Osmosis coursework Aim: To investigate the effect of different concentration of a sugar solution on the amount of osmotic activity between the solution and pear pieces of a given size. Define osmosis: Osmosis is a net movement of water/ solution molecules from a region of high concentrated area to a region of lower concentrated area through a semi-permeable membrane which lets smaller molecules such as water through but does not allot bigger molecules like glucose to pass through. The molecules
