5. Immerse the bag in the beaker of solution 6. Allow experiment to stand for 30 mins and record the final color of the bag’s solution 7. Test the liquid in the beaker and in the bag for the presence of glucose. 1. Obtain six 30-cm pieces of 2.5 cm presoaked dialysis tubing 2. Tie a knot in one end of each piece of dialysis tubing to form 6 bags. Pour approximately 15-25 mL of each of the varying solutions; remove excess air 3. Rinse each of the six bags gently with distilled water 4. Blot the outside of each bag and record data in table 5. Fill each beaker 2/3 full with distilled water, be sure to fully submerge bag 6. Let them stand for 30 mins
7. Remove bags from water, carefully blot, and determine the mass of each bag 8. Record and compare data 1. Pour 100 mL of assigned solution into labeled 250 mL beaker. Slice potato into 3 cm disks 2. Use cork bearer to cut four potato cylinders for each beaker, do not leave any skin in there? 3. Keep potato cylinders covered until ready for balancing 4. Find mass of four cylinders together, record data 5. Cover beaker with plastic wrap to avoid evaporation 6. Allow to stand overnight 7. Remove the cores from the beakers, blot them gently on paper towel, and found their total mass 8. Compare final values, calculate the percent of change 9. Graph individual data and the class average for the percentage change in mass
