    beakers, potatoes and the 2 solutions
  • method for osmosis practical:
    1. cut up the potato into 3 identical cylinders and measure the mass with a balance
    2. add to 3 beakers with different concentrations of sugar solution
    3. leave for a day
    4. then take them out to dry and measure their masses again
    5. then calculate the percentage difference
