Biology Coursework: Investigation Of Osmosis In Potatoes Aim: To investigate the affect of different concentrations of sugar solution on potato cells. Variables: The variables are; the concentration of sugar in the solution and the mass of the potato cylinder. We will measure the mass of a potato cylinder after a certain amount of time in a certain solution. Fair test: To keep the test fair we need to keep the controls the same. Like keeping the temperature the same so the kinetic energy doesn't cause a faster reaction. Prediction: I think that if the solution is more concentrated with sugar then the mass should go down. I think this because the concentration is made even inside and outside of the potato so water has to be removed to equal the concentration levels. I think the opposite will happen in weaker solutions, as water has to be placed in so the potato will swell up and weigh more. Apparatus: This...
