stored chemical energy.” (NGSS Lead States, 2O13)
NGSS-HS-LS1-7, which states: “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.” (NGSS Lead States, 2O13)
