(I NEED HELP ASAP ) 4.2.2 Lab: Investigate Cycling of O₂ and CO₂
Earth Science Sem 1
Be sure to:
Wet Lab
Investigate Cycling of O₂ and CO₂
In this investigation, you will observe the release of O₂ and CO₂ into the environment.
Gas production by two types of organisms will serve as evidence of photosynthesis
and cellular respiration in action. In part 1, you will vary the amount of sugar present
and observe the effect on cellular respiration. You will also observe how the rates of
these processes vary as environmental conditions vary. In part 2, you will vary the
amount of light and observe the effect on photosynthesis.
Follow safe practices during this investigation.
• Dispose of the yeast solutions and the water by pouring them down the kitchen
sink. The plants should be placed in the trash.
