... experiment showed osmosis, where water moves from a dilute solution to a more concentrate solution. To decide what to measurements to use for the main investigation I did some additional experiments. To decide what % sugar solution I should use. I made up several sugar solutions, I weighed and placed a small potato chip in each, I left the experiment for 1hour, I weighed them again. When the solution was more than 20% it was saturated so I used 5 different solutions (0%, 5%, 10%, 15%, 20%) MAIN INVESTIGATION Variables * The independent variable will be the concentration of the sugar. * The Dependant variable will be the density (in g/cm3) of the potato chip * Some of the control variables will be: o The size of potato chips o The amount of sugar solution o The time left in the solution o The temperature Prediction I would expect that, as the concentration of sugar solution increases the mass ...
