Osmosis Investigation

Introduction & Aims At present I am investigating Osmosis, and I have devised a experiment to investigate the rate of it. I have been provided with potatoes, and all the common laboratory equipment. I will look at 2 variables, one discontinuous, one continuous. For my discontinuous veritable I have chosen TYPE OF POTATO. I will have 3 different types of potato, chosen randomly, and numbered A, B & C. For my continuous veritable I have …

…middle of these two. Length Change There was some length change during the experiment, but unlike the mass, all 3 chips decrease at the same rate. Final Conclusion My conclusion is virtually the same as my hypothesis, as all the chips have stayed virtually the same as each other. I could have done the done the experiment again, with more variables, and measuring different aspects of the chip before, e.g. Starch & water content.
