1. Label 4 containers with your name and the following: distilled water, 1% salt, 3% salt, and 5% salt. 2. Using the cork borer, make 12 cylinders from your potato. Trim them with a knife until they are 3 cm long. Caution: be very careful with the cork borer and knife. Always cut away from yourself. Make sure there is no peel left on the core. (If a cork borer is not available, you may also cut strips of potato using a knife. Try to make them all the same width. ) Place three cores in each of the containers and cover them temporarily. When you are ready, remove the cores and find the mass of each group of three using the balance. Mass all three of them together, not separately. You should mass them to the nearest 0.1 g. Record your data 3. in the data table. 4. Immediately return the cores to the correct container and cover them with the correct solution. Place a lid on each container and set them aside for 24 hours. 5. After 24 hours, remove each set of three cores from their containers. Briefly blot them with a paper towel to remove excess water. Quickly find the mass of each group of 3 and record the mass in the data table. 6. Make observations of the texture, color and flexibility of the cores. Record these observations in the data table. 7. Determine the change in mass by subtracting. If the mass increased over the 24 hours, place a (+) in the data table next to the amount changed. If the mass decreased, place a (-) in the space,
