SKILL P : Planning and Experimental Procedures MARK: NAME: Andy Robertson Centre Number INVESTIGATION: An Experiment Study to Test the effects of changes in light intensity on the rate of photosynthesis of small leaf disks cut from Hibiscus plants. And how a change in the rate can be seen. Research question and how this will determine the investigation. My research question for this experiment is "The rate of photosynthesis will decrease with a decrease of light intensity". This gives me one thing to vary (a cause) and one thing to measure (an effect). In this case the light intensity is the cause and the rate of photosynthesis is the effect. What variables may have an effect on the quantity being measured? Give reasons. Type Of Variable Name Of Variable How The Variable is Made To Act Like It Should Manipulated Variable Light Intensity I varied the light intensity by using a lamp with a 75W bulb in it and...
