Hypothesis Osmosis is defined as the net movement of water or any other solutions molecules from one place where they are highly concentrated to another place where they are less concentrated. This movement must take place across a semi permeable membrane such as a cell wall, which lets smaller molecules like water through but does not allow bigger molecules to pass through. The molecules will continue to spread out until the area where the molecules are found reaches a state of equilibrium, meaning that the molecules are randomly distributed throughout an object, with no area having a higher or lower concentration than any other. For this particular investigation I think that the lower the concentration of the sugar solution the larger the mass of the potato will be. This is because the water molecules pass from a high concentration, i.e. in the water itself, to a low concentration, i.e. in the potato...
