We have been trying to do more science experiments, because they are fun and we can usually learn something too. This week I wanted to try out the Naked Egg Experiment. It is cool in a few different ways. First it just looks really cool, second the fact that the shell disolves off is neat, and third it feels like a rubber ball.
What you learn during the experiment (in basic terms for younger children). The egg shell is made of Calcium. Vinegar is an acetic acid which will break down the calcium egg shell. The first thing you will see in the experiment is the appearence of bubbles around your egg. This is Carbon Dioxide caused from the breakdown of the egg shell. Once the shell is gone you will see that the membrane is holding the egg together and it is rubbery feeling and translucent (which means almost see through).
Not only can you teach the kids a little science with this one but they will have fun.
Put your egg or eggs into a container and cover them with Vinegar. (Make sure the entire egg is covered with vinegar).
Put your container in the fridge for 48 hours. This is how your eggs will look after a few hours. The bubbles are Carbon Dioxide.
After 48 hours rinse off your egg (there will be a residue from the shell but it will rinse right off).
Then let the kids check out the Naked Egg. It is rubbery and will bounce.
Don't bounce them too hard or SPLAT you will have an egg mess (no worries it cleans up quick). This did give the girls an opportunity to see the membrane that was covering the egg (that is the white part on the table)
We still had one left to play with!
Remember Science is fun so let the kids play and have fun with the Naked Eggs.
