Students have recently been exploring eggs in Science Club. A few weeks ago we put eggs in vinegar and made predictions about what may happen to the egg. Today we observed that the outer egg shell was dissolved by the vinegar leaving behind only a thin membrane to hold the egg intact. Students got to feel, observe up close with flashlights and magnifying glasses, and even gently bounce the egg! The outside membrane was soft, smooth, wet, and rubbery according to student observation. Then we decided to see how high we could get the egg to bounce before breaking. We started at 2 inches and then it broke!
