Osmosis Aim To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size. Scientific knowledge Osmosis is when water from a weak solution goes through a selectively permeable membrane into a strong solution. A selectively permeable membrane is a small water molecule can go through a selectively permeable membrane but larger molecules cannot. Prediction I think that the lower the concentration of the sugar solution in the test tube the larger the mass of the potato will be. This is because the water molecules pass from a high concentration, in the water itself, to a low concentration, in the potato chip. Therefore, the chips in higher water concentrations will have a larger mass than in higher sugar concentrations. Equipment 5 test tubes, white tile, scales, measuring cylinder, ruler, beaker, 6 labels, knife, potato, 80ml sugar solution, 20ml water. Method Using...
