3. Modeling Photosynthesis pg. 13-15
Please DO NOT EAT THE CEREAL
unless instructed to do so!!!

4. Before You Begin 1. Read pg. 13 with your table group
Pg. 14 –Look at the arrows to show the materials that enter the leaf cells during photosynthesis.
3. Reactants for photosynthesis
Carbon dioxide—enter leaf through stoma
Water—enter plant through roots
Light—Radiant energy from sun allows photosynthesis to occur
Products of photosynthesis
Glucose—sugar (food), chemical energy for the plant to use
Oxygen—product released during photosynthesis

5. Photosynthesis water sunlight Carbon dioxide glucose oxygen
In the chloroplast using chlorophyll
oxygen

6. Pg. 15 Workbook--Directions
1. From the container of cereal:
Count out 18 of the same color pieces and place them in a pile on the leaf.
Count 12 of another color.
Count 6 of another color.
Write the cereal color in your workbook on pg. 15
3. Make a water molecule (H2O).
4. Make a carbon dioxide molecule (CO2).
5. Continue making water and carbon dioxide molecules until all atoms (cereal pieces) are used up
Cereal Color
# of Pieces
Atoms Represented 18
Oxygen (O) 12
Hydrogen (H) 6
Carbon (C)

7. Answer the following questions in your workbook.
How many molecules (clusters) of water were you able to make?
How many molecules of carbon dioxide were made?
Write and complete the following sentence in your workbook: The reactants of photosynthesis are…
Reaction Time
Energy from sunlight is needed to break the bonds which hold atoms together in the water and carbon dioxide molecules.
Gently shake the leaf to mix up the cereal pieces, making sure to keep all the pieces on the leaf.

8. Answer the following questions in your workbook.
Directions
Now simulate photosynthesis by recombining the atoms to form both the food and waste of plant cells.
Use the same cereal pieces to make a simple sugar molecule called glucose (C6H12O6).
With the remaining pieces, put together pairs of oxygen atoms (O2).
Answer the following questions in your workbook.
4. How many oxygen molecules did you make?
5. How many glucose molecules did you make?
6. Write and complete the following sentence in your workbook: The products of photosynthesis are…

9. 9. How do the total number of reactants and products compare?
