10. keep your settings from #9c (25°c, light intensity of 20, increased co2).

a. what were the bubbles per minute in this setting? bpm

b. now increase the temperature to 40°c. what were your bubbles per minute?

c. based on your data, how does an increase in temperature affect the rate of photosynthesis? (it might to complete #11 before you answer this question.)
the increase in temperature slowed down the rate of photosynthesis.

11. return to your settings from #9c (25°c, light intensity of 20, increased co2).

a. what were the bubbles per minute in this setting?

b. now decrease the temperature to 10°c. what were your bubbles per minute? ++bpm

c. based on your data, how does a decrease in temperature affect the rate of photosynthesis?

12. alter the variables in order to determine which combination leads to the highest rate of photosynthesis.
which combination of settings produced the highest number of bubbles per minute?

a. temperature:
b. light:
c. co2:
how many bubbles per minute did you count for this setting?

13. looking back at your hypothesis from question 8, does your data support your hypothesis? why or why not? (for full credit write two complete sentences.)
