    PHOTOSYNTHESIS LAB
Alyssa Wright VARIABLE: LIGHT INTENSITY AIM: to investigate the effect of light intensity (lux) on the amount of oxygen produced (number of bubbles) HYPOTHESIS: I predict that the rate of oxygen produced increases‚ as the light intensity increases‚ but only to a point. I predict this will happen because the plant will have enough carbon dioxide and water to keep up with the amount of light that there is. When there is less light intensity‚ photosynthesis will happen
