Procedures / Method

Procedure to carry out the experiment:

1) Get 8 eggs and soak them in vinegar for about a day or 2 to de-shell them.
*(This must be done as the egg shell is too hard and does not allow water molecules to pass through it, therefore preventing osmosis.)
*( Before de-shelling, the egg is hard and strong. But after soaking it in vinegar, the egg becomes rather translucent, and it feels bouncy and soft)

2) After the egg has completely de-shelled, measure the circumference of each egg using a measuring strip and record it down.

3) Then take use a small measuring scale and measure the mass of each of the eggs.

4) Get 8 containers and fill 2 with the same amount of sucrose solution, 2 with the same amount of tomato sauce, 2 with F&N cherry and 2 with plain water.

5) Soak the eggs into the containers filled with the different solutions.
*( Soaking two eggs in each solution would make the results of the final circumference more accurate.)
*( Make sure that the cover of the container is in place at all times to ensure that heat is not lost or gained and to prevent evaporation. All these can cause the experiment results to be inaccurate)

6) Leave the eggs to soak for 1 day

7) After 1 day, take the eggs out, wipe it dry and measure the new circumference and compare them with the initial circumference for each egg.

8) Do the same for the mass.

9) Compare your results for both the initial and final measurements and see if they fulfill your hypothesis.

10) Conclude your experiment.
