Photo Log 35: The science fair testing continues...

Our Question Is: What will happen if we leave an egg in different liquids over
two days?

Materials we used: 

4 eggs, 1 cup of coke, 1 cup of vinegar, 1 cup of salt water, 1 cup of milk, and 4 plastic cups.                                   

Step 1: Place 4 eggs in 4 plastic cups.
Step 2: Fill each cup with a different liquid (Vinegar, Salt water, Coke and Milk).
Step 3: Leave for 3 days.

Step 4: Observe what happens to the egg shell over the 3 days in your experimental notebook.

Step 5: Take the eggs out of the liquids, what do you see, smell, feel?
