SCIENCE COURSEWORK Aim: To investigate how concentration effects osmosis on potato chips. Introduction: I have been asked to investigate the effect of osmosis on potato chips. Osmosis is the diffusion of water from a lower concentration of solute to a higher concentration of solute, through a membrane. I have chosen to investigate the effect of the water potential/concentration of solution on potato chips. This means that I will put potato chips into sucrose solutions of different concentrations. These concentrations would be ones such as these; 0molar, 0.2m, 0.4m, 0.6m, 0.8m, 1.0 and distilled water. There are other factors involved and these are; 1) Temperature 2) Water potential of potato initially 3) Size of potato 4) Light intensity 5) Mass of potato dependent variable 6) Volume of solution potato chip is in 7) Type of potato 8) Time left in solution 9) Surface area of potato chip 10)Use the same balance to measure chip Osmosis is the movement of water down a concentration gradient through a partially permeable...
