This medical experiment involved 20 subjects, most of whom were conscientious objectors living in the building where many experiments, including the shipwreck experiment, were conducted. They were overseen by a future Nobel Prize winner , and detailed data was kept on each participant in the study. It would never fly now. Even though two trial participants developed life-threatening heart problems because of the vitamin C depletion, Hujoel added, none of the subjects were permanently harmed, and in later interviews several participants said they would volunteer again given the importance of the research. Because of the war and food shortages, there was not enough vitamin C available, and they wanted to be conservative with the supplies, explained Hujoel, who is also an adjunct professor of epidemiology.
The goal of the Sorby investigators was not to determine the required vitamin C intake for optimal health; it was to find out the minimum vitamin C requirements for preventing scurvy. In addition to knitting skin back together, collagen also maintains the integrity of blood vessel walls, thus protecting against stroke and heart disease. In the Sorby trial, researchers assigned participants to zero, 10, or 70 milligrams a day for an average of nine months. The depleted subjects were then repleted and saturated with vitamin C. Ascorbic acid works because oxygen will react with it before it will react with the enzymes in the apple. Once the ascorbic acid gets used up, the oxygen will start reacting with the enzymes in the apple and browning will occur.

I hear you but then i still have a question, if you were to record in on a table or a graph for that matter, how would you measure how much it has browned? By sized? Because i am stuck now. This version of the experiment seems to generate a simple yes or no result as opposed to a measurable DV.
If you need to quantify the dependent variable, perhaps try identifying quadrants on each apple slice and discussing the amount of browning as percentages? Or… maybe counting spots?
