Fun Activity Ideas

Disappearing Egg Shell

1/2/2016

​This easy and fun science activity is a great way for your child to learn something new while celebrating a special birthday!
 
Disappearing Egg Shell 

You will need:
· A mason jar (make sure it can fit an egg!)
· White vinegar
· Fresh egg

Instructions:
1. Carefully put the egg into the mason jar.
2. Next, fill the jar with the vinegar, making sure you leave at least about half an inch of room at the top. This is                  important because carbon dioxide bubbles will form and expand from the reaction.
3. Loosely screw on the lid of the jar. This is to allow for the carbon dioxide bubbles to      escape.
4. Let it sit for about 2 days. Make a prediction of what you think will happen!
5. When it is ready, remove the egg and rinse it off with water. Your egg now has no shell! Shine a flashlight up to it to      see what’s inside.

How does it happen?
· Egg shells are made up of calcium carbonate.
· Calcium carbonate dissolves in vinegar and creates calcium ions and carbon dioxide   bubbles.
· You can see the bubbles during the reaction throughout the two days.
· The reaction will stop when there is no shell left to dissolve!
