Science Coursework: Osmosis Variables Independent variables * The concentration of sucrose (sugar) solution. * The temperature of the solution * The size of the potato chips * The type of potato (pore size) The dependant variable is the change in mass of the potato and will be measured in grams. Prediction I predict that the lower the concentration of the sugar solution, the larger the mass of the potato chip will increase because the cell wall of the potato chip will allow the smaller molecules such as the water molecules to pass through but won't allow bigger molecules to pass through such as the sugar molecules. So if there is a high concentration of sucrose in the solution then their will be less water molecules to diffuse into the potato chip, so more water molecules are needed to dilute the solution, therefore the potato chip will decrease in mass because the water molecules have passed from a higher concentration...
