Biology Coursework Aim: To investigate how the strength of a solution affects osmosis Prediction: Osmosis is the movement of water from an area of high water potential to an area of low water potential. This movement must take place across a partially permeable membrane such as a cell wall, which lets small molecules (such as water) through but does not allow big molecules (such as sugar) to pass through. Osmosis will continue to occur until both sides have an equal concentration (also known as being in equilibrium) Several things affect the speed of osmosis. These include heat (as the kinetic energy increases movement across the partially permeable membrane), solution concentration (as the concentration gradient will get steeper with a higher concentration) and surface area (as the partially permeable membrane will be bigger, allowing for more water transfer). For this experiment I will be varying the concentration of the solution outside the potato. This means...
