Photosynthesis & Respiration Equation Breakfast
Photosynthesis & Respiration Equation Breakfast
You will be using breakfast cereal to model the chemical equations for photosynthesis and respiration. You may eat your cereal when you have completed the activity; so wash your hands first and then keep your cereal off the desktop and on a sheet of paper.
A. Obtain your cereal and decide which color(s) will represent each of the atoms needed.
1A. Which color represents Carbon? ________________
2A. Which color represents Hydrogen? ______________
3A. Which color represents Oxygen? ________________
B. Photosynthesis chemical equation.
1B. Use your cereal to model the reactants of photosynthesis. Draw them in the space below; be sure to color your drawing to identify the different atoms.
2B. Now model the products of photosynthesis. Draw them in the space below; be sure to color your drawing to identify the different atoms. (hint: see the glucose molecule on the back pg)
3B. Write the chemical equation for photosynthesis using the chemical formulas and words for the reactants and products.
_____________ + _____________ ( _____________ + _____________
_____________ + _____________ ( _____________ + _____________
C. Cellular respiration chemical equation.
1C. Use your cereal to model the reactants of cellular respiration. Draw them in the space below; be sure to color your drawing to identify the different atoms.
2C. Now model the products of cellular respiration. Draw them in the space below; be sure to color your drawing to identify the different atoms.
3C. Write the chemical equation for cellular respiration using the chemical formulas and words for the reactants and products.
_____________ + _____________ ( _____________ + _____________
_____________ + _____________ ( _____________ + _____________
D. Connecting the processes.
