Pre-Lab Questions 1. Which two variables are controlled in a similar manner?
The two variables that can be controlled in a similar manner are CO2 & the light level. 2. How can you get the results to the investigation faster?
You can get the results to the investigation faster by adjusting the speed at the bottom of the water weed simulation. 3. How will you be able to determine the rate of photosynthesis in this simulation?
One can determine the rate of photosynthesis in the simulation by the amount of bubbles in the water weed after the simulation is done. 4. Write the chemical equation for photosynthesis in the space below
The chemical equation for photosynthesis is

What conditions of light and CO2 (both colour and intensity) would you suggest this student use to optimize the growth of this water plant?
The conditions of CO2 and light that I would suggest a student to use would be blue light and having the CO2 levels at 7.5 along with the intensity of the light being at 7.5 also because this would allow the plant to intake good colours of the light spectrum and it would allow a good amount of intake of carbon dioxide and if the intensity of the light it strong than photosynthesis would move at a faster rate
b. Is there anything else the student would need to optimize growth? Justify your answer.
I honestly think that there is nothing else that the student would need regarding the light but maybe if he wanted to further on the investigation to optimize the growth of the water weed plant he could add minerals and protein to the water that id fundamental to the plant so it can grow faster and make it more healthy strong and durable for his clients.
3. Cutting down a large number of trees in the forested areas contributes to global climate change. What is one reason that cutting down trees would increase the greenhouse
