INVESTIGATING HOW OSMOSIS WORKS AGAINST DIFFERENT CONCENTRATIONS OF GLUCOSE SOLUTION PLAN Aim The aim this investigation is to find at what point the water molecules stop moving and when the concentration of sugar and water molecules inside and outside the potato is equilibrium. Research Osmosis is a special kind of diffusion involving water molecules. It occurs when a partially permeable membrane separates two solutions, where water molecules move from a region high water concentration (weak solution) to a region of low water concentration (strong solution). Glucose rich solution will fill with water. Water acts like it is trying to dilute it, so as to 'even up' the concentration on either side of the membrane. Many water molecules (At beginning), fewer water molecules - Partially permeable membrane (The tiny holes in the membrane allow water molecules to pass through, but the Solute molecules are too big). Key: - Water molecules - Sugar molecules Solution before Solution after Weak...
