Materials:
cylinders of potato (using cork borer)
knife
cork borer; one big one, and one small one
4 beakers
Deionized water
salt solutions (1%, 5%, 10%)
digital balance
Glass rod
Procedure:
1. Label 4 beakers (use small—50ml—plastic beakers) with the following: 0 % salt (deionized water), 1% salt, 5% salt and 10% salt. (Label beakers using masking tape – do NOT write on the beakers)
2. Put the correct solution in each beaker. Use enough of the appropriate solution to fill about half of the beaker.
3. Using a cork borer, take four cores from a potato and use a knife to cut four potato cylinders about 3 cms. long. Caution: be very careful with the knife. Always cut away from yourself. Make sure there is no peel left on the cylinder.
4. Place the potato cylinders on weighing dishes and place one dish in front of each beaker. When you are ready, remove one cylinder at a time and weigh it. You should…
