Biology: Osmosis Coursework Aim: To investigate the effect of varying the concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size. Background: Osmosis is defined as the movement of water molecules from an area of high water concentration to an area of low water concentration, across a semi-permeable membrane. In a high concentration of water the amount of solute (e.g. sugar) is low and is a weak or dilute solution. In a low concentration of water the amount of solute (e.g. sugar) is high and is called a strong or concentrated solution. When two such solutions are divided by a semi-permeable membrane the water will move from the area of high concentration to the area of low concentration, until both sides are equal (have reached equilibrium). This can be seen in living cells. The cell membrane in cells is semi-permeable...
