Modeling Photosynthesis

Thank you Barbara for leading this chemistry lesson!

Why, and how, do plants release oxygen? Using gum-ball models of molecules, we discovered that when plants break down H20 and carbon dioxide to make sugar, oxygen atoms are left over!

Building the ingredients plants need: water and carbon dioxide molecules

Each group first built the reactants needed for photosynthesis: 3 water molecules and 3 carbon dioxide molecules

After taking the water and carbon dioxide molecules apart, students used their atoms to build a sugar molecule

Sugar molecules are long!

Ta da! 1 sugar molecule to give the plant energy; lots of (yellow) oxygen molecules left over for us to breathe!
