The students will learn that: 1) the variables of light intensity, temperature, carbon dioxide, light quality all influence the rate of photosynthesis. 2) photosynthesis requires carbon dioxide to furnish the carbon required to make glucose.This carbon dioxide will be supplied by sodium bicarbonate dissolved in the water with the plant leaf disks.he students will learn that: 1) the variables of light intensity, temperature, carbon dioxide, light quality all influence the rate of photosynthesis. 2) photosynthesis requires carbon dioxide to furnish the carbon required to make glucose.
Carbon dioxide is an essential reactant for photosynthesis to occur. If there is a higher concentration of carbon dioxide, then the rate of photosynthesis will increase, and v â¦ ise versa. If the concentration of carbon dioxide decreases, then the rate at which a plant photosynthesizes will be slower.Resources: I'm an advanced bio student, and we conducted an experiment to test this.f there is a higher concentration of carbon dioxide, then the rate of photosynthesis will increase, and v â¦ ise versa.
