Biology Coursework: an investigation to show how sucrose concentration effects the mass change of a potato chip by osmosis. Planning: Aim: My aim is to see how the concentration of sucrose solution affects the rate and direction of osmosis in a potato chip. I want to find the point at which there is no net movement between a sucrose solution and potato chip. This is where the concentration is the same and the particles reach equilibrium, following the idea of osmosis. I will do this by testing the change in mass of potato chips after being in a number of solutions with different concentrations. Variables: My independent variable is to be changed in order to find the point where there is no net movement between the solution and the potato chip; this is the concentration and it will be measured in Molars. My dependant variable is the percentage change in mass from the potato chip before...
