Do you know what happens to an egg when you soak it in vinegar? Let us show you!
Now more than ever our teachers are getting creative and expanding their teaching beyond the classroom. Our sixth graders were asked, "What happens to an egg when it comes in contact with vinegar for a long period of time?" When the room was filled with head scratches and looks of uncertainty, we knew it was time for a hands-on science experiment that they can take home. Here is what we learned:
Vinegar is an acid. Eggshells are made of calcium carbonate. If you soak an egg in vinegar the eggshell will absorb the acid and break down, or dissolve. The calcium carbonate will become carbon dioxide gas, which will go into the air. What is left is the soft tissue that lined the inside of the eggshell. It will bounce!
Oh, the things we learn in 6th grade science! Try it at home if you don't believe us!
