    guys I have a feeling that the experiment will be on vitamin C.... can somone please mention the dependent, independent controlled variables and how to control them... also if we are needed to draw a graph on it is it one straight line of best fit or a line connecting every two points..
    Go through this and see if it helps.
    Best of luck
