Photosynthesis Lab
Storing the Sun’s energy
Energy from the sun can be stored in various ways!
Storing the Sun’s energy
Solar collectors
Storing the Sun’s energy
Wind turbines
Storing the Sun’s energy
Hydroelectric Dams
Storing the Sun’s energy
Fossil Fuels
COAL
GASOLINE/MOTOR FUELS
NATURAL GAS
Storing the Sun’s energy
Wait …. fossil fuels store the sun’s energy????
Yes!
Storing the Sun’s energy
Plants use to capture the sun’s energy!
CO2 + H2O C6H12O6 + O2 (carbon dioxide) + (water) (glucose) +
(oxygen)
photosynthesis
Photosynthesis
CO2 + H2O C6H12O6 + O2 This looks like a chemical reaction!!
Where does the sun’s energy enter into this process???
3 things are needed for this reaction to occur Chlorophyll Some enzymes Light!!
Photosynthesis
You all know that the rate of a chemical reaction can vary Brainstorm with your table partner at least 3 ways
that the rate of a chemical reaction can be increased or slowed.
Photosynthesis
Now brainstorm specific ways that you can speed up or slow down the rate of photosynthesis.
Photosynthesis Lab
Your project will be to: Use a water plant (Elodea) to explore the process of
photosynthesis. Determine the rate of photosynthesis using ambient
room light and room temperature. Determine the rate of photosynthesis after varying
one and only one variable in your reaction vessel.
