Now that you understand how you will measure the rate of photosynthesis, write a hypothesis predicting which light source (blue, red, green, or white) will be the most versus the least beneficial for driving photosynthesis. In this experiment, dark is the negative control to show that light is necessary for photosynthesis and all four colored lights are variables we are testing in this experiment. This data could help us establish a positive control for future experiments. For comparison, create a bar graph for plotting the average rates of photosynthesis for each of the light conditions starting with highest rate of photosynthesis to the lowest. For clarity, type the value of every data point next to the plotted data in excel.
