However as the plant fixes CO2 the carbonic acid concentration decreases and the color indicator returns to red. 5) Variable: Amount of light Control: no light Experiment Question: Would the rate of electron transfer different with different amount of light? Hypothesis: If the amount of light increased then the rate of electron transfer would increase....
