... higher concentrations will cause the chip to become smaller. Variables: Outcome: Mass of potato Input: Concentration of solution 0.2, 0.4, 0.6, 0.8, 1.0 Controlled: Volume of solution, potato size, scales To create a fair test certain aspects of the experiment will have to be kept the same whilst one variable is changed. I have chosen to vary the concentration of the sucrose solution. For the purpose of my experiment I am going to carry out all the experiments at the same time so the temperature is kept the same throughout. The potato chip will be measured before it is put in the solution, and after. This will allow us to see whether osmosis has taken place. The volume of the solution that the potato chips are kept in must be the same. The potato chip must be totally covered in the solution, and the amount of solution will be kept the same because all the potato chips will be the same size. I am also going to use the same balance to weigh my potato chips. This is because the measurements may slightly vary between different sets of scales. Apparatus: • Petri dishes (with lids) • Beaker • Ruler • Scalpel • Cutting board • Sugar solution • Measuring cylinder Plan: The petri dish lids will be labeled 0.0, 0.2, 0.4, 0.6, 0.8, and 1.0. Using the measuring cylinder the correct amounts of sucrose and water for each concentration will be placed into the appropriate pet...
