There are other variables involved and these are; Fixed variables unless indicated Temperature ¨ Water potential of potato initially ¨ Size of potato ¨ Light intensity ¨ Mass of potato dependent variable ¨ Volume of solution potato chip is in ¨ Type of potato- different potatoes may absorb at different rates. ¨ Time left in solution ¨ Surface area of potato chip ¨ Use the same balance to measure chip Concentration of soultion- Independent variable To conduct a fair test, these factors have to be controlled.
