An investigation to demonstrate the effect of different sucrose concentrations on potato tissues. OSMOSIS: Osmosis is the passage of water from a region of high water concentration through a partially permeable membrane to a region of low water concentration. My main aim is to find out if different concentrations of sucrose solutions cause the mass of a potato chip to increase or decrease. I plan to use 5 different concentrations of sucrose solutions, and for each concentration I will take 3 results. This will determine how much osmotic activity has occurred. I will then find the average weight change for each result. Finally, I will find the average weight change and the average percentage change. The Preliminary Osmosis experiment. Apparatus * Potato chips * 1 measuring cylinder * 3 test tubes * 1 test tube rack * the concentrations of sugar solutions ( 0.5M, 1.00M ) * distilled water (0.00M) * Electronic scales * 1 scalpel * 1 ceramic tile * sticky...
