Step 1:
Using a cork borer to take samples of the potato with the same diameter to make the results equal, using the same potato
Step 2:
Using a ruler to measure 3cm of the potato and then cut the potato up until 3cm, then using a ruler for the length to measure the using a scale to measure the mass
Step 3
Record the length and mass, the. Place the potato in the boiling tube
Step 4
Get at eye level and then measure 10ml of distilled water in the measuring tube, the. Pour in the boiling tube with the potato
Step 5
Then repeat for the other two pieces of potato cut, but with different types of water for example one with sugar and the other with even more sugary that’s heavily concentrated
Step 6
Leave the potato’s
in the solution for a long period of time (even better if 24 hrs)
Step 7
Using the scale again measure the mass of the potato after being submerged, and also using a ruler measure the length, then record this data and repeat for the other potato’s. (MAKE SURE TO DRY THE POTATO FIRST BEFORE DOING ANYTHING!)
Step 8
Using the data collected you find out the percentage change:
Percentage change = change in mass (g) over initial mass (g) multiplied by 100
