Egg Experiment Part 1

What happens to an egg when you put it in vinegar for a week?  

Our experiment involves one hard-boiled egg and one uncooked egg.

First, Jack labeled the hard-boiled egg.

Then he carefully placed each egg into it's own jar.

Then he covered each egg with vinegar.

Jack observed that the eggs were "bubbling up".    The hard-boiled egg had more bubbles.

Now we will observe the eggs for 5 days and see what happens.
